Binds methods to their class instance automagically
$ npm install autobindthis
const autobind = require('autobindthis');
class Bat {
constructor(name) {
this.name = name;
autobind(this);
}
ultrasonic() {
return `${this.name} comes closer!`;
}
}
const bat = new Bat('Quasel');
// Reference the method off the class instance
const ultrasonic = bat.ultrasonic;
// 'this' still refers to the class instance
ultrasonic();
//=> 'Quasel comes closer!'
// Without `autobind(this)`, the above would have resulted in
ultrasonic();
//=> Error: Cannot read property 'name' of undefinedBinds methods in self to their class instance.

Same as autobind, uses predefined set of method names to exclude the default React component methods.
class Robot extends React.Component {
constructor(props) {
super(props);
autobind.react(this);
}
// …
