Automatically bind methods to their class instance
npm install auto-bind> Automatically bind methods to their class instance
It also correctly binds inherited properties.
``sh`
npm install auto-bind
`js
import autoBind from '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();
//=> 'Rainbow is awesome!'
// Without autoBind(this), the above would have resulted in`
message();
//=> Error: Cannot read property 'name' of undefined
