This example will help you to learn how to interact between your backened RESTful apps and AngularJS. AngularJS has a service factory called ngResource which you can use to do CRUD operation with your RESTful backend application.
Here you just need to define the service factory which will get all notes by calling an ajax request to your http://yourRESTAPIBackendserver.url/notes. Also you can do rest of the CRUD services with that script. This script represents very basic usage of ngResource. So you learn it and try to DYI.
Don’t forget to add the main angularjs library and ng resource service library in your html head tag.
