It\n   * might be for example a function that you passed to Observable's constructor, but most of the time it is\n   * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n   * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n   * the thought.\n   *\n   * Apart from starting the execution of an Observable, this method allows you to listen for values\n   * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n   * of the following ways.\n   *\n   * The first way is creating an object that implements {@link Observer} interface. It should have methods\n   * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n   * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n   * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n   * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n   * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n   * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n   * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n   * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n   * an `error` method to avoid missing thrown errors.\n   *\n   * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n   * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n   * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n   * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n   * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n   * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n   *\n   * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n   * and you also handled emissions internally by using operators (e.g. using `tap`).\n   *\n   * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n   * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n   * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n   * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n   *\n   * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n   * It is an Observable itself that decides when these functions will be called.

It might be useful, if you do not have control over\n * internal scheduler of a given Observable, but want to control when its values are emitted nevertheless.\n *\n * Returned Observable emits the same notifications (nexted values, complete and error events) as the source Observable,\n * but rescheduled with provided scheduler. Note that this doesn't mean that source Observables internal\n * scheduler will be replaced in any way. Original scheduler still will be used, but when the source Observable emits\n * notification, it will be immediately scheduled again - this time with scheduler passed to `observeOn`.\n * An anti-pattern would be calling `observeOn` on Observable that emits lots of values synchronously, to split\n * that emissions into asynchronous chunks. For this to happen, scheduler would have to be passed into the source\n * Observable directly (usually into the operator that creates it). `observeOn` simply delays notifications a\n * little bit more, to ensure that they are emitted at expected moments.\n *\n * As a matter of fact, `observeOn` accepts second parameter, which specifies in milliseconds with what delay notifications\n * will be emitted. The main difference between {@link delay} operator and `observeOn` is that `observeOn`\n * will delay all notifications - including error notifications - while `delay` will pass through error\n * from source Observable immediately when it is emitted.

This is done by subscribing to each Observable in order and,\n * whenever any Observable emits, collecting an array of the most recent\n * values from each Observable. So if you pass `n` Observables to this operator,\n * the returned Observable will always emit an array of `n` values, in an order\n * corresponding to the order of the passed Observables (the value from the first Observable\n * will be at index 0 of the array and so on).\n *\n * Static version of `combineLatest` accepts an array of Observables. Note that an array of\n * Observables is a good choice, if you don't know beforehand how many Observables\n * you will combine. Passing an empty array will result in an Observable that\n * completes immediately.\n *\n * To ensure the output array always has the same length, `combineLatest` will\n * actually wait for all input Observables to emit at least once,\n * before it starts emitting results. This means if some Observable emits\n * values before other Observables started emitting, all these values but the last\n * will be lost. On the other hand, if some Observable does not emit a value but\n * completes, resulting Observable will complete at the same moment without\n * emitting anything, since it will now be impossible to include a value from the\n * completed Observable in the resulting array. Also, if some input Observable does\n * not emit any value and never completes, `combineLatest` will also never emit\n * and never complete, since, again, it will wait for all streams to emit some\n * value.\n *\n * If at least one Observable was passed to `combineLatest` and all passed Observables\n * emitted something, the resulting Observable will complete when all combined\n * streams complete. So even if some Observable completes, the result of\n * `combineLatest` will still emit values when other Observables do. In case\n * of a completed Observable, its value from now on will always be the last\n * emitted value. On the other hand, if any Observable errors, `combineLatest`\n * will error immediately as well, and all other Observables will be unsubscribed.\n *\n * ## Examples\n *\n * Combine two timer Observables\n *\n * ```ts\n * import { timer, combineLatest } from 'rxjs';\n *\n * const firstTimer = timer(0, 1000); // emit 0, 1, 2... after every second, starting from now\n * const secondTimer = timer(500, 1000); // emit 0, 1, 2... after every second, starting 0,5s from now\n * const combinedTimers = combineLatest([firstTimer, secondTimer]);\n * combinedTimers.subscribe(value => console.log(value));\n * // Logs\n * // [0, 0] after 0.5s\n * // [1, 0] after 1s\n * // [1, 1] after 1.5s\n * // [2, 1] after 2s\n * ```\n *\n * Combine a dictionary of Observables\n *\n * ```ts\n * import { of, delay, startWith, combineLatest } from 'rxjs';\n *\n * const observables = {\n *   a: of(1).pipe(delay(1000), startWith(0)),\n *   b: of(5).pipe(delay(5000), startWith(0)),\n *   c: of(10).pipe(delay(10000), startWith(0))\n * };\n * const combined = combineLatest(observables);\n * combined.subscribe(value => console.log(value));\n * // Logs\n * // { a: 0, b: 0, c: 0 } immediately\n * // { a: 1, b: 0, c: 0 } after 1s\n * // { a: 1, b: 5, c: 0 } after 5s\n * // { a: 1, b: 5, c: 10 } after 10s\n * ```\n *\n * Combine an array of Observables\n *\n * ```ts\n * import { of, delay, startWith, combineLatest } from 'rxjs';\n *\n * const observables = [1, 5, 10].map(\n *   n => of(n).pipe(\n *     delay(n * 1000), // emit 0 and then emit n after n seconds\n *     startWith(0)\n *   )\n * );\n * const combined = combineLatest(observables);\n * combined.subscribe(value => console.log(value));\n * // Logs\n * // [0, 0, 0] immediately\n * // [1, 0, 0] after 1s\n * // [1, 5, 0] after 5s\n * // [1, 5, 10] after 10s\n * ```\n *\n * Use map operator to dynamically calculate the Body-Mass Index\n *\n * ```ts\n * import { of, combineLatest, map } from 'rxjs';\n *\n * const weight = of(70, 72, 76, 79, 75);\n * const height = of(1.76, 1.77, 1.78);\n * const bmi = combineLatest([weight, height]).pipe(\n *   map(([w, h]) => w / (h * h)),\n * );\n * bmi.subscribe(x => console.log('BMI is ' + x));\n *\n * // With output to console:\n * // BMI is 24.212293388429753\n * // BMI is 23.93948099205209\n * // BMI is 23.671253629592222\n * ```\n *\n * @see {@link combineLatestAll}\n * @see {@link merge}\n * @see {@link withLatestFrom}\n *\n * @param {ObservableInput} [observables] An array of input Observables to combine with each other.\n * An array of Observables must be given as the first argument.\n * @param {function} [project] An optional function to project the values from\n * the combined latest values into a new value on the output Observable.\n * @param {SchedulerLike} [scheduler=null] The {@link SchedulerLike} to use for subscribing to\n * each input Observable.\n * @return {Observable} An Observable of projected values from the most recent\n * values from each input Observable, or an array of the most recent values from\n * each input Observable.\n */\nexport function combineLatest<O extends ObservableInput<any>, R>(...args: any[]): Observable<R> | Observable<ObservedValueOf<O>[]> {\n  const scheduler = popScheduler(args);\n  const resultSelector = popResultSelector(args);\n\n  const { args: observables, keys } = argsArgArrayOrObject(args);\n\n  if (observables.length === 0) {\n    // If no observables are passed, or someone has passed an empty array\n    // of observables, or even an empty object POJO, we need to just\n    // complete (EMPTY), but we have to honor the scheduler provided if any.\n    return from([], scheduler as any);\n  }\n\n  const result = new Observable<ObservedValueOf<O>[]>(\n    combineLatestInit(\n      observables as ObservableInput<ObservedValueOf<O>>[],\n      scheduler,\n      keys\n        ? // A handler for scrubbing the array of args into a dictionary.\n          (values) => createObject(keys, values)\n        : // A passthrough to just return the array\n          identity\n    )\n  );\n\n  return resultSelector ?

As a second argument it takes string that indicates\n * type of event we want to listen for. `fromEvent` supports selected types of event targets,\n * which are described in detail below. If your event target does not match any of the ones listed,\n * you should use {@link fromEventPattern}, which can be used on arbitrary APIs.\n * When it comes to APIs supported by `fromEvent`, their methods for adding and removing event\n * handler functions have different names, but they all accept a string describing event type\n * and function itself, which will be called whenever said event happens.\n *\n * Every time resulting Observable is subscribed, event handler function will be registered\n * to event target on given event type.

In order to get access to them,\n * you can pass to `fromEvent` optional project function, which will be called with all arguments\n * passed to event handler.

It means that\n * no matter what kind of object you have and no matter what environment you work in,\n * you can safely use `fromEvent` on that object if it exposes described methods (provided\n * of course they behave as was described above). So for example if Node.js library exposes\n * event target which has the same method names as DOM EventTarget, `fromEvent` is still\n * a good choice.\n *\n * If the API you use is more callback then event handler oriented (subscribed\n * callback function fires only once and thus there is no need to manually\n * unregister it), you should use {@link bindCallback} or {@link bindNodeCallback}\n * instead.\n *\n * `fromEvent` supports following types of event targets:\n *\n * **DOM EventTarget**\n *\n * This is an object with `addEventListener` and `removeEventListener` methods.\n *\n * In the browser, `addEventListener` accepts - apart from event type string and event\n * handler function arguments - optional third parameter, which is either an object or boolean,\n * both used for additional configuration how and when passed function will be called. When\n * `fromEvent` is used with event target of that type, you can provide this values\n * as third parameter as well.\n *\n * **Node.js EventEmitter**\n *\n * An object with `addListener` and `removeListener` methods.\n *\n * **JQuery-style event target**\n *\n * An object with `on` and `off` methods\n *\n * **DOM NodeList**\n *\n * List of DOM Nodes, returned for example by `document.querySelectorAll` or `Node.childNodes`.\n *\n * Although this collection is not event target in itself, `fromEvent` will iterate over all Nodes\n * it contains and install event handler function in every of them. When returned Observable\n * is unsubscribed, function will be removed from all Nodes.\n *\n * **DOM HtmlCollection**\n *\n * Just as in case of NodeList it is a collection of DOM nodes.

It is similar to {@link fromEvent}, but far\n * more flexible. In fact, all use cases of {@link fromEvent} could be easily handled by\n * `fromEventPattern` (although in slightly more verbose way).\n *\n * This operator accepts as a first argument an `addHandler` function, which will be injected with\n * handler parameter. That handler is actually an event handler function that you now can pass\n * to API expecting it. `addHandler` will be called whenever Observable\n * returned by the operator is subscribed, so registering handler in API will not\n * necessarily happen when `fromEventPattern` is called.\n *\n * After registration, every time an event that we listen to happens,\n * Observable returned by `fromEventPattern` will emit value that event handler\n * function was called with. Note that if event handler was called with more\n * than one argument, second and following arguments will not appear in the Observable.\n *\n * If API you are using allows to unregister event handlers as well, you can pass to `fromEventPattern`\n * another function - `removeHandler` - as a second parameter. It will be injected\n * with the same handler function as before, which now you can use to unregister\n * it from the API. `removeHandler` will be called when consumer of resulting Observable\n * unsubscribes from it.\n *\n * In some APIs unregistering is actually handled differently. Method registering an event handler\n * returns some kind of token, which is later used to identify which function should\n * be unregistered or it itself has method that unregisters event handler.\n * If that is the case with your API, make sure token returned\n * by registering method is returned by `addHandler`. Then it will be passed\n * as a second argument to `removeHandler`, where you will be able to use it.\n *\n * If you need access to all event handler parameters (not only the first one),\n * or you need to transform them in any way, you can call `fromEventPattern` with optional\n * third parameter - project function which will accept all arguments passed to\n * event handler when it is called. Whatever is returned from project function will appear on\n * resulting stream instead of usual event handlers first argument. This means\n * that default project can be thought of as function that takes its first parameter\n * and ignores the rest.\n *\n * ## Examples\n *\n * Emits clicks happening on the DOM document\n *\n * ```ts\n * import { fromEventPattern } from 'rxjs';\n *\n * function addClickHandler(handler) {\n *   document.addEventListener('click', handler);\n * }\n *\n * function removeClickHandler(handler) {\n *   document.removeEventListener('click', handler);\n * }\n *\n * const clicks = fromEventPattern(\n *   addClickHandler,\n *   removeClickHandler\n * );\n * clicks.subscribe(x => console.log(x));\n *\n * // Whenever you click anywhere in the browser, DOM MouseEvent\n * // object will be logged.\n * ```\n *\n * Use with API that returns cancellation token\n *\n * ```ts\n * import { fromEventPattern } from 'rxjs';\n *\n * const token = someAPI.registerEventHandler(function() {});\n * someAPI.unregisterEventHandler(token); // this APIs cancellation method accepts\n *                                        // not handler itself, but special token.\n *\n * const someAPIObservable = fromEventPattern(\n *   function(handler) { return someAPI.registerEventHandler(handler); }, // Note that we return the token here...\n *   function(handler, token) { someAPI.unregisterEventHandler(token); }  // ...to then use it here.\n * );\n * ```\n *\n * Use with project function\n *\n * ```ts\n * import { fromEventPattern } from 'rxjs';\n *\n * someAPI.registerEventHandler((eventType, eventMessage) => {\n *   console.log(eventType, eventMessage); // Logs 'EVENT_TYPE' 'EVENT_MESSAGE' to console.\n * });\n *\n * const someAPIObservable = fromEventPattern(\n *   handler => someAPI.registerEventHandler(handler),\n *   handler => someAPI.unregisterEventHandler(handler)\n *   (eventType, eventMessage) => eventType + ' --- ' + eventMessage // without that function only 'EVENT_TYPE'\n * );                                                                // would be emitted by the Observable\n *\n * someAPIObservable.subscribe(value => console.log(value));\n *\n * // Logs:\n * // 'EVENT_TYPE --- EVENT_MESSAGE'\n * ```\n *\n * @see {@link fromEvent}\n * @see {@link bindCallback}\n * @see {@link bindNodeCallback}\n *\n * @param {function(handler: Function): any} addHandler A function that takes\n * a `handler` function as argument and attaches it somehow to the actual\n * source of events.\n * @param {function(handler: Function, token?: any): void} [removeHandler] A function that\n * takes a `handler` function as an argument and removes it from the event source.

All new subscribers will receive value emissions from a\n * new `ReplaySubject` which in turn will cause a new subscription to the source observable.\n *\n * ## Examples\n *\n * Example with a third subscriber coming late to the party\n *\n * ```ts\n * import { interval, take, shareReplay } from 'rxjs';\n *\n * const shared$ = interval(2000).pipe(\n *   take(6),\n *   shareReplay(3)\n * );\n *\n * shared$.subscribe(x => console.log('sub A: ', x));\n * shared$.subscribe(y => console.log('sub B: ', y));\n *\n * setTimeout(() => {\n *   shared$.subscribe(y => console.log('sub C: ', y));\n * }, 11000);\n *\n * // Logs:\n * // (after ~2000 ms)\n * // sub A: 0\n * // sub B: 0\n * // (after ~4000 ms)\n * // sub A: 1\n * // sub B: 1\n * // (after ~6000 ms)\n * // sub A: 2\n * // sub B: 2\n * // (after ~8000 ms)\n * // sub A: 3\n * // sub B: 3\n * // (after ~10000 ms)\n * // sub A: 4\n * // sub B: 4\n * // (after ~11000 ms, sub C gets the last 3 values)\n * // sub C: 2\n * // sub C: 3\n * // sub C: 4\n * // (after ~12000 ms)\n * // sub A: 5\n * // sub B: 5\n * // sub C: 5\n * ```\n *\n * Example for `refCount` usage\n *\n * ```ts\n * import { Observable, tap, interval, shareReplay, take } from 'rxjs';\n *\n * const log = <T>(name: string, source: Observable<T>) => source.pipe(\n *   tap({\n *     subscribe: () => console.log(`${ name }: subscribed`),\n *     next: value => console.log(`${ name }: ${ value }`),\n *     complete: () => console.log(`${ name }: completed`),\n *     finalize: () => console.log(`${ name }: unsubscribed`)\n *   })\n * );\n *\n * const obs$ = log('source', interval(1000));\n *\n * const shared$ = log('shared', obs$.pipe(\n *   shareReplay({ bufferSize: 1, refCount: true }),\n *   take(2)\n * ));\n *\n * shared$.subscribe(x => console.log('sub A: ', x));\n * shared$.subscribe(y => console.log('sub B: ', y));\n *\n * // PRINTS:\n * // shared: subscribed <-- reference count = 1\n * // source: subscribed\n * // shared: subscribed <-- reference count = 2\n * // source: 0\n * // shared: 0\n * // sub A: 0\n * // shared: 0\n * // sub B: 0\n * // source: 1\n * // shared: 1\n * // sub A: 1\n * // shared: completed <-- take(2) completes the subscription for sub A\n * // shared: unsubscribed <-- reference count = 1\n * // shared: 1\n * // sub B: 1\n * // shared: completed <-- take(2) completes the subscription for sub B\n * // shared: unsubscribed <-- reference count = 0\n * // source: unsubscribed <-- replaySubject unsubscribes from source observable because the reference count dropped to 0 and refCount is true\n *\n * // In case of refCount being false, the unsubscribe is never called on the source and the source would keep on emitting, even if no subscribers\n * // are listening.\n * // source: 2\n * // source: 3\n * // source: 4\n * // ...\n * ```\n *\n * @see {@link publish}\n * @see {@link share}\n * @see {@link publishReplay}\n *\n * @param configOrBufferSize Maximum element count of the replay buffer or {@link ShareReplayConfig configuration}\n * object.\n * @param windowTime Maximum time length of the replay buffer in milliseconds.\n * @param scheduler Scheduler where connected observers within the selector function\n * will be invoked on.\n * @return A function that returns an Observable sequence that contains the\n * elements of a sequence produced by multicasting the source sequence within a\n * selector function.\n */\nexport function shareReplay<T>(\n  configOrBufferSize?: ShareReplayConfig | number,\n  windowTime?: number,\n  scheduler?: SchedulerLike\n): MonoTypeOperatorFunction<T> {\n  let bufferSize: number;\n  let refCount = false;\n  if (configOrBufferSize && typeof configOrBufferSize === 'object') {\n    ({ bufferSize = Infinity, windowTime = Infinity, refCount = false, scheduler } = configOrBufferSize);\n  } else {\n    bufferSize = (configOrBufferSize ??

While you _could_ perform side-effects\n * inside of a `map` or a `mergeMap`, that would make their mapping functions impure, which isn't always a big deal, but will\n * make it so you can't do things like memoize those functions. The `tap` operator is designed solely for such side-effects to\n * help you remove side-effects from other operations.\n *\n * For any notification, next, error, or complete, `tap` will call the appropriate callback you have provided to it, via a function\n * reference, or a partial observer, then pass that notification down the stream.\n *\n * The observable returned by `tap` is an exact mirror of the source, with one exception: Any error that occurs -- synchronously -- in a handler\n * provided to `tap` will be emitted as an error from the returned observable.\n *\n * > Be careful! You can mutate objects as they pass through the `tap` operator's handlers.\n *\n * The most common use of `tap` is actually for debugging. You can place a `tap(console.log)` anywhere\n * in your observable `pipe`, log out the notifications as they are emitted by the source returned by the previous\n * operation.\n *\n * ## Examples\n *\n * Check a random number before it is handled. Below is an observable that will use a random number between 0 and 1,\n * and emit `'big'` or `'small'` depending on the size of that number. But we wanted to log what the original number\n * was, so we have added a `tap(console.log)`.\n *\n * ```ts\n * import { of, tap, map } from 'rxjs';\n *\n * of(Math.random()).pipe(\n *   tap(console.log),\n *   map(n => n > 0.5 ? 'big' : 'small')\n * ).subscribe(console.log);\n * ```\n *\n * Using `tap` to analyze a value and force an error. Below is an observable where in our system we only\n * want to emit numbers 3 or less we get from another source. We can force our observable to error\n * using `tap`.\n *\n * ```ts\n * import { of, tap } from 'rxjs';\n *\n * const source = of(1, 2, 3, 4, 5);\n *\n * source.pipe(\n *   tap(n => {\n *     if (n > 3) {\n *       throw new TypeError(`Value ${ n } is greater than 3`);\n *     }\n *   })\n * )\n * .subscribe({ next: console.log, error: err => console.log(err.message) });\n * ```\n *\n * We want to know when an observable completes before moving on to the next observable. The system\n * below will emit a random series of `'X'` characters from 3 different observables in sequence. The\n * only way we know when one observable completes and moves to the next one, in this case, is because\n * we have added a `tap` with the side effect of logging to console.\n *\n * ```ts\n * import { of, concatMap, interval, take, map, tap } from 'rxjs';\n *\n * of(1, 2, 3).pipe(\n *   concatMap(n => interval(1000).pipe(\n *     take(Math.round(Math.random() * 10)),\n *     map(() => 'X'),\n *     tap({ complete: () => console.log(`Done with ${ n }`) })\n *   ))\n * )\n * .subscribe(console.log);\n * ```\n *\n * @see {@link finalize}\n * @see {@link TapObserver}\n *\n * @param observerOrNext A next handler or partial observer\n * @param error An error handler\n * @param complete A completion handler\n * @return A function that returns an Observable identical to the source, but\n * runs the specified Observer or callback(s) for each item.\n */\nexport function tap<T>(\n  observerOrNext?: Partial<TapObserver<T>> | ((value: T) => void) | null,\n  error?: ((e: any) => void) | null,\n  complete?: (() => void) | null\n): MonoTypeOperatorFunction<T> {\n  // We have to check to see not only if next is a function,\n  // but if error or complete were passed.

It\n   * might be for example a function that you passed to Observable's constructor, but most of the time it is\n   * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n   * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n   * the thought.\n   *\n   * Apart from starting the execution of an Observable, this method allows you to listen for values\n   * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n   * of the following ways.\n   *\n   * The first way is creating an object that implements {@link Observer} interface. It should have methods\n   * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n   * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n   * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n   * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n   * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n   * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n   * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n   * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n   * an `error` method to avoid missing thrown errors.\n   *\n   * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n   * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n   * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n   * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n   * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n   * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n   *\n   * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n   * and you also handled emissions internally by using operators (e.g. using `tap`).\n   *\n   * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n   * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n   * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n   * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n   *\n   * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n   * It is an Observable itself that decides when these functions will be called. For example {@link of}\n   * by default emits all its values synchronously. Always check documentation for how given Observable\n   * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n   *\n   * #### Examples\n   *\n   * Subscribe with an {@link guide/observer Observer}\n   *\n   * ```ts\n   * import { of } from 'rxjs';\n   *\n   * const sumObserver = {\n   *   sum: 0,\n   *   next(value) {\n   *     console.log('Adding: ' + value);\n   *     this.sum = this.sum + value;\n   *   },\n   *   error() {\n   *     // We actually could just remove this method,\n   *     // since we do not really care about errors right now.\n   *   },\n   *   complete() {\n   *     console.log('Sum equals: ' + this.sum);\n   *   }\n   * };\n   *\n   * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n   *   .subscribe(sumObserver);\n   *\n   * // Logs:\n   * // 'Adding: 1'\n   * // 'Adding: 2'\n   * // 'Adding: 3'\n   * // 'Sum equals: 6'\n   * ```\n   *\n   * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n   *\n   * ```ts\n   * import { of } from 'rxjs'\n   *\n   * let sum = 0;\n   *\n   * of(1, 2, 3).subscribe(\n   *   value => {\n   *     console.log('Adding: ' + value);\n   *     sum = sum + value;\n   *   },\n   *   undefined,\n   *   () => console.log('Sum equals: ' + sum)\n   * );\n   *\n   * // Logs:\n   * // 'Adding: 1'\n   * // 'Adding: 2'\n   * // 'Adding: 3'\n   * // 'Sum equals: 6'\n   * ```\n   *\n   * Cancel a subscription\n   *\n   * ```ts\n   * import { interval } from 'rxjs';\n   *\n   * const subscription = interval(1000).subscribe({\n   *   next(num) {\n   *     console.log(num)\n   *   },\n   *   complete() {\n   *     // Will not be called, even when cancelling subscription.\n   *     console.log('completed!');\n   *   }\n   * });\n   *\n   * setTimeout(() => {\n   *   subscription.unsubscribe();\n   *   console.log('unsubscribed!');\n   * }, 2500);\n   *\n   * // Logs:\n   * // 0 after 1s\n   * // 1 after 2s\n   * // 'unsubscribed!' after 2.5s\n   * ```\n   *\n   * @param {Observer|Function} observerOrNext (optional) Either an observer with methods to be called,\n   * or the first of three possible handlers, which is the handler for each value emitted from the subscribed\n   * Observable.\n   * @param {Function} error (optional) A handler for a terminal event resulting from an error.

It might be useful, if you do not have control over\n * internal scheduler of a given Observable, but want to control when its values are emitted nevertheless.\n *\n * Returned Observable emits the same notifications (nexted values, complete and error events) as the source Observable,\n * but rescheduled with provided scheduler. Note that this doesn't mean that source Observables internal\n * scheduler will be replaced in any way. Original scheduler still will be used, but when the source Observable emits\n * notification, it will be immediately scheduled again - this time with scheduler passed to `observeOn`.\n * An anti-pattern would be calling `observeOn` on Observable that emits lots of values synchronously, to split\n * that emissions into asynchronous chunks. For this to happen, scheduler would have to be passed into the source\n * Observable directly (usually into the operator that creates it). `observeOn` simply delays notifications a\n * little bit more, to ensure that they are emitted at expected moments.\n *\n * As a matter of fact, `observeOn` accepts second parameter, which specifies in milliseconds with what delay notifications\n * will be emitted. The main difference between {@link delay} operator and `observeOn` is that `observeOn`\n * will delay all notifications - including error notifications - while `delay` will pass through error\n * from source Observable immediately when it is emitted. In general it is highly recommended to use `delay` operator\n * for any kind of delaying of values in the stream, while using `observeOn` to specify which scheduler should be used\n * for notification emissions in general.\n *\n * ##

This is done by subscribing to each Observable in order and,\n * whenever any Observable emits, collecting an array of the most recent\n * values from each Observable. So if you pass `n` Observables to this operator,\n * the returned Observable will always emit an array of `n` values, in an order\n * corresponding to the order of the passed Observables (the value from the first Observable\n * will be at index 0 of the array and so on).\n *\n * Static version of `combineLatest` accepts an array of Observables. Note that an array of\n * Observables is a good choice, if you don't know beforehand how many Observables\n * you will combine. Passing an empty array will result in an Observable that\n * completes immediately.\n *\n * To ensure the output array always has the same length, `combineLatest` will\n * actually wait for all input Observables to emit at least once,\n * before it starts emitting results. This means if some Observable emits\n * values before other Observables started emitting, all these values but the last\n * will be lost. On the other hand, if some Observable does not emit a value but\n * completes, resulting Observable will complete at the same moment without\n * emitting anything, since it will now be impossible to include a value from the\n * completed Observable in the resulting array. Also, if some input Observable does\n * not emit any value and never completes, `combineLatest` will also never emit\n * and never complete, since, again, it will wait for all streams to emit some\n * value.\n *\n * If at least one Observable was passed to `combineLatest` and all passed Observables\n * emitted something, the resulting Observable will complete when all combined\n * streams complete.

As a second argument it takes string that indicates\n * type of event we want to listen for. `fromEvent` supports selected types of event targets,\n * which are described in detail below. If your event target does not match any of the ones listed,\n * you should use {@link fromEventPattern}, which can be used on arbitrary APIs.\n * When it comes to APIs supported by `fromEvent`, their methods for adding and removing event\n * handler functions have different names, but they all accept a string describing event type\n * and function itself, which will be called whenever said event happens.\n *\n * Every time resulting Observable is subscribed, event handler function will be registered\n * to event target on given event type. When that event fires, value\n * passed as a first argument to registered function will be emitted by output Observable.\n * When Observable is unsubscribed, function will be unregistered from event target.\n *\n * Note that if event target calls registered function with more than one argument, second\n * and following arguments will not appear in resulting stream. In order to get access to them,\n * you can pass to `fromEvent` optional project function, which will be called with all arguments\n * passed to event handler. Output Observable will then emit value returned by project function,\n * instead of the usual value.\n *\n * Remember that event targets listed below are checked via duck typing. It means that\n * no matter what kind of object you have and no matter what environment you work in,\n * you can safely use `fromEvent` on that object if it exposes described methods (provided\n * of course they behave as was described above). So for example if Node.js library exposes\n * event target which has the same method names as DOM EventTarget, `fromEvent` is still\n * a good choice.\n *\n * If the API you use is more callback then event handler oriented (subscribed\n * callback function fires only once and thus there is no need to manually\n * unregister it), you should use {@link bindCallback} or {@link bindNodeCallback}\n * instead.\n *\n * `fromEvent` supports following types of event targets:\n *\n * **DOM EventTarget**\n *\n * This is an object with `addEventListener` and `removeEventListener` methods.\n *\n * In the browser, `addEventListener` accepts - apart from event type string and event\n * handler function arguments - optional third parameter, which is either an object or boolean,\n * both used for additional configuration how and when passed function will be called. When\n * `fromEvent` is used with event target of that type, you can provide this values\n * as third parameter as well.\n *\n * **Node.js EventEmitter**\n *\n * An object with `addListener` and `removeListener` methods.\n *\n * **JQuery-style event target**\n *\n * An object with `on` and `off` methods\n *\n * **DOM NodeList**\n *\n * List of DOM Nodes, returned for example by `document.querySelectorAll` or `Node.childNodes`.\n *\n * Although this collection is not event target in itself, `fromEvent` will iterate over all Nodes\n * it contains and install event handler function in every of them. When returned Observable\n * is unsubscribed, function will be removed from all Nodes.\n *\n * **DOM HtmlCollection**\n *\n * Just as in case of NodeList it is a collection of DOM nodes. Here as well event handler function is\n * installed and removed in each of elements.\n *\n *\n * ## Examples\n *\n * Emit clicks happening on the DOM document\n *\n * ```ts\n * import { fromEvent } from 'rxjs';\n *\n * const clicks = fromEvent(document, 'click');\n * clicks.subscribe(x => console.log(x));\n *\n * // Results in:\n * // MouseEvent object logged to console every time a click\n * // occurs on the document.\n * ```\n *\n * Use `addEventListener` with capture option\n *\n * ```ts\n * import { fromEvent } from 'rxjs';\n *\n * const div = document.createElement('div');\n * div.style.cssText = 'width: 200px; height: 200px; background: #09c;';\n * document.body.appendChild(div);\n *\n * // note optional configuration parameter which will be passed to addEventListener\n * const clicksInDocument = fromEvent(document, 'click', { capture: true });\n * const clicksInDiv = fromEvent(div, 'click');\n *\n * clicksInDocument.subscribe(() => console.log('document'));\n * clicksInDiv.subscribe(() => console.log('div'));\n *\n * // By default events bubble UP in DOM tree, so normally\n * // when we would click on div in document\n * // \"div\" would be logged first and then \"document\".\n * // Since we specified optional `capture` option, document\n * // will catch event when it goes DOWN DOM tree, so console\n * // will log \"document\" and then \"div\".\n * ```\n *\n * @see {@link bindCallback}\n * @see {@link bindNodeCallback}\n * @see {@link fromEventPattern}\n *\n * @param {FromEventTarget<T>} target The DOM EventTarget, Node.js\n * EventEmitter, JQuery-like event target, NodeList or HTMLCollection to attach the event handler to.\n * @param {string} eventName The event name of interest, being emitted by the\n * `target`.\n * @param {EventListenerOptions} [options] Options to pass through to addEventListener\n * @return {Observable<T>}\n */\nexport function fromEvent<T>(\n  target: any,\n  eventName: string,\n  options?: EventListenerOptions | ((...args: any[]) => T),\n  resultSelector?: (...args: any[]) => T\n): Observable<T> {\n  if (isFunction(options)) {\n    resultSelector = options;\n    options = undefined;\n  }\n  if (resultSelector) {\n    return fromEvent<T>(target, eventName, options as EventListenerOptions).pipe(mapOneOrManyArgs(resultSelector));\n  }\n\n  // Figure out our add and remove methods.

In fact, all use cases of {@link fromEvent} could be easily handled by\n * `fromEventPattern` (although in slightly more verbose way).\n *\n * This operator accepts as a first argument an `addHandler` function, which will be injected with\n * handler parameter. That handler is actually an event handler function that you now can pass\n * to API expecting it. `addHandler` will be called whenever Observable\n * returned by the operator is subscribed, so registering handler in API will not\n * necessarily happen when `fromEventPattern` is called.\n *\n * After registration, every time an event that we listen to happens,\n * Observable returned by `fromEventPattern` will emit value that event handler\n * function was called with. Note that if event handler was called with more\n * than one argument, second and following arguments will not appear in the Observable.\n *\n * If API you are using allows to unregister event handlers as well, you can pass to `fromEventPattern`\n * another function - `removeHandler` - as a second parameter. It will be injected\n * with the same handler function as before, which now you can use to unregister\n * it from the API. `removeHandler` will be called when consumer of resulting Observable\n * unsubscribes from it.\n *\n * In some APIs unregistering is actually handled differently. Method registering an event handler\n * returns some kind of token, which is later used to identify which function should\n * be unregistered or it itself has method that unregisters event handler.\n * If that is the case with your API, make sure token returned\n * by registering method is returned by `addHandler`. Then it will be passed\n * as a second argument to `removeHandler`, where you will be able to use it.\n *\n * If you need access to all event handler parameters (not only the first one),\n * or you need to transform them in any way, you can call `fromEventPattern` with optional\n * third parameter - project function which will accept all arguments passed to\n * event handler when it is called. Whatever is returned from project function will appear on\n * resulting stream instead of usual event handlers first argument.

Use {@link retry} for that.\n *\n * - `repeat(0)` returns an empty observable\n * - `repeat()` will repeat forever\n * - `repeat({ delay: 200 })` will repeat forever, with a delay of 200ms between repetitions.\n * - `repeat({ count: 2, delay: 400 })` will repeat twice, with a delay of 400ms between repetitions.\n * - `repeat({ delay: (count) => timer(count * 1000) })` will repeat forever, but will have a delay that grows by one second for each repetition.\n *\n * ## Example\n *\n * Repeat a message stream\n *\n * ```ts\n * import { of, repeat } from 'rxjs';\n *\n * const source = of('Repeat message');\n * const result = source.pipe(repeat(3));\n *\n * result.subscribe(x => console.log(x));\n *\n * // Results\n * // 'Repeat message'\n * // 'Repeat message'\n * // 'Repeat message'\n * ```\n *\n * Repeat 3 values, 2 times\n *\n * ```ts\n * import { interval, take, repeat } from 'rxjs';\n *\n * const source = interval(1000);\n * const result = source.pipe(take(3), repeat(2));\n *\n * result.subscribe(x => console.log(x));\n *\n * // Results every second\n * // 0\n * // 1\n * // 2\n * // 0\n * // 1\n * // 2\n * ```\n *\n * Defining two complex repeats with delays on the same source.\n * Note that the second repeat cannot be called until the first\n * repeat as exhausted it's count.\n *\n * ```ts\n * import { defer, of, repeat } from 'rxjs';\n *\n * const source = defer(() => {\n *    return of(`Hello, it is ${new Date()}`)\n * });\n *\n * source.pipe(\n *    // Repeat 3 times with a delay of 1 second between repetitions\n *    repeat({\n *      count: 3,\n *      delay: 1000,\n *    }),\n *\n *    // *Then* repeat forever, but with an exponential step-back\n *    // maxing out at 1 minute.\n *    repeat({\n *      delay: (count) => timer(Math.min(60000, 2 ^ count * 1000))\n *    })\n * )\n * ```\n *\n * @see {@link repeatWhen}\n * @see {@link retry}\n *\n * @param count The number of times the source Observable items are repeated, a count of 0 will yield\n * an empty Observable.\n */\nexport function repeat<T>(countOrConfig?: number | RepeatConfig): MonoTypeOperatorFunction<T> {\n  let count = Infinity;\n  let delay: RepeatConfig['delay'];\n\n  if (countOrConfig != null) {\n    if (typeof countOrConfig === 'object') {\n      ({ count = Infinity, delay } = countOrConfig);\n    } else {\n      count = countOrConfig;\n    }\n  }\n\n  return count <= 0\n    ?

All new subscribers will receive value emissions from a\n * new `ReplaySubject` which in turn will cause a new subscription to the source observable.\n *\n * ## Examples\n *\n * Example with a third subscriber coming late to the party\n *\n * ```ts\n * import { interval, take, shareReplay } from 'rxjs';\n *\n * const shared$ = interval(2000).pipe(\n *   take(6),\n *   shareReplay(3)\n * );\n *\n * shared$.subscribe(x => console.log('sub A: ', x));\n * shared$.subscribe(y => console.log('sub B: ', y));\n *\n * setTimeout(() => {\n *   shared$.subscribe(y => console.log('sub C: ', y));\n * }, 11000);\n *\n * // Logs:\n * // (after ~2000 ms)\n * // sub A: 0\n * // sub B: 0\n * // (after ~4000 ms)\n * // sub A: 1\n * // sub B: 1\n * // (after ~6000 ms)\n * // sub A: 2\n * // sub B: 2\n * // (after ~8000 ms)\n * // sub A: 3\n * // sub B: 3\n * // (after ~10000 ms)\n * // sub A: 4\n * // sub B: 4\n * // (after ~11000 ms, sub C gets the last 3 values)\n * // sub C: 2\n * // sub C: 3\n * // sub C: 4\n * // (after ~12000 ms)\n * // sub A: 5\n * // sub B: 5\n * // sub C: 5\n * ```\n *\n * Example for `refCount` usage\n *\n * ```ts\n * import { Observable, tap, interval, shareReplay, take } from 'rxjs';\n *\n * const log = <T>(name: string, source: Observable<T>) => source.pipe(\n *   tap({\n *     subscribe: () => console.log(`${ name }: subscribed`),\n *     next: value => console.log(`${ name }: ${ value }`),\n *     complete: () => console.log(`${ name }: completed`),\n *     finalize: () => console.log(`${ name }: unsubscribed`)\n *   })\n * );\n *\n * const obs$ = log('source', interval(1000));\n *\n * const shared$ = log('shared', obs$.pipe(\n *   shareReplay({ bufferSize: 1, refCount: true }),\n *   take(2)\n * ));\n *\n * shared$.subscribe(x => console.log('sub A: ', x));\n * shared$.subscribe(y => console.log('sub B: ', y));\n *\n * // PRINTS:\n * // shared: subscribed <-- reference count = 1\n * // source: subscribed\n * // shared: subscribed <-- reference count = 2\n * // source: 0\n * // shared: 0\n * // sub A: 0\n * // shared: 0\n * // sub B: 0\n * // source: 1\n * // shared: 1\n * // sub A: 1\n * // shared: completed <-- take(2) completes the subscription for sub A\n * // shared: unsubscribed <-- reference count = 1\n * // shared: 1\n * // sub B: 1\n * // shared: completed <-- take(2) completes the subscription for sub B\n * // shared: unsubscribed <-- reference count = 0\n * // source: unsubscribed <-- replaySubject unsubscribes from source observable because the reference count dropped to 0 and refCount is true\n *\n * // In case of refCount being false, the unsubscribe is never called on the source and the source would keep on emitting, even if no subscribers\n * // are listening.\n * // source: 2\n * // source: 3\n * // source: 4\n * // ...\n * ```\n *\n * @see {@link publish}\n * @see {@link share}\n * @see {@link publishReplay}\n *\n * @param configOrBufferSize Maximum element count of the replay buffer or {@link ShareReplayConfig configuration}\n * object.\n * @param windowTime Maximum time length of the replay buffer in milliseconds.\n * @param scheduler Scheduler where connected observers within the selector function\n * will be invoked on.\n * @return A function that returns an Observable sequence that contains the\n * elements of a sequence produced by multicasting the source sequence within a\n * selector function.\n */\nexport function shareReplay<T>(\n  configOrBufferSize?: ShareReplayConfig | number,\n  windowTime?: number,\n  scheduler?: SchedulerLike\n): MonoTypeOperatorFunction<T> {\n  let bufferSize: number;\n  let refCount = false;\n  if (configOrBufferSize && typeof configOrBufferSize === 'object') {\n    ({ bufferSize = Infinity, windowTime = Infinity, refCount = false, scheduler } = configOrBufferSize);\n  } else {\n    bufferSize = (configOrBufferSize ??

While you _could_ perform side-effects\n * inside of a `map` or a `mergeMap`, that would make their mapping functions impure, which isn't always a big deal, but will\n * make it so you can't do things like memoize those functions. The `tap` operator is designed solely for such side-effects to\n * help you remove side-effects from other operations.\n *\n * For any notification, next, error, or complete, `tap` will call the appropriate callback you have provided to it, via a function\n * reference, or a partial observer, then pass that notification down the stream.\n *\n * The observable returned by `tap` is an exact mirror of the source, with one exception: Any error that occurs -- synchronously -- in a handler\n * provided to `tap` will be emitted as an error from the returned observable.\n *\n * > Be careful! You can mutate objects as they pass through the `tap` operator's handlers.\n *\n * The most common use of `tap` is actually for debugging. You can place a `tap(console.log)` anywhere\n * in your observable `pipe`, log out the notifications as they are emitted by the source returned by the previous\n * operation.\n *\n * ## Examples\n *\n * Check a random number before it is handled. Below is an observable that will use a random number between 0 and 1,\n * and emit `'big'` or `'small'` depending on the size of that number. But we wanted to log what the original number\n * was, so we have added a `tap(console.log)`.\n *\n * ```ts\n * import { of, tap, map } from 'rxjs';\n *\n * of(Math.random()).pipe(\n *   tap(console.log),\n *   map(n => n > 0.5 ? 'big' : 'small')\n * ).subscribe(console.log);\n * ```\n *\n * Using `tap` to analyze a value and force an error. Below is an observable where in our system we only\n * want to emit numbers 3 or less we get from another source. We can force our observable to error\n * using `tap`.\n *\n * ```ts\n * import { of, tap } from 'rxjs';\n *\n * const source = of(1, 2, 3, 4, 5);\n *\n * source.pipe(\n *   tap(n => {\n *     if (n > 3) {\n *       throw new TypeError(`Value ${ n } is greater than 3`);\n *     }\n *   })\n * )\n * .subscribe({ next: console.log, error: err => console.log(err.message) });\n * ```\n *\n * We want to know when an observable completes before moving on to the next observable. The system\n * below will emit a random series of `'X'` characters from 3 different observables in sequence. The\n * only way we know when one observable completes and moves to the next one, in this case, is because\n * we have added a `tap` with the side effect of logging to console.\n *\n * ```ts\n * import { of, concatMap, interval, take, map, tap } from 'rxjs';\n *\n * of(1, 2, 3).pipe(\n *   concatMap(n => interval(1000).pipe(\n *     take(Math.round(Math.random() * 10)),\n *     map(() => 'X'),\n *     tap({ complete: () => console.log(`Done with ${ n }`) })\n *   ))\n * )\n * .subscribe(console.log);\n * ```\n *\n * @see {@link finalize}\n * @see {@link TapObserver}\n *\n * @param observerOrNext A next handler or partial observer\n * @param error An error handler\n * @param complete A completion handler\n * @return A function that returns an Observable identical to the source, but\n * runs the specified Observer or callback(s) for each item.\n */\nexport function tap<T>(\n  observerOrNext?: Partial<TapObserver<T>> | ((value: T) => void) | null,\n  error?: ((e: any) => void) | null,\n  complete?: (() => void) | null\n): MonoTypeOperatorFunction<T> {\n  // We have to check to see not only if next is a function,\n  // but if error or complete were passed.

For a term's presence to be required in a document the\n * term should be prefixed with a '+', e.g. `+foo bar` is a search for documents that must contain 'foo' and\n * optionally contain 'bar'. Conversely a leading '-' sets the terms presence to prohibited, i.e. it must not\n * appear in a document, e.g. `-foo bar` is a search for documents that do not contain 'foo' but may contain 'bar'.\n *\n * To escape special characters the backslash character '\\' can be used, this allows searches to include\n * characters that would normally be considered modifiers, e.g. `foo\\~2` will search for a term \"foo~2\" instead\n * of attempting to apply a boost of 2 to the search term \"foo\".\n *\n * @typedef {string} lunr.Index~QueryString\n * @example <caption>Simple single term query</caption>\n * hello\n * @example <caption>Multiple term query</caption>\n * hello world\n * @example <caption>term scoped to a field</caption>\n * title:hello\n * @example <caption>term with a boost of 10</caption>\n * hello^10\n * @example <caption>term with an edit distance of 2</caption>\n * hello~2\n * @example <caption>terms with presence modifiers</caption>\n * -foo +bar baz\n */\n\n/**\n * Performs a search against the index using lunr query syntax.\n *\n * Results will be returned sorted by their score, the most relevant results\n * will be returned first.

For a term's presence to be required in a document the\n * term should be prefixed with a '+', e.g. `+foo bar` is a search for documents that must contain 'foo' and\n * optionally contain 'bar'. Conversely a leading '-' sets the terms presence to prohibited, i.e. it must not\n * appear in a document, e.g. `-foo bar` is a search for documents that do not contain 'foo' but may contain 'bar'.\n *\n * To escape special characters the backslash character '\\' can be used, this allows searches to include\n * characters that would normally be considered modifiers, e.g. `foo\\~2` will search for a term \"foo~2\" instead\n * of attempting to apply a boost of 2 to the search term \"foo\".\n *\n * @typedef {string} lunr.Index~QueryString\n * @example <caption>Simple single term query</caption>\n * hello\n * @example <caption>Multiple term query</caption>\n * hello world\n * @example <caption>term scoped to a field</caption>\n * title:hello\n * @example <caption>term with a boost of 10</caption>\n * hello^10\n * @example <caption>term with an edit distance of 2</caption>\n * hello~2\n * @example <caption>terms with presence modifiers</caption>\n * -foo +bar baz\n */\n\n/**\n * Performs a search against the index using lunr query syntax.\n *\n * Results will be returned sorted by their score, the most relevant results\n * will be returned first.

The CLI can be used to create a docker-compose environment that runs the entirety of a FireFly network. This will include several different processes for each member of the network. This is very useful for people that want to build apps that use FireFly's API. It can also be useful if you want to make changes to FireFly itself, however we need to set up the stack slightly differently in that case.</p> <p>Essentially what we are going to do is have docker-compose run everything in the FireFly network except one FireFly core process. We'll run this FireFly core process on our host machine, and configure it to connect to the rest of the microservices running in docker-compose. This means we could launch FireFly from Visual Studio Code or some other IDE and use a debugger to see what's going on inside FireFly as it's running.</p> <p>We'll call this stack <code>dev</code>. We're also going to add <code>--external 1</code> to the end of our command to create the new stack:</p> <pre><code>ff init dev --external 1\n</code></pre> <p>This tells the CLI that we want to manage one of the FireFly core processes outside the docker-compose stack.

If you run FireFly from the <code>firefly</code> project directory you cloned from GitHub, it will automatically find these and apply them.

By default, most EVM clients do not store this reason in the transaction receipt. This is typically to reduce resource consumption such as memory usage in the client. It is usually possible to configure an EVM client to store the revert reason in the transaction receipt. For example Hyperledger Besu\u2122 provides the <code>--revert-reason-enabled</code> configuration option. If the transaction receipt does not contain the revert reason it is possible to request that an EVM client re-run the transaction and return a trace of all of the op-codes, including the final <code>REVERT</code> <code>REASON</code>.

In order to move from <code>Received</code> to <code>Tracking</code> several actions were performed: <code>AssignNonce</code>, <code>RetrieveGasPrice</code>, and <code>SubmitTransaction</code>.</p>"},{"location":"reference/blockchain_operation_status/#history-example","title":"History Example","text":"<pre><code>{\n    ...\n    \"lastSubmit\": \"2023-01-27T17:11:41.222375469Z\",\n    \"nonce\": \"14\",\n    \"history\": [\n        {\n            \"subStatus\": \"Received\",\n            \"time\": \"2023-01-27T17:11:41.122965803Z\",\n            \"actions\": [\n                {\n                    \"action\": \"AssignNonce\",\n                    \"count\": 1,\n                    \"lastInfo\": {\n   \u2003                    \"nonce\": \"14\"\n                    },\n                    \"lastOccurrence\": \"2023-01-27T17:11:41.122967219Z\",\n                    \"time\": \"2023-01-27T17:11:41.122967136Z\"\n                },\n   \u2003            {\n                    \"action\": \"RetrieveGasPrice\",\n                    \"count\": 1,\n                    \"lastInfo\": {\n                        \"gasPrice\": \"0\"\n                    },\n                    \"lastOccurrence\": \"2023-01-27T17:11:41.161213303Z\",\n                    \"time\": \"2023-01-27T17:11:41.161213094Z\"\n                },\n                {\n                    \"action\": \"SubmitTransaction\",\n                    \"count\": 1,\n   \u2003                \"lastInfo\": {\n                        \"txHash\": \"0x4c37de1cf320a1d5c949082bbec8ad5fe918e6621cec3948d609ec3f7deac243\"\n                    },\n   \u2003                \"lastOccurrence\": \"2023-01-27T17:11:41.222374636Z\",\n   \u2003                \"time\": \"2023-01-27T17:11:41.222374553Z\"\n   \u2003            }\n   \u2003        ],\n  \u2003     },\n \u2003      {\n \u2003\u2003         \"subStatus\": \"Tracking\",\n            \"time\": \"2023-01-27T17:11:41.222400219Z\",\n    \u2003       \"actions\": [\n   \u2003\u2003\u2003          {\n    \u2003\u2003\u2003\u2003            \"action\": \"ReceiveReceipt\",\n     \u2003\u2003\u2003\u2003           \"count\": 2,\n    \u2003\u2003\u2003\u2003            \"lastInfo\": {\n     \u2003\u2003\u2003\u2003\u2003              \"protocolId\": \"000001265122/000000\"\n    \u2003\u2003\u2003\u2003            },\n    \u2003\u2003\u2003\u2003            \"lastOccurrence\": \"2023-01-27T17:11:57.93120838Z\",\n    \u2003\u2003\u2003\u2003            \"time\": \"2023-01-27T17:11:47.930332625Z\"\n   \u2003\u2003\u2003          },\n   \u2003\u2003\u2003          {\n   \u2003\u2003\u2003\u2003             \"action\": \"Confirm\",\n    \u2003\u2003\u2003\u2003            \"count\": 1,\n    \u2003\u2003\u2003\u2003            \"lastOccurrence\": \"2023-01-27T17:12:02.660275549Z\",\n    \u2003\u2003\u2003\u2003            \"time\": \"2023-01-27T17:12:02.660275382Z\"\n    \u2003\u2003\u2003         }\n   \u2003\u2003       ],\n  \u2003     },\n  \u2003     {\n \u2003\u2003         \"subStatus\": \"Confirmed\",\n  \u2003\u2003        \"time\": \"2023-01-27T17:12:02.660309382Z\",\n  \u2003\u2003        \"actions\": [],\n  \u2003     }\n    ]\n    ...\n}\n</code></pre> <p>Because the <code>history</code> field is a FIFO structure describing the N most recent sub-status changes, some early sub-status changes or actions may be lost over time.

After upgrading to the latest v1.0.x patch release, you should therefore look for any deprecation warnings when starting FireFly, and ensure they are fixed before upgrading to v1.1.0.

FireFly v1.0 allowed for the dynamic creation of new namespaces by broadcasting a namespace definition to all nodes. This functionality is _removed_ in v1.1.0. If your network relies on any namespaces that were created via a broadcast, you must add those namespaces to the `namespaces.predefined` list in your YAML config prior to upgrade. If you do not, they will cease to function after upgrading to v1.1.0 (all events on those namespaces will be ignored by your node).   <p>Identify queries for organization/node identities</p> Expand for migration details only if your application queries <code>/network/organizations</code> or <code>/network/nodes</code>.  Applications that query `/network/organizations` or `/network/nodes` will temporarily receive _empty result lists_ after upgrading to v1.1.0, just until all identities have been re-registered (see steps in \"After Upgrading\"). This is because organization and node identities were broadcast on a global \"ff_system\" namespace in v1.0, but are no longer global in v1.1.0.  The simplest solution is to shut down applications until the FireFly upgrade is complete on all nodes and all identities have been re-broadcast.  If this poses a problem and you require zero downtime from these APIs, you can proactively mitigate with the following steps in your application code:  - Applications that query the `/network/organizations` may be altered to _also_ query `/namespaces/ff_system/network/organizations` and combine the results (but should disregard the second query if it fails). - Applications that query the `/network/nodes` may be altered to _also_ query `/namespaces/ff_system/network/nodes` and combine the results (but should disregard the second query if it fails).  Further details on the changes to `/network` APIs are provided in the next section.   <p>Identify usage of changed APIs</p> Expand for migration details on all changes to <code>/namespaces</code>, <code>/status</code>, and <code>/network</code> APIs.  The primary API change in this version is that the \"global\" paths beginning with `/network` and `/status` have been relocated under the `/namespaces/{ns}` prefix, as this data is now specific to a namespace instead of being global. At the same time, the API server has been enhanced so that omitting a namespace from an API path will _query the default namespace_ instead. That is, querying `/messages` is now the same as querying `/namespaces/default/messages` (assuming your default namespace is named \"default\"). This has the effect that most of the moved APIs will continue to function without requiring changes. See below for details on the affected paths.  These global routes have been moved under `/namespaces/{ns}`. Continuing to use them without the namespace prefix **will still work**, and will simply query the default namespace.  <pre><code>/network/diddocs/{did}\n/network/nodes\n/network/nodes/{nameOrId}\n/network/nodes/self\n/network/organizations\n/network/organizations/{nameOrId}\n/network/organizations/self\n/status\n/status/batchmanager\n</code></pre>  These global routes have been moved under `/namespaces/{ns}` and have also been deprecated in favor of a new route name. Continuing to use them without the namespace prefix **will still work**, and will simply query the default namespace. However, it is recommended to switch to the new API spelling when possible.  <pre><code>/network/identities - replaced by existing /namespaces/{ns}/identities\n/network/identities/{did} - replaced by new /namespaces/{ns}/identities/{did}\n</code></pre>  These global routes have been have been permanently renamed. They are deemed less likely to be used by client applications, but any usage **will be broken** by this release and must be changed after upgrading.  <pre><code>/status/pins - moved to /namespaces/{ns}/pins (or /pins to query the default namespace)\n/status/websockets - moved to /websockets\n</code></pre>  The response bodies of the following APIs have also had fields removed. Any usage of the removed fields **will be broken** by this release and must be changed after upgrading.  <pre><code>/namespaces - removed all fields except \"name\", \"description\", \"created\"\n/namespaces/{ns} - same as above\n/namespaces/{ns}/status - removed \"defaults\"\n</code></pre> <p>Adjust or remove usage of admin APIs</p> Expand for migration details on all changes to <code>/admin</code> and <code>/spi</code>.  FireFly provides an administrative API in addition to the normal API. In v1.1.0, this has been renamed to SPI (Service Provider Interface). Consequently, all of the routes have moved from `/admin` to `/spi`, and the config section has been renamed from `admin` to `spi`. There is no automatic migration provided, so any usage of the old routes will need to be changed, and your config file will need to be adjusted if you wish to keep the SPI enabled (although it is perfectly fine to have both `admin` and `spi` sections if needed for migration).  The ability to set FireFly config via these routes has also been removed. Any usage of the `/admin/config` routes must be discontinued, and config should be set exclusively by editing the FireFly config file. The only route retained from this functionality was `/admin/config/reset`, which has been renamed to `/spi/reset` - this will continue to be available for performing a soft reset that reloads FireFly's config."},{"location":"releasenotes/1.1_migration_guide/#performing-the-upgrade","title":"Performing the Upgrade","text":"<p>Backup current data</p> <p>Before beginning the upgrade, it is recommended to take a full backup of your FireFly database(s).

However, this is an advanced use case and you are likely to set a single topic on the vast majority of your messages.</p>"},{"location":"tutorials/broadcast_data/#example-3-upload-a-blob-with-metadata-and-broadcast","title":"Example 3: Upload a blob with metadata and broadcast","text":"<p>Here we make two API calls.</p> <ol> <li> <p>Create the <code>data</code> object explicitly, using a multi-part form upload</p> </li> <li> <p>You can also just post JSON to this endpoint</p> </li> <li> <p>Broadcast a message referring to that data</p> </li> <li> <p>The Blob attachment gets published to shared storage</p> </li> <li>This happens the first time a broadcast happens on a data attachment</li> <li>A pin goes to the blockchain</li> <li>The metadata goes into a batch with the message</li> </ol>"},{"location":"tutorials/broadcast_data/#multipart-form-post-of-a-file","title":"Multipart form post of a file","text":"<p>Example curl command (Linux/Mac) to grab an image from the internet, and pipe it into a multi-part form post to FireFly.</p> <p>Note we use <code>autometa</code> to cause FireFly to automatically add the <code>filename</code>, and <code>size</code>, to the JSON part of the <code>data</code> object for us.</p> <pre><code>curl -sLo - https://github.com/hyperledger/firefly/raw/main/docs/firefly_logo.png \\\n | curl --form autometa=true --form file=@- \\\n   http://localhost:5000/api/v1/namespaces/default/data\n</code></pre>"},{"location":"tutorials/broadcast_data/#example-data-response-from-blob-upload","title":"Example data response from Blob upload","text":"<p>Status: <code>200 OK</code> - your data is uploaded to your local FireFly node</p> <p>At this point the data has not be shared with anyone else in the network</p> <pre><code>{\n  // A uniquely generated ID, we can refer to when sending this data to other parties\n  \"id\": \"97eb750f-0d0b-4c1d-9e37-1e92d1a22bb8\",\n  \"validator\": \"json\", // the \"value\" part is JSON\n  \"namespace\": \"default\", // from the URL\n  // The hash is a combination of the hash of the \"value\" metadata, and the\n  // hash of the blob\n  \"hash\": \"997af6a9a19f06cc8a46872617b8bf974b106f744b2e407e94cc6959aa8cf0b8\",\n  \"created\": \"2021-07-01T20:20:35.5462306Z\",\n  \"value\": {\n    \"filename\": \"-\", // dash is how curl represents the filename for stdin\n    \"size\": 31185 // the size of the blob data\n  },\n  \"blob\": {\n    // A hash reference to the blob\n    \"hash\": \"86e6b39b04b605dd1b03f70932976775962509d29ae1ad2628e684faabe48136\"\n    // Note at this point there is no public reference.

This is referred to as a Contract Interface. A contract interface is written in the FireFly Interface (FFI) format. It is a simple JSON document that has a name, a namespace, a version, a list of methods, and a list of events.</li> </ul> <p>For more details, you can also have a look at the Reference page for the FireFly Interface Format.</p> <p>For blockchains that offer a DSL describing the smart contract interface, such as Ethereum's ABI (Application Binary Interface), FireFly offers a convenience tool to convert the DSL into the FFI format.</p> <p>NOTE: Contract interfaces are scoped to a namespace. Within a namespace each contract interface must have a unique name and version combination. The same name and version combination can exist in different namespaces simultaneously.</p> <ul> <li>HTTP API: Based on a Contract Interface, FireFly further defines an HTTP API for the smart contract, which is complete with an OpenAPI Specification and the Swagger UI. An HTTP API defines an <code>/invoke</code> root path to submit transactions, and a <code>/query</code> root path to send query requests to read the state back out.</li> </ul> <p>How the invoke vs. query requests get interpreted into the native blockchain requests are specific to the blockchain's connector. For instance, the Ethereum connector translates <code>/invoke</code> calls to <code>eth_sendTransaction</code> JSON-RPC requests, while <code>/query</code> calls are translated into <code>eth_call</code> JSON-RPC requests. One the other hand, the Fabric connector translates <code>/invoke</code> calls to the multiple requests required to submit a transaction to a Fabric channel (which first collects endorsements from peer nodes, and then sends the assembled transaction payload to an orderer, for details please refer to the Fabric documentation).</p> <ul> <li>Blockchain Event Listener: Regardless of a blockchain's specific design, transaction processing are always asynchronous. This means a transaction is submitted to the network, at which point the submitting client gets an acknowledgement that it has been accepted for further processing. The client then listens for notifications by the blockchain when the transaction gets committed to the blockchain's ledger.</li> </ul> <p>FireFly defines event listeners to allow the client application to specify the relevant blockchain events to keep track of. A client application can then receive the notifications from FireFly via an event subscription.</p> <ul> <li>Event Subscription: While an event listener tells FireFly to keep track of certain events emitted by the blockchain, an event subscription tells FireFly to relay those events to the client application. Each subscriptions represents a stream of events that can be delivered to a listening client with various modes of delivery with at-least-once delivery guarantee.</li> </ul> <p>This is exactly the same as listening for any other events from FireFly. For more details on how Subscriptions work in FireFly you can read the Getting Started guide to Listen for events.</p>"},{"location":"tutorials/custom_contracts/#custom-onchain-logic-async-programming-in-firefly","title":"Custom onchain logic async programming in FireFly","text":"<p>Like the rest of FireFly, custom onchain logic support are implemented with an asynchronous programming model.

The CLI can be used to create a docker-compose environment that runs the entirety of a FireFly network. This will include several different processes for each member of the network. This is very useful for people that want to build apps that use FireFly's API. It can also be useful if you want to make changes to FireFly itself, however we need to set up the stack slightly differently in that case.</p> <p>Essentially what we are going to do is have docker-compose run everything in the FireFly network except one FireFly core process. We'll run this FireFly core process on our host machine, and configure it to connect to the rest of the microservices running in docker-compose. This means we could launch FireFly from Visual Studio Code or some other IDE and use a debugger to see what's going on inside FireFly as it's running.</p> <p>We'll call this stack <code>dev</code>. We're also going to add <code>--external 1</code> to the end of our command to create the new stack:</p> <pre><code>ff init dev --external 1\n</code></pre> <p>This tells the CLI that we want to manage one of the FireFly core processes outside the docker-compose stack.

If you run FireFly from the <code>firefly</code> project directory you cloned from GitHub, it will automatically find these and apply them.

By default, most EVM clients do not store this reason in the transaction receipt. This is typically to reduce resource consumption such as memory usage in the client. It is usually possible to configure an EVM client to store the revert reason in the transaction receipt. For example Hyperledger Besu\u2122 provides the <code>--revert-reason-enabled</code> configuration option. If the transaction receipt does not contain the revert reason it is possible to request that an EVM client re-run the transaction and return a trace of all of the op-codes, including the final <code>REVERT</code> <code>REASON</code>.

In order to move from <code>Received</code> to <code>Tracking</code> several actions were performed: <code>AssignNonce</code>, <code>RetrieveGasPrice</code>, and <code>SubmitTransaction</code>.</p>"},{"location":"reference/blockchain_operation_status/#history-example","title":"History Example","text":"<pre><code>{\n    ...\n    \"lastSubmit\": \"2023-01-27T17:11:41.222375469Z\",\n    \"nonce\": \"14\",\n    \"history\": [\n        {\n            \"subStatus\": \"Received\",\n            \"time\": \"2023-01-27T17:11:41.122965803Z\",\n            \"actions\": [\n                {\n                    \"action\": \"AssignNonce\",\n                    \"count\": 1,\n                    \"lastInfo\": {\n   \u2003                    \"nonce\": \"14\"\n                    },\n                    \"lastOccurrence\": \"2023-01-27T17:11:41.122967219Z\",\n                    \"time\": \"2023-01-27T17:11:41.122967136Z\"\n                },\n   \u2003            {\n                    \"action\": \"RetrieveGasPrice\",\n                    \"count\": 1,\n                    \"lastInfo\": {\n                        \"gasPrice\": \"0\"\n                    },\n                    \"lastOccurrence\": \"2023-01-27T17:11:41.161213303Z\",\n                    \"time\": \"2023-01-27T17:11:41.161213094Z\"\n                },\n                {\n                    \"action\": \"SubmitTransaction\",\n                    \"count\": 1,\n   \u2003                \"lastInfo\": {\n                        \"txHash\": \"0x4c37de1cf320a1d5c949082bbec8ad5fe918e6621cec3948d609ec3f7deac243\"\n                    },\n   \u2003                \"lastOccurrence\": \"2023-01-27T17:11:41.222374636Z\",\n   \u2003                \"time\": \"2023-01-27T17:11:41.222374553Z\"\n   \u2003            }\n   \u2003        ],\n  \u2003     },\n \u2003      {\n \u2003\u2003         \"subStatus\": \"Tracking\",\n            \"time\": \"2023-01-27T17:11:41.222400219Z\",\n    \u2003       \"actions\": [\n   \u2003\u2003\u2003          {\n    \u2003\u2003\u2003\u2003            \"action\": \"ReceiveReceipt\",\n     \u2003\u2003\u2003\u2003           \"count\": 2,\n    \u2003\u2003\u2003\u2003            \"lastInfo\": {\n     \u2003\u2003\u2003\u2003\u2003              \"protocolId\": \"000001265122/000000\"\n    \u2003\u2003\u2003\u2003            },\n    \u2003\u2003\u2003\u2003            \"lastOccurrence\": \"2023-01-27T17:11:57.93120838Z\",\n    \u2003\u2003\u2003\u2003            \"time\": \"2023-01-27T17:11:47.930332625Z\"\n   \u2003\u2003\u2003          },\n   \u2003\u2003\u2003          {\n   \u2003\u2003\u2003\u2003             \"action\": \"Confirm\",\n    \u2003\u2003\u2003\u2003            \"count\": 1,\n    \u2003\u2003\u2003\u2003            \"lastOccurrence\": \"2023-01-27T17:12:02.660275549Z\",\n    \u2003\u2003\u2003\u2003            \"time\": \"2023-01-27T17:12:02.660275382Z\"\n    \u2003\u2003\u2003         }\n   \u2003\u2003       ],\n  \u2003     },\n  \u2003     {\n \u2003\u2003         \"subStatus\": \"Confirmed\",\n  \u2003\u2003        \"time\": \"2023-01-27T17:12:02.660309382Z\",\n  \u2003\u2003        \"actions\": [],\n  \u2003     }\n    ]\n    ...\n}\n</code></pre> <p>Because the <code>history</code> field is a FIFO structure describing the N most recent sub-status changes, some early sub-status changes or actions may be lost over time.

FireFly v1.0 allowed for the dynamic creation of new namespaces by broadcasting a namespace definition to all nodes. This functionality is _removed_ in v1.1.0. If your network relies on any namespaces that were created via a broadcast, you must add those namespaces to the `namespaces.predefined` list in your YAML config prior to upgrade. If you do not, they will cease to function after upgrading to v1.1.0 (all events on those namespaces will be ignored by your node).   <p>Identify queries for organization/node identities</p> Expand for migration details only if your application queries <code>/network/organizations</code> or <code>/network/nodes</code>.  Applications that query `/network/organizations` or `/network/nodes` will temporarily receive _empty result lists_ after upgrading to v1.1.0, just until all identities have been re-registered (see steps in \"After Upgrading\"). This is because organization and node identities were broadcast on a global \"ff_system\" namespace in v1.0, but are no longer global in v1.1.0.  The simplest solution is to shut down applications until the FireFly upgrade is complete on all nodes and all identities have been re-broadcast.  If this poses a problem and you require zero downtime from these APIs, you can proactively mitigate with the following steps in your application code:  - Applications that query the `/network/organizations` may be altered to _also_ query `/namespaces/ff_system/network/organizations` and combine the results (but should disregard the second query if it fails). - Applications that query the `/network/nodes` may be altered to _also_ query `/namespaces/ff_system/network/nodes` and combine the results (but should disregard the second query if it fails).  Further details on the changes to `/network` APIs are provided in the next section.   <p>Identify usage of changed APIs</p> Expand for migration details on all changes to <code>/namespaces</code>, <code>/status</code>, and <code>/network</code> APIs.  The primary API change in this version is that the \"global\" paths beginning with `/network` and `/status` have been relocated under the `/namespaces/{ns}` prefix, as this data is now specific to a namespace instead of being global. At the same time, the API server has been enhanced so that omitting a namespace from an API path will _query the default namespace_ instead. That is, querying `/messages` is now the same as querying `/namespaces/default/messages` (assuming your default namespace is named \"default\"). This has the effect that most of the moved APIs will continue to function without requiring changes. See below for details on the affected paths.  These global routes have been moved under `/namespaces/{ns}`. Continuing to use them without the namespace prefix **will still work**, and will simply query the default namespace.  <pre><code>/network/diddocs/{did}\n/network/nodes\n/network/nodes/{nameOrId}\n/network/nodes/self\n/network/organizations\n/network/organizations/{nameOrId}\n/network/organizations/self\n/status\n/status/batchmanager\n</code></pre>  These global routes have been moved under `/namespaces/{ns}` and have also been deprecated in favor of a new route name. Continuing to use them without the namespace prefix **will still work**, and will simply query the default namespace. However, it is recommended to switch to the new API spelling when possible.  <pre><code>/network/identities - replaced by existing /namespaces/{ns}/identities\n/network/identities/{did} - replaced by new /namespaces/{ns}/identities/{did}\n</code></pre>  These global routes have been have been permanently renamed. They are deemed less likely to be used by client applications, but any usage **will be broken** by this release and must be changed after upgrading.  <pre><code>/status/pins - moved to /namespaces/{ns}/pins (or /pins to query the default namespace)\n/status/websockets - moved to /websockets\n</code></pre>  The response bodies of the following APIs have also had fields removed. Any usage of the removed fields **will be broken** by this release and must be changed after upgrading.  <pre><code>/namespaces - removed all fields except \"name\", \"description\", \"created\"\n/namespaces/{ns} - same as above\n/namespaces/{ns}/status - removed \"defaults\"\n</code></pre> <p>Adjust or remove usage of admin APIs</p> Expand for migration details on all changes to <code>/admin</code> and <code>/spi</code>.  FireFly provides an administrative API in addition to the normal API. In v1.1.0, this has been renamed to SPI (Service Provider Interface). Consequently, all of the routes have moved from `/admin` to `/spi`, and the config section has been renamed from `admin` to `spi`. There is no automatic migration provided, so any usage of the old routes will need to be changed, and your config file will need to be adjusted if you wish to keep the SPI enabled (although it is perfectly fine to have both `admin` and `spi` sections if needed for migration).  The ability to set FireFly config via these routes has also been removed. Any usage of the `/admin/config` routes must be discontinued, and config should be set exclusively by editing the FireFly config file. The only route retained from this functionality was `/admin/config/reset`, which has been renamed to `/spi/reset` - this will continue to be available for performing a soft reset that reloads FireFly's config."},{"location":"releasenotes/1.1_migration_guide/#performing-the-upgrade","title":"Performing the Upgrade","text":"<p>Backup current data</p> <p>Before beginning the upgrade, it is recommended to take a full backup of your FireFly database(s).

In order to receive these events, we first need to instruct FireFly to listen for this specific type of blockchain event. To do this, we create an Event Listener. The <code>/contracts/listeners</code> endpoint is RESTful so there are <code>POST</code>, <code>GET</code>, and <code>DELETE</code> methods available on it. To create a new listener, we will make a <code>POST</code> request. We are going to tell FireFly to listen to events with name <code>\"Changed\"</code> from the FireFly Interface we defined earlier, referenced by its ID.

 <blockquote>
 <p><strong>NOTE</strong>: Contract interfaces are scoped to a namespace. Within a namespace each contract interface must have a unique name and version combination. The same name and version combination can exist in <em>different</em> namespaces simultaneously.</p>
 </blockquote>
-<ul>
-<li><strong>HTTP API</strong>: Based on a Contract Interface, FireFly further defines an HTTP API for the smart contract, which is complete with an OpenAPI Specification and the Swagger UI. An HTTP API defines an <code>/invoke</code> root path to submit transactions, and a <code>/query</code> root path to send query requests to read the state back out.</li>
-</ul>
-<p>How the invoke vs. query requests get interpreted into the native blockchain requests are specific to the blockchain's connector. For instance, the Ethereum connector translates <code>/invoke</code> calls to <code>eth_sendTransaction</code> JSON-RPC requests, while <code>/query</code> calls are translated into <code>eth_call</code> JSON-RPC requests. One the other hand, the Fabric connector translates <code>/invoke</code> calls to the multiple requests required to submit a transaction to a Fabric channel (which first collects endorsements from peer nodes, and then sends the assembled transaction payload to an orderer, for details please refer to the Fabric documentation).</p>
-<ul>
-<li><strong>Blockchain Event Listener</strong>: Regardless of a blockchain's specific design, transaction processing are always asynchronous. This means a transaction is submitted to the network, at which point the submitting client gets an acknowledgement that it has been accepted for further processing. The client then listens for notifications by the blockchain when the transaction gets committed to the blockchain's ledger.</li>

The client then listens for notifications by the blockchain when the transaction gets committed to the blockchain's ledger.</p>
 <p>FireFly defines event listeners to allow the client application to specify the relevant blockchain events to keep track of. A client application can then receive the notifications from FireFly via an event subscription.</p>
-<ul>
-<li><strong>Event Subscription</strong>: While an event listener tells FireFly to keep track of certain events emitted by the blockchain, an event subscription tells FireFly to relay those events to the client application. Each subscriptions represents a stream of events that can be delivered to a listening client with various modes of delivery with at-least-once delivery guarantee.</li>
