How to check for the existence of a module without an error being raised?

Question

In Angular 1.2, ngRoute is a separate module so you can use other community routers like ui.router instead.

I\'m writing an open-source mod

Answer 1

I would test for the service instead of the module itself.

// In controller
if($injector.has('$route')){

}
if($injector.has('$state')){

}

// In angular config
if($injector.has('$routeProvider')){

}
if($injector.has('$stateProvider')){

}
