This repository contains the example code of a working Request Interceptor in AngularJS 1.5 which automatically displays a loading modal when a http request is made.

You will need the content of request-interceptor.service.js and your AngularJS 1.5 app wil need to consume as such:

angular.module('app', [])
.config(HttpProvider)

Within the interceptor you can see the line $('#loadingModal').modal('show') this is how we display and hide the loading modal to block user's interaction. This is entirely up to you in how you would like to having a loading blocker but I have opted for Bootstrap's Modal Component, which you find in loading-blocker.html.

Finally you need the content of helper.config.js which contains the helper function to add your desired url to be blocking and to check which request should be blocking.

Once you have registered the Request Interceptor as shown above, you can start using this feature.

1. Inject $rootScope into your controller
2. Add your full or base url via the method addUrlToWait

That's it, once the http service intercepts a url similar to the one you've added it will display the loading modal.
