Automatically bind methods to their class instance
$ npm install --save auto-bind-es5
const autoBind = require('auto-bind-es5');
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();
//=> 'Rainbow is awesome!'
// Without `autoBind(this)`, the above would have resulted in
message();
//=> Error: Cannot read property 'name' of undefinedBind methods in self to their class instance. Returns the self object.
