Determine if module is already loaded?

[rmunch]

I'm curious if there's a way to check if a module has already been loaded? I see there's a private function moduleExists() that does this, but it's not accessible from outside the module. Maybe a new method could be exposed to support this, e.g. $ocLazyLoad.isLoaded('my.module')?

My use case is that I need to recompile a directive template after lazy-loading a module containing some UI components. I'd like to set it up so it only does this if the module has not yet loaded.

Thanks!

Well there is an undocumented function named getModules that returns an array with the list of the loaded modules, you could use it with indexOf:

if($ocLazyLoad.getModules().indexOf('my.module') > -1) {
  // ...
}

Otherwhise you can use the same thing that I do in my lib:

var isLoaded = false;
try {
        isLoaded = angular.module(moduleName);
    } catch(e) {
        if(/No module/.test(e) || (e.message.indexOf('$injector:nomod') > -1)) {
            isLoaded = false;
        }
    }

But if you want I could add a isLoaded function, yes.

+1 for making it available outside.

I was looking for the same thing last week and come across several try/catch based solutions. Your internal method with additional regex inside was the prettiest to be fair.

If it can be useful, I don't see why not.
I'll do it when I have the time. If you want to have it faster, you can do a PR :)

Available in master. I'll make a new release soon.
