What does this library offer?

• Minimal: It is a tiny yet crucial library for creating React apps in a much more faster and safer way.
• Pure Abstraction: It is so abstract that it doesn't even depend on react module. That means you can use it in any script too.
• Fully Documented: The project is well documented and has comprehensive unit tests.

How to install? 📦

Since the package is in npm you can use the command below to add it to your project packages:

npm i react-event-dispatcher

How to use? 🚀

In your React file you have to import it in ES6 syntax:

import EventEmitter from 'react-event-dispatcher'

Now you have full access to the library. Cheers! Let's try it with a basic example:

const eventToDispatch = () => console.log('It really works 👌')
EventDispatcher.dispatch('RandomComponent', eventToDispatch)
EventDispatcher.runOne('RandomComponent')
// You should see 'It really works 👌' on your console.

A Complete Example

// Written in Node
const EventDispatcherFactory = require('react-event-dispatcher')
const myDispatcher = EventDispatcherFactory.create('MyDispatcher')

class ParentComponent {
	constructor() {
		this.updateChildName = myDispatcher.getOne('$child')
	}
}

class ChildComponent {
	// Assume that this._name is private
	constructor() {
		this._name = '@ChildComponent'
		// In React you don't need to bind
		// Just create a method in Component with arrow 
		// function since it is already bound to this
		const updateName = function(name) {
			this._name = name
		}.bind(this)
		EventDispatcherFactory.use('MyDispatcher').dispatch('$child', updateName)
	}

	get name() {
		return this._name
	}
}

const childComponent = new ChildComponent()
const parentComponent = new ParentComponent()
parentComponent.updateChildName('@AwesomeComponent')
console.log({
	name: childComponent.name
})

# output
{ name: '@AwesomeComponent' }

Motivation and Architecture

Motivation

I have been working on React quite lately. And one of the problems I had encountered a lot is event propagation between miscellaneous components. At some point it had been so cumbersome that I had to left some of the projects that I have been dedicated for. So I wrote this minimal yet efficient library for React.

Architecture

Since version 1.8.0, the main architecture has been changed drastically. The architecture schema is like below:
