auto-bind

Automatically bind methods to their class instance

Install

$ npm install --save auto-bind

Usage

const autoBind = require('auto-bind');

class Unicorn {
	constructor(name) {
		this.name = name;
		autoBind(this);
	}
	message() {
		return `${this.name} is awesome!`;
	}
}

const unicorn = new Unicorn('Rainbow');

// Grab the method off the class instance
const message = unicorn.message;

// Still bound to the class instance
message();
