Using a known set of compatible dependency versions, Orchestra takes the pain away from setting up your Marionette applications. Just install and go!

Utilising the power of the Marionette framework along with a proven architecture for messaging in Backbone.Radio you have the structure and core tools needed to implement large Javascript applications that are designed to support multi-currency and multi-languages from the outset.

Install

To install Orchestra with node package manager use:

npm install --save orchestra

Getting started

Orchestra works best using ES6 imports, we recommend using Babel.js to import the library. If you wish to use a different module loader take a look at the examples below:

ES6

import Orchestra from 'orchestra';

Browserify

var Orchestra = require('orchestra');

NOTE: we recommend the use of browserify-shim property to point to the commonjs version of Orchestra located in the lib folder.

Requirejs

require.config({
    baseUrl: "/path/to/scripts",
    paths: {
        "Orchestra": "./node_modules/orchestra/lib/index"
    }
});

Included Libraries

Orchestra exports a number of useful libraries used when building large scale Javascript applications, for details on the usage of these libraries please use the links below:

Backbone.js

repo | docs

"Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface."

To access Backbone properties via Orchestra, simply replace Backbone. with Orchestra.

var Orchestra = require('orchestra');
var collection = new Orchestra.Collection();

Marionette.js

repo | docs

"Marionette simplifies your Backbone application code with robust views and architecture solutions."

To use Marionette functionality just replace Marionette. with Orchestra.

var Orchestra = require('orchestra');
var CollectionView =  Orchestra.CollectionView.extend({});

Lodash

repo | docs

"A JavaScript utility library delivering consistency, modularity, performance, & extras."

To access the Lodash API from Orchesra, just use the Orchestra._ property.

var Orchestra = require('orchestra');
var _ = Orchestra._;

_.each(someArray, function(item, index) {
  console.log('item at ' + index + ' = ' + item);
});

Backbone.Radio

repo

"Backbone.Radio provides additional messaging patterns for Backbone applications."

To access Radio's API via Orchestra just use the Orchestra.Radio property.

var Orchestra = require('orchestra');
var soundChannel = Orchestra.Radio.channel('sound');

Backbone.Routing

repo

"Simple router and route classes for Backbone."

Backbone.Routing exposes 2 classes: Router and Route. These class are available via Orchestra using the following syntax:

var Orchestra = require('orchestra');

var IndexRoute = Orchestra.Route.extend({
  initialize(options) {
    this.foo = options.foo;
  },

  fetch: function() {
    // fetch model/collection
  },

  render: function() {
    // render a view, called after `fetch`
  },

  destroy: function() {
    // clean up view
  }
});

var Router = Orchestra.Router.extend({
  initialize: function(options) {
    // do stuff on init
    this.foo = options.foo;
  },

  onBeforeEnter: function() {
    // do something before entering any of the routes, e.g. check authentication, highlight navbar
  },

  routes: {
    '': 'index'
  },

  index: function() {
    return new IndexRoute({
      foo: this.foo
    });
  }
});

Backbone.Service

repo

"Simple service class for Backbone."

Backbone.Service extends Backbone.Radio's channel functionality by taking in a requests hash and returning a Promise from each one. The start and stop methods make Backbone.Service a great way to break up applications into modular components. To use Services in Orchestra, follow this API:

var Orchestra = require('orchestra');

var AuthService = Orchestra.Service.extend({
  start: function() {
    this.user = new User();
    return this.user.fetch();
  },

  requests: {
    isAuthenticated: 'isAuthenticated',
    authenticate: 'authenticate'
  },

  isAuthenticated: function() {
    return this.user.get('isAuthenticated');
  },

  authenticate: function() {
    this.user.authenticate();
  },

  onError: function(err) {
    console.log('Err!', err);
  }
});

var authService = new AuthService();

var Router = Orchestra.Router.extend({
  onBeforeEnter: function() {
    // check authentication
    authService.request('isAuthenticated').then(isAuthenticated => {
      if (!isAuthenticated) {
        this.cancel();
        history.navigate('login', { trigger: true });
        return;
      }
    }).catch(err => {
      if (!isAuthenticated) {
        this.cancel();
        history.navigate('login', { trigger: true });
        return;
      }
    });
  },

  routes: {
    '': 'index'
  },

  index: function() {
    return new IndexRoute();
  }
});

Backbone.Storage

repo

"A simple storage class for Backbone Models and Collections."

Backbone Storage combines Backbone Models and Collections into a single, easy to use API. To access the Storage class in Orchestra, use the following API:

var Orchestra = require('orchestra');
var Book = require('./model)';
var Books = require('./collection');

var BookStore = Orchestra.Storage.extend({
  model: Book,
  collection: Books
});

var bookStore = new BookStore();

// get a single book
bookStore.find(1).then(model => {
  model.get('name'); // >> A Tale of Two Cities
});

// get all books
bookStore.findAll().then(collection => {
  collection.length; // >> 10
});

// save a book to the server
var book = new Book({ name: 'Lolita' });
bookStore.save(book).then(model => {
  model.id; // >> 11
});

Backbone.Cocktail

repo

"Break out your shared Backbone.js model/collection/view behaviors into separate modules and mix them into your classes with Cocktail - an implementation of Backbone mixins."

To add mixins to your Backbone classes with Orchestra, follow this API:

var Orchestra = require('orchestra');
var CollectionView =  Orchestra.CollectionView.extend({});

Orchestra.mixin(CollectionView, MyMixins.SelectMixin, MyMixins.SomeOtherMixin);

Backbone.Syphon

repo

"Backbone.Syphon aims to make it easy to serialize the fields of a Backbone.View into a simple JSON object that contains all of the values."

To easily serialize forms fields into a JSON representation with Orchestra, follow this API:

Orchestra.LayoutView.extend({
  events: {
    "submit form": "formSubmitted"
  },
  formSubmitted: function(e){
    e.preventDefault();
    var data = Backbone.Syphon.serialize(this);
  },
});

Backbone.Validation

repo

"A validation plugin for Backbone.js that validates both your model as well as form input."

To validate forms and inputs with Orchestra, follow this API:

// Define validation schema in model
var User = Orchestra.Model.extend({
  validation: {
    email: {
      required: true,
      pattern: 'email',
    },
    age: {
      range: [1, 80]
    },
  }
});

// Bind validation to view
var View = Orchestra.LayoutView.extend({
  initialize: function(){
    this.model = new User();
    Orchestra.Validation.bind(this);
  },
  events: {
    "submit form": "formSubmitted"
  },
  formSubmitted: function(e){
    this.model.preValidate({
      email: '[email protected]',
      age: 55,
    });
  },
});

jQuery

repo | docs

"jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers."

To access the $ property via Orchestra look at the following example:

var Orchestra = require('orchestra');
var $ = Orchestra.$;

$('#someSelector').append('<p>hi!</p>');

Handlebars

repo | docs

"Handlebars provides the power necessary to let you build semantic templates effectively with no frustration."

Orchestra recommends the use of Handlebars as a templating language for your view layer. The framework provides some useful helpers to allow you to manage multi-currency and multi-language applications.

Built-in Helpers

• Currency
• Translation
• Local Storage
• Visibility
