hof-behaviour-hooks

HOF Behaviour enabling lifecycle hooks for extending functionality in main form pipeline.

Usage

With mixwith.js

const mix = require('mixwith').mix;
const Hooks = require('hof-behaviour-hooks');
const BaseController = require('hof-form-controller');
 
class MyController extends mix(BaseController).with(Hooks) {
  ...
}

MyController now extends hof-form-controller and has hof-behaviour-hooks functionality mixed in.
