Automatically binds methods defined within a component's Class to the current object's lexical `this` instance (similarly to the default behavior of React.createClass).
Automatically binds methods defined within a component's Class to the current object's lexical this
instance (similarly to the default behavior of React.createClass).
React 0.13 introduced the possibility to define components using plain JavaScript ES6 classes. But differently from the traditional React.createClass, user defined methods in a ES6 class are not automatically bound.
Autobind is an utility function that can be called from the class constructor to bind the class methods to the component instance.
To install the stable version:
npm install --save react-autobind
You will generally call autoBind from the class constructor, passing the 'this' context:
import autoBind from 'react-autobind';
constructor() {
super();
autoBind(this);
}
Autobind is smart enough to avoid binding React related methods (such as render and lifecycle hooks).
You can also explicitly specify which methods you want to bind:
import autoBind from 'react-autobind';
constructor() {
super();
autoBind(this, 'myMethod1', 'myMethod2');
}
import React from 'react';
import {render} from 'react-dom';
import autoBind from 'react-autobind';
class App extends React.Component {
constructor() {
super();
this.state = {
clickCounter: 0
}
autoBind(this);
}
componentDidMount() {
console.log("Component is mounted");
}
increment() {
this.setState({
clickCounter: this.state.clickCounter + 1
});
}
render(){
return (
<div>
<h1>Number of clicks: {this.state.clickCounter}</h1>
<button onClick={this.increment}>Increment Counter</button>
</div>
);
}
}
render(<App />, document.getElementById('root'));
