Tips on optimizing Angular dependency injection for concatenation and minification?

For better organization and ease of editing, I've structured my Angular application into separate files. Here's a snippet from my app.js where I define the dependencies:

app.js

var app = angular.module('app', ['ngResource', 'ngRoute', 'app.services', 'app.controllers', 'app.feed','app.directives', 'app.factories']);

app.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
    ...
}]);

This is how I've set up the dependencies in one of the files:

services.js

var app = angular.module('app.services', []);

app.factory('AuthService', ['$scope'], function($scope) {
    ...
}]);

My issue arises when concatenating the scripts as it constantly redefines the 'app' variable. While considering removing the 'var' declaration to solve this problem, I prefer keeping my files separated.

Is there a way to maintain the integrity of dependency injections in my app.js while preserving the segregation of files?

Answer №1

To avoid repeatedly declaring the app variable, you can utilize the module pattern outlined in the Angular Style Guide:Modules. Instead of explicitly stating app for every dependency:

var app = angular.module('app.services', []);

app.factory('AuthService', ['$scope'], function($scope) {
    ...
}]);

You can associate your service, component, directive, controller, etc with the appropriate module like so:

angular.module('app.services')
.factory('AuthService', ['$scope'], function($scope) {
    ...
}]);

The declaration of an 'app.services' module only needs to be done once.

Refer to the Angular Style Guide:Modules for more detailed explanations.
