#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.

• _validate - 'pre-validate', 'post-validate'

  'field-1': {
    hooks: {
      'post-locals': (req, res, next) => {
        Object.assign(res.locals, {
          foo: 'bar'
        });
        next();
