Angular.js - re-open and add dependencies to an already bootstrapped
application
Is there a way to inject a late dependency to an already bootstrapped
angular module? Here's what I mean:
Say that I have a site-wide angular app, defined as:
// in app.js
var App = angular.module("App", []);
App.directive("fancy-table", ...)
And in every page:
<html ng-app="App">
Later on, I'm reopening the app to add logic based on the needs of the
current page:
// in reports.js
var App = angular.module("App")
App.controller("ReportsController", ['$scope', function($scope) {
// .. reports controller code
}])
Now, say that one of those on-demand bits of logic also requires their own
dependencies (like ngTouch, ngAnimate, ngResource, etc). How can I attach
them to the base App? This doesn't seem to work:
// in reports.js
var App = angular.module("App", ['ui.event', 'ngResource']); // <-- raise
error when App was already bootstrapped
I realize I can do everything in advance, i.e -
// in app.js
var App = angular.module("App", ['ui.event', 'ngResource', 'ngAnimate',
...]);
Or define every module on its own and then inject everything into the main
app (see here for more):
// in reports.js
angular.module("Reports", ['ui.event', 'ngResource'])
.controller("ReportsController", ['$scope', function($scope) {
// .. reports controller code
}])
// in home.js
angular.module("Home", ['ngAnimate'])
.controller("HomeController", ['$scope', '$http', function($scope, $http){
// ...
}])
// in app.js, loaded last into the page (different for every page that
varies in dependencies)
var App = angular.module("App", ['Reports', 'Home'])
But this will require I initialize the App everytime with the current
page's dependencies.
I prefer to include the basic app.js in every page and simply introduce
the required extensions to each page (reports.js, home.js, etc), without
having to revise the bootstrapping logic everytime I add or remove
something.
Is there a way to introduce dependencies when the App is already
bootstrapped? What is considered the idiomatic way (or ways) to do this?
I'm leaning towards the latter solution, but wanted to see if the way I
described could also be done. thanks.
