Here is a full stack starter application built on top of my modern login system. https://market.ionic.io/starters/modern-login-and-registration-template

This starter app gets your applications up and running fast with a full login and register system implementing PHP and Oauth for token based authentication. Once the user has logged in they are returned a token in which they can use to make API calls as an authenticated user. They are also given a refresh token to exchange for a new access token.

What do you get?

Full front-end for logging in and registering. Full PHP API back-end to handle login, registration and resource calls. How to get started.

make sure you have a web server running with at least PHP 5 installed. Create a mysql database and run the ddl.sql script against it. Copy the API folder over to the root of web server In the API folder, edit the server.php and database_details.php files and change the database details to yours. All the code commented and is highly customizable. Follow the contacts.php file approach to make calls to your own resources.
