React Easy State

Easy State aims to make React's state management simpler without adding new syntax. To achieve this it makes the following modifications.

• It replaces React's setState() with plain native JavaScript.
• It bypasses the asynchronity and performance issues of setState.
• It auto binds your component's methods.

Installation

npm i react-easy-state --save

Usage

import React, { Component } from 'react'
import easyState from 'react-easy-state'

@easyState
export default class App extends Component {
  render() {
    const { name } = this.state

    return (
      <div>
        <div>Name: <input onChange={this.updateName}/></div>
        <p>Hello {name}!</p>
      </div>
    )
  }

  updateName (ev) {
    this.state.name = ev.target.value
  }
}

About decorators

@easyState is a decorator, which is not yet part of the JS language. You can learn how to enable decorators with babel here or you can use the older export default easyState(Comp) syntax.

How does it work?

Under the hood it uses the @nx-js/observer-util library, which relies on ES6 proxies to observe state changes. Thanks to the Proxies it doesn't have edge cases or limitations. You can write any JS code without worrying about the render function. This blog post gives a little sneak peek under the hood of the observer-util.

The NX Framework

This library is the side effect of a front-end framework I have been working on in the past year. Please take a look at the NX Framework if you have some time. Have a nice day!
