Organizing requirejs and angularjs code structure into separate files

Looking to organize my Angular application with requirejs by separating controllers, services, and directives into different files. Hoping to achieve this structure:

src/
components/
    Navigation/
        index.js
        module.js
        NavigationController.js
        NavigationService.js

In module.js, aiming for something like this:

define(['angular', './NavigationService', './NavigationController'], function (angular, NavigationService, NavigationController) {
    'use strict';
    return angular.module('Myapp.Navigation', [])
        .controller('NavigationController', NavigationController)
        .service('NavigationService', NavigationService)
});

Wanting to define the controller/service in separate js files.

Struggling with file definitions. Attempted syntax like this:

//NavigationService.js
define( function() {

            this.doNavigation = function () {
                console.log('I am navigating');
            }
    });

But encountering issues. Any experience with this structure using requirejs?

Thank you!

Answer №1

Consider the following:

//NavigationService.js
define([], function() {
    NavigationHandler.$inject = ['$scope', '$http', 'myCustomService', 'etc'];
    function NavigationHandler($scope, $http, myCustomService, etc) {
        ...
    }
    return NavigationHandler;
});

You might find angular-require-lazy useful as well.

Answer №2

For a single application in Angular, you can skip using requirejs. The top level hierarchy in angular is the application itself, with its own set of modules. All necessary sources should be included from the start, eliminating the need for requirejs.

Instead, consider utilizing grunt with the concat plugin. This will consolidate all components of your application into a single file for easier loading.

If you do end up with a separate file for each application, then it may make sense to use requirejs for loading those files, but not individual modules.

Take a look at the angular code style guide for best practices on writing code.

UPDATE: If you have multiple common modules across applications, using require.js with angular.js could be beneficial. Check out this article on how to integrate the two: read and follow recommendations from this article. Otherwise, require.js may not be necessary.
