Backbone's plugin design

backbone-plugin.js

'use strict';

// Dependencies
var {Model} = require('backbone');


module.exports = class PluginAdapter extends Model {

  constructor(parent, options) {
    this.name = options.name;
    super(this.parse(parent));
    parent.use('save:before', this.save.bind(this));
    parent.on('change:'+this.name, parent => this.set(this.parse(parent)));
  }

  // logic to parse plugin data from parent model
  parse(parent) {
    return parent.get(this.name);
  }
  
  // dump data
  dump() {
    return this.toJSON()
  }

  // on save parent
  save(parent) {
    parent.set(this.name + '_attributes', this.dump());
    parent.unset(this.name, { silent: true });
  }
