Synapse React Client

This project helps you integrate your app with the Synapse API backend.

See the available Components

Getting started with Synapse.

Synapse.org is a client written for the Synapse platform.

Installation

We provide multiple ways to add Synapse React Client to your project

NPM

Run the following command:
npm install synapse-react-client

Or add to your dependencies in package.json:
"synapse-react-client": "latest"

If using Typescript then you'll need to create a file called "synapse-react-client.d.ts" file with the following content: 

 declare module "synapse-react-client"

Installation without npm or yarn

Usage

See index.ts for a comprehensive list of components that can be used.

To function properly, all components must be wrapped in a SynapseContextProvider. To make authenticated requests, you must provide the user's access token as a property to the context provider, among other values. You may maintain this in state, or provide it however you like.

The context provider also maintains a shared cache (via react-query). It is recommended to place the provider at the highest possible point in your component tree, and to use the same provider across components if possible.

Example:

const myToken = "example-token" // this value may also be undefined, if a user is not signed in
const useUtcTime = true
const inExperimentalMode = false

<SynapseContextProvider synapseContext={{ accessToken: myToken, isInExperimentalMode: inExperimentalMode, utcTime: useUtcTime }} >
  <EntityFinder {...entityFinderProps} />
</SynapseContextProvider>

Setting Endpoints

Configuring endpoint destinations for repo and portal

Specifying the following in the window object will override request endpoints:

window.SRC.OVERRIDE_ENDPOINT_CONFIG = {
  PORTAL: '<endpoint>',
  REPO: '<endpoint>',
}

Note - this will apply to all calls being made.

Theming

Style

Synapse React Client uses Dart Sass. The core css lives in src/lib/style and src/lib/template_style.

  • src/lib/style contains all scss that doesn't use any external variables.
  • src/lib/template_style contains any scss files that require external variables.

Overrides

For a list of variables you can override, see src/lib/style/abstracts/_variables.scss.

Override the variables by importing the SCSS in your project like so:

@use 'node_modules/synapse-react-client/dist/style/main.scss' with (
  $primary-action-color: $-my-primary-color, 
  $secondary-action-color: $-my-secondary-color,
  // ...any other overrides continue
);
@use 'node_modules/synapse-react-client/dist/template_style/Index.scss';

In this example, make sure that the node_modules folder is in your load path.

Configuration Files

File Description
./types.d.ts In general this would be used as a library with type declarations for other client developers using Typescript. Currently, it contains only definitions for global CDNs used in the project.
./tsconfig.json Typescript configuration for IDEs, especially VSCode.
./tsconfig.build.json Typescript configuration for the emitted build
./rollup.config.js Rollup configuration to create the minified package

Project Development

This project's core dependencies are Typescript, and rollup.

Motivation for dependencies-

  • Typescript is a superset of Javascript that provides static typing. This catches many bugs at compile time and makes the client much more self-documenting.

  • rollup allows the client to be built as a UMD bundle without having to eject the application from react's built in webpack configuation. The primary motivation for bundling the package as a UMD build is using the package in synapse.org.

Caveats of these dependencies- When rollup bundles the app and resolves an import module from 'library' statement it will attempt to include the module in the final output. This is done by looking through the node_modules/ folder and attempting to copy the code for the library, it's done via rollup-plugin-node-resolve. This doesn't work for every library nor should it be done for every library. React, if bundled in this fashion would bloat the bundle to 100k plus lines, its prefereable to include React via CDN. Additionally, some bundles don't resolve well (e.g. they have circular dependencies). If this happens you have to use a CDN for the code and tell rollup to recognize the import as a global in the final output file. In the rollup config, specify this in the external and output.globals fields.

Release Cycle

The develop branch points to the development version of Synapse React Client. Feature branches should be created from and pulled into develop.

The main branch contains the current release version of Synapse React Client.

To release a new version on NPM, bump the version number in package.json in develop, and merge the changes from develop to master. We have GitHub actions configured to automatically build and publish the new version.

All proposed changes (to be merged into develop or master) must be via a Pull Request with a code review

Hotfixes

If an issue in master is detected a hotfix branch is created from master Once the hotfix is complete it is merged to both develop and master

Adding a new component and Publishing a new version of SRC

To expose a component from the library you must export it from index.ts.

To expose a component for use in synapse.org, you must export it from rollup.index.ts. See Project Development for more information on rollup and synapse.org.

To release the react-client, bump the package version, merge into main, and run yarn publish. Note - you must have access to the synapse-react-client npm package to be able to run the command. Publising the package will also release a new version of the rollup build, it can be pulled down using unpkg.com, the URL is available here

Updating this Project to New Releases

  • react-scripts is a development dependency in this project.

To update to a new version of react-scripts, open the changelog, find the version you’re currently on (check package.json in this folder if you’re not sure), and apply the migration instructions for the newer versions.

In most cases bumping the react-scripts version in package.json and running npm install in this folder should be enough, but it’s good to consult the changelog for potential breaking changes.

We commit to keeping the breaking changes minimal so you can upgrade react-scripts painlessly.

Available Scripts

Before doing anything else run:

yarn (or yarn install)

In the project directory, you can run:

yarn start

Runs the Synapse React Client Styleguidist browser. In your browser, navigate to http://127.0.0.1:6060 to view it.

It will automatically open localhost, but you need to use 127.0.0.1 for CORS preflight OPTIONS request to work properly.

The page will reload if you make edits.
You will also see any lint errors in the console.

yarn test

Launches the test runner in the interactive watch mode.

yarn test:coverage

Launches the test runner in the non-interactive mode to run all tests and calculate test coverage.

The client has its configuration file for tests in src/setupTests.js.

  • Any predefined functionality must be defined there and CDN dependencies must be imported as npm modules.

Links to Resources on Testing:

yarn deploy

Build and deploy our style guide documentation to "upstream"
Available at https://sage-bionetworks.github.io/Synapse-React-Client/

yarn start-docs

Starts a style guide dev server, available at http://localhost:6060/

Common issues with failed tests -

React state isn't being updated.

Wrap your code that updates the component inside https://testing-library.com/docs/preact-testing-library/api#act

Enzyme isn't finding the component

If using a class component:

  1. Try using https://enzymejs.github.io/enzyme/docs/api/ReactWrapper/mount.html - this recursively renders all child components.
  2. Try using https://enzymejs.github.io/enzyme/docs/api/ReactWrapper/update.html - this will sync the enzyme component tree snapshot with the react component tree, useful to use after running a stateful action on a component.

Debugging the tests

There are open issues in the microsoft vscode repository that block the ability to run debug mode on our tests.

  1. Update launch.json with the json snippet below.
  2. The command will fail because of the way vscode treats quotations inside launch.json, re-run the failed command by replacing the text node_modules/(?!(lodash-es|jest\*)/) with "node_modules\/(?!(lodash-es|jest\*)/\)" and append the command set -H+ to the front e.g. set -H+ && command with modified text "node_modules\/(?!(lodash-es|jest\*)/\)"

}

yarn run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

It produces a build for npm distribution and umd.

To test umd build, start a web server in the /src directory and visit the SingleFileBuild demo page index.html. For example, http://localhost:8000/demo/SingleFileBuild/

yarn run build:rollup

This project can be built as a umd bundle. It produces two files synapse-react-client.production.min.js and synapse-react-client.production.min.styles.css. Note - this script is run automatically as part of the build command.

npm run eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.

Supported Language Features and Polyfills

This project supports a superset of the latest JavaScript standard.
In addition to ES6 syntax features, it also supports:

Learn more about different proposal stages.

While we recommend to use experimental proposals with some caution, Facebook heavily uses these features in the product code, so we intend to provide codemods if any of these proposals change in the future.

Note that the project only includes a few ES6 polyfills:

If you use any other ES6+ features that need runtime support (such as Array.from() or Symbol), make sure you are including the appropriate polyfills manually, or that the browsers you are targeting already support them.

Syntax Highlighting in the Editor

To configure the syntax highlighting in your favorite text editor, head to the relevant Babel documentation page and follow the instructions. Some of the most popular editors are covered.

Displaying Lint Output in the Editor

Note: this feature is available with [email protected] and higher.

Some editors, including Sublime Text, Atom, and Visual Studio Code, provide plugins for ESLint.

They are not required for linting. You should see the linter output right in your terminal as well as the browser console. However, if you prefer the lint results to appear right in your editor, there are some extra steps you can do.

You would need to install an ESLint plugin for your editor first.

A note for Atom linter-eslint users

If you are using the Atom linter-eslint plugin, make sure that Use global ESLint installation option is checked:

For Visual Studio Code users

VS Code ESLint plugin automatically detects Create React App's configuration file. So you do not need to create eslintrc.json at the root directory, except when you want to add your own rules. In that case, you should include CRA's config by adding this line:

{
 // ...
 "extends": "react-app"
}

Then add this block to the package.json file of your project:

{
 // ...
 "eslintConfig": {
   "extends": "react-app"
 }
}

Finally, you will need to install some packages globally:

npm install -g [email protected] [email protected] [email protected] [email protected] [email protected] [email protected] [email protected]

We recognize that this is suboptimal, but it is currently required due to the way we hide the ESLint dependency. The ESLint team is already working on a solution to this so this may become unnecessary in a couple of months.

Debugging in the Editor

This feature is currently only supported by Visual Studio Code editor.

Visual Studio Code supports live-editing and debugging out of the box with Create React App. This enables you as a developer to write and debug your React code without leaving the editor, and most importantly it enables you to have a continuous development workflow, where context switching is minimal, as you don’t have to switch between tools.

You would need to have the latest version of VS Code and VS Code Chrome Debugger Extension installed.

Then add the block below to your launch.json file and put it inside the .vscode folder in your app’s root directory.

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Chrome",
      "type": "chrome",
      "request": "launch",
      "url": "http://localhost:3000",
      "webRoot": "${workspaceRoot}/src",
      "userDataDir": "${workspaceRoot}/.vscode/chrome",
      "sourceMapPathOverrides": {
        "webpack:///src/*": "${webRoot}/*"
      }
    }
  ]
}

Start your app by running npm start, and start debugging in VS Code by pressing F5 or by clicking the green debug icon. You can now write code, set breakpoints, make changes to the code, and debug your newly modified code—all from your editor.

jsconfig.json

For improved vscode intellisense support you can optionally add a jsconfig.json to the root (it should lie at the level of dist/ node_modules/ public/) of the project directory. It tells vscode more about the projects settings such as where to look for relative imports (specified with the baseUrl) and the js version being used. View the full docs here.

{
  "compilerOptions": {
    "baseUrl": "./src",
    "jsx": "react",
    "module": "es6"
  }
}

rollup.config.js

This is required to build a umd build, docs can be found here: https://rollupjs.org/guide/en
