javascript - Access constant directly from Angular module - Stack Overflow

I have the following lines:

var app = angular.module('app', []);
app.constant("const", {
   foo: "bar",
   test: "123"
});

I would like to now access the information in constant directly from the module app. Something like this didn't work:

console.log(app.constant.const.foo);

I know you can inject constants into controllers, services etc and access the information but for my purposes, I would like to access them straight off the module.

Is the only way to access a registered constant is to inject it into a controller/service/etc?

• 1 It seems that this is the only way (to inject), yes – Mik378 Commented Aug 11, 2014 at 0:38

Assuming, somehow, you want an access to the const outside the angularjs environment.

Then you have to retrieve it from an injector, and there are two ways you can get the injector:

1. Get the current injector of a running angularjs application like this:

   var injector = angular.element(document).injector(); // assuming `ng-app` is on the document
   injector.get('const');
   

2. Create a new injector from existing modules:

   var injector = angular.injector(['ng', 'app']); // note the 'ng' module is required this way
   injector.get('const');

Hope this helps.

If you really want to access the constant directly, you could do:

var app = angular.module('app', []);
var app.constants = {foo: "bar", test: "123"};
app.constant("const", app.constants);
console.log(app.constants.foo);

But, I don't see a real benefit ;)
