How To Write Automated Tests For Your Ionic App - Part 3

If you've followed along with the previous post, you know how to write unit tests with Jasmine and run them with Karma. In order to write and run end-to-end tests, you will need to use Protractor instead of Karma. Protractor enables you to write tests that interact with your app through the UI. Read More

How To Write Automated Tests For Your Ionic App - Part 2

In this post we'll write unit tests for a controller, in an Ionic app, that deals with asynchronous code and state transitions. It might not be the easiest example to get started with unit testing, but I believe it will set a good foundation for you to write tests for your own app. Read More

How To Write Automated Tests For Your Ionic App - Part 1

Have you ever wasted hours trying to fix something you broke in your code because you made a change, didn't test it properly, and only find out it's broken days later? That happened to me recently while working on an Ionic app. I am a big fan of automated testing, but I kept putting it off for my Ionic project because I didn't have time to get familiar with the testing frameworks for Angular.

How To Debug The White Screen Of Death In Your Ionic App

I probably don't need to explain the dreaded White Screen Of Death, but just in case you haven't seen it yet: it's when your Ionic app is working fine in your desktop browser and then you deploy it to a device/emulator and it doesn't work!

How To Add A Search Bar In The Header On Ionic

Almost every popular mobile app has a search icon in the header and when you click on it, a search bar slides in and allows you to filter the content on the view. Ionic doesn't have a built-in component for that at the moment, but do not despair, there is a plugin for that! Read More

How To Create A Different Tab Layout Per Platform In Ionic

How To Use PouchDB + SQLite For Local Storage In Your Ionic App

I was recently looking into local storage options for an Ionic app. From what I could find, the most popular choice is to use a SQLite database. However, I kept running into people mentioning PouchDB to store data locally and sync it with a server, but I didn't need a server for this particular app. PouchDB also uses a NoSQL approach to database storage, and I come from a SQL background, so I figured I should just go with SQLite. After reading a bit more, I realized that development would be a lot faster and easier with PouchDB, even if you only use it for local storage. Read More

How To Tweak The Keyboard For HTML5 Text Input Fields On iOS

If you're building hybrid apps or mobile websites, you probably already know that the keyboard on the device can be influenced by defining the correct type for your <input> fields. But did you also know that you can change the behaviour of the iOS keyboard, when it comes to auto-correction and auto-capitalization, with attributes? Let's have a look at how to do this! Read More

How To Group Items In Ionic's Collection-Repeat

The Ionic Framework has a collection-repeat directive that you can use, instead of ng-repeat, when you need to display very large lists. I was looking for a way to group items in a collection-repeat list by date, more specifically by the combination of month and year. I had a look at the Ionic Demo for collection-repeat where they group the list by last name. We'll take that code and modify it to do grouping by date. Read More
