Starter Ionic Application Template w/Parse Integration

Updated: Dec 14, 2018




Overview

This sample application is provided as a starter to get your Ionic Framework andParse Application up and running easily. Most of the fuss in these applications is figuring out login and account creation… This template solves that for you with a pattern that then can be utilized for a full-blown application; this is not a throw-aways tutorial.

We have seperated out the templates, controllers, and services into a format that will be sustainable for your final solution.

Setting Up Parse Configuration in the Starter App

See the Parse.com website for Getting Started.

The critical information needed after configuring your application is the applicationId  and the javascriptKey  which are needed for the configuration section of the ionic application

Parse Configuration Screen for Application

Using the values from the Parse Console, set the properties in the app.js file section shown below




Starter App Project Structure

The starter app is a Two-Tab based app with a Login Screen and an Account Creation Screen. The application will create Parse Users for you after it is configured properly.

The first Tab is setup as a list view that when a used clicks on an item in the list a detail screen is rendered. The ui-router routes are already configured for this application behavior.

List View

Detail View

The second Tab in this setup as a “Settings Screen” that will pass in the User Object from Parse when the user selects the Tab.

Application Settings View

The file structure is such that all of the user specific functionality is www/js/user/controllers.js  for controllers andwww/js/user/services.jsfor services & factories. The associated views are in www/templates/user/login.html andwww/templates/user/signup.html .


UI-Router and Resolve

The simple way that we ensure the user is logged into the application is by using the abstract state tab , this state uses resolve functionality from ui-router  to determine if the Parse User Object is available by callingUserService.init() . If the promise is resolved successfully, then we have a User object and the application can move forward.

If the UserService.init()  function cannot resolve successfully, it returns the error  noUser . Whenever the ui-router  fails to route properly, an error is generated  noUser.

We listen for the $stateChangeError  and if it is in fact the noUser  error then we route to the Login Screen using theapp-login  state of the ui-router .

Since the tab  state is abstract  all child states of must also have successfully resolved the parent state, this ensures the user in logged in before executing any state of the application


Parse Service in Ionic Framework

It was important to me to not include the Parse functionality directly in the controller like so many of the other tutorials out there since in is not a best practice. But once you get into the service, you will see that the service is simply a wrapper around the specific Parse Javascript API calls.



Logging in a user is even more straight forward
