Useful Dicts

A small collection of Dicts for Meteor. Store some validated data and retrieve it easily.

Dict

const dict = new Dict();
const dictTwo = new Dict({value: true});

You can construct a new dict with or without an object of key/value pairs.

dict.get('value');

Will return the value set. If it is not found it will throw an Error.

dict.set({valueTwo: true, valueThree: true});

You can set more than one key/value pair at once.

const dictTwo = new Dict({}, {throwingGet: false});

You can disable Error throws at .get method.

Validated Dicts

This package will give you a group of validated dicts you can use to store data of the same type. All these classes inherit from Dict, so you'll just use .get and .set methods as above.

// a dict that will accept only String type values
const stringsDict = new StringsDict();

// a dict that will accept only Number type values
const numbersDict = new NumbersDict();

// a dict that will accept only Boolean type values
const booleansDict = new BooleansDict();

// a dict that will accept only Function type values
const functionsDict = new FunctionsDict();

Errors are thrown if you try to .set values of the wrong type in them.

Special Dicts

These are dicts with extended functionality.

Hooks Dict

It allow to execute in sequence a group on functions on some data, and return that data, eventually changed by the fuctions above.

const hooksDict = new HooksDict();
// add a function to an automatically created group of functions
hooksDict.add('example.functions', function doSomething(data) {
	// remember to always return something or an error will be thrown
	return data;
});
// later on anywhere in your application
hooksDict.add('example.functions', function doSomethingElse(data) {
	// do something else
	return data;
});

Note that the functions added will always be called with only one argument.

// execute the group of functions you have just created
const result = hooksDict.run('example.functions', data);
// if you call run on a group of hooks that does not exist or is empty,
// it will return the same data you passed to it.
const resultTwo = hooksDict.run('example.noHooks', data);
// => data is returned as result

You must pass only one data argument, other arguments will be ignored.
