autobindthis

Binds methods to their class instance automagically

Install

$ npm install autobindthis

Usage

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 undefined
