react-class

react-class

A carefully crafted base class for all your React components

Features

• auto-bind methods
• optimized to only auto-bind non-lifecycle methods

Install

$ npm install react-class --save

Usage

Instead of extending React.Component you have to extend the class exported by react-class.

import Component from 'react-class'
// or import { Component } from 'react-class

class MyApp extends Component {
  render() {
    return <div {...props} onClick={this.onClick}>
      //onClick is auto-bound to "this", so you can keep your code dry
    </div>
  }

  onClick(){
    console.log(this)
    // this is correctly bound to the component instance
  }
}

Just auto-binding

If you don't want to extend the class exported by react-class and instead just want autobinding, you can just import the autoBind function directly.

import 'react-class/autoBind'

// or

import { autoBind } from 'react-class'

// or

var autoBind = require('react-class/autoBind')

After importing/require-ing it, call autoBind in the component constructor:

import autoBind from 'react-class/autoBind'

class MyApp extends React.Component {
  constructor(props) {
    super(props)

    autoBind(this)
  }

  render() {
    // ... your rendering logic
  }
}

FAQ

What problems does it solve?

Autobinding, which is a nice-to-have feature!

What if I want to remove it in the future?

react-class is a very thin layer around React.Component, so just in case you decide removing it in the future, you'll be safe and will only have to do very minor code changes.

We're not doing anything magical!
