Basic Ionic App with JWT authentication and display a database value

I need a basic Ionic App to login with JWT authentication. User credentials are stored in a MySQL/MariaDB Database. This database also contains a lot of weatherdata. The idea is that I develop the display of the data myself. But I need a jumpstart with authentication and the display of one datafield (actual temperature) in the app. Database tables: CREATE TABLE `user` ( `userId` int(11) NOT NULL, `userName` int(11) NOT NULL, `passWordHash` varchar(255) NOT NULL, `email` varchar(255) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8; CREATE TABLE `sensorvalue` ( `stationId` int(11) NOT NULL, `sensorId` int(11) NOT NULL, `dt` datetime NOT NULL, `val` decimal(10,2) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8; I made some mockups with Ionic Creator to get an idea of the look and feel. User should also be able to register (not included in mockup). Client side development: Latest Ionic version Server side development: PHP (NOT node.js).
