• Just one file for each type of object.
• Each file contains all objects of that type.
• Not real applications (tutorials, demos, hello-worlds).
• Not recommended at all.

Directory layout

• Files of the same object type are organized into a single folder.
• Hard to find a file if there are more than 10 in a sub-folder.
• Related files of a module are separated from each other.

Directory layout

• Files of the same function are together.
• Easy to find related files.
• Unit test files (specs) side-by-side with your client code, it is easier to keep them up to date since they are in sight, easy to TDD.
• You could even go more specific if the app is larger, split files into sub-folders by types.
• Recommended to medium and large apps. 

Organized by feature

Modules

• Reusable software components.
• Gives simplicity to our application.

A module should be...

• Ability to use them in other applications.
• Encapsulations of your code. exposing an API.

Specialized

• Should have a very specific function.
• Should solve the single problem that it's meant to solve.
• Exposed API should be clean.

Independent

• Should know the less possible of the other modules.
• Communicate with others using events.

Decomposable

• Simple to test individually.
• Isolation from the other modules.
• Other components should work without it.

Recomposable

• Should fit with other modules in different ways.
• Able to use in different version of the app

Substitutable 

• Should be possible to substitute a module with others as long as it exposes the same interface.

Organizing modules

Module recomendation

App

Module1

Module2

Module3

Main module might not have actual objects in it, just a collection of sub-modules.

Sub-modules you want to add to the main module application

Name collisions

• AngularJs modules do not provide any sort of namespacing that would prevent name collisions.
• If the injector finds objects with the same name, one will override the other.
• When collisions happen they are silent, no error is thrown, Angular injector takes the last one that was injected.

Avoiding name collisions

Name objects uniquely for each module. 

Use a simple camel-case prefix of two or three digits to represent the module.

Naming Objects

Controllers

- Costumers

- CostumersCtrl

- CostumersController

- costumers.controller

As long as the objects names are consistent trough the project, we are ok .

Services

- Costumers

- CostumersSvc

- CostumersService

- costumers.service

Directives*

- myAvatar

- myAvatarDrct

- my-avatar

Partial Views

- customersView.html

- customers.html

Loads asynchronously modules at runtime. 

Asynchronous Module Definition (AMD)

define(['amd1', 'amd2'],
  function myModule(amd1, amd2) {
    var testResults = {
        test1: amd1.test(),
        test2: amd2.test()
      },

      // Define a public API for your module:
      api = {
        testResults: function () {
          return testResults;
        }
      };

    return api;
  });

RequireJs

Creates a bundle file

Universal Module Definition (UMD)

//bar.js
module.exports = function (n) { 
    return n * 3 
};

//foo.js
var bar = require('./bar');

module.exports = function (n) {
    return n * bar(n);
};
