Ok, confession time: up until now I haven’t been testing my apps. Well, not properly at least. Of course I play around with my apps and try them on different devices before submitting to the app store, but this is a pretty poor and inefficient testing process. Unit testing on the other hand, is a […]

An Introduction to NoSQL for HTML5 Mobile Developers
If you’ve been hanging around in web land then there’s a good chance you’ve at least heard of NoSQL. It’s a broad term that can mean a lot of different things, but at its core it refers to a database that isn’t a typical relational style database (like MySQL, MSSQL, PostgreSQL and so on). For […]

Building a Review App with Ionic 2, MongoDB & Node
Throughout your adventures in web and mobile development, you may have heard of the MEAN stack, which (aside from sounding pretty badass) stands for MongoDB, Express.js, Angular, and Node.js. All of these technologies work together to allow you to create an application with a frontend and a backend. In this tutorial we will be creating […]

Offline Syncing in Ionic 2 with PouchDB & CouchDB
Since I started travelling around Australia I’ve tried to keep things pretty minimal. I got rid of all the clothes I didn’t need, shoes, kitchen ware, furniture, cleaning products and so on. Basically, I tried to get rid of everything I didn’t need… yet I still have 2 iPhones, an iPad, 3 Android phones, a […]

An Introduction to Lists in Ionic 2
Lists are one of the most common interface elements in mobile applications. They are an efficient way to display lots of information in a small space and the act of scrolling through a list is basically second nature for most mobile users. Facebook uses a list for their news feed, as does Instagram and many […]

An In-Depth Explanation of Providers in Ionic 2
Injectables, Services, Providers – whatever you call them (I like to call them services), they are a critical part of building applications with Ionic 2. Components are the backbone of our applications, they are responsible for what we actually see on the screen, but services play an important role in providing information to our application […]

Creating a Multiple User App with PouchDB & CouchDB
In a previous tutorial I covered how to create an offline application that syncs with a remote database when online. We created a todo application that used PouchDB to store data locally, which synced with a remote CouchDB database. If you’re not already familiar with CouchDB, it is a document based NoSQL database (rather than […]

Part 2: Creating a Multiple User App with Ionic 2, PouchDB & CouchDB
In the last tutorial we discussed some strategies for creating a multi user app with PouchDB and CouchDB, specifically in the relation to the todo application created in this tutorial. If you are unfamiliar with PouchDB and CouchDB I would recommend reading this post before going any further. In short, PouchDB is used to store […]

Building a Hotel Booking App with Ionic 2, MongoDB & Node
A short while ago I wrote a tutorial on how to build a review application in Ionic 2 with the MEAN (MongoDB, Express.js, Angular, and Node.js) stack. Although this was a reasonably advanced tutorial, since it also served as an introduction to MongoDB and creating a backend with Node I kept the application itself pretty […]

Ionic GO – Create a Pokémon GO Style Interface in Ionic 2
When Pokémon GO was released I was in the middle of the Australian outback – the PokéStops, Gyms, and even the Pokémon were few and far between. Although I was missing out on the action a bit, I knew that it was gaining popularity fast but it wasn’t until I got back to a major […]

Using the Web Animations API in Ionic 2
Animations can be the element that sets an outstanding application apart from an average one, but overdone or poor performing animations can degrade the quality of an application. They can greatly improve user experience, or just make things harder for the user. In the web vs native debate, I give little credence to the blanket […]

Create an Animated Login Screen in Ionic 2
In a recent tutorial I covered how to use the Web Animations API in Ionic 2 with Angular 2 animations.

While the last tutorial focused on covering the basics of how […]

Integrating Native Google Maps into an Ionic 2 Application
In the past, I’ve extensively covered how to use the Google Maps JavaScript SDK in Ionic 2, Ionic 1, and even other HTML5 mobile frameworks. These are some of my most viewed tutorials because maps are such a widely used feature in mobile applications, so it’s important that we can do it well. I’ve always […]

Google Maps in Ionic 2: Native or Web?
Last week I published a tutorial on using the native Google Maps SDKs in Ionic 2, and in the past I’ve created many tutorials on using the Google Maps Javascript SDK. In the last tutorial, we discussed some of the differences between using the Cordova plugin that allows us to use the native iOS and […]

Talking Progressive Web Apps with Ionic’s Justin Willis
Generally, when you build an app with a HTML5 mobile framework like Ionic, you package it with Corodva (which wraps the application in a native shell, and provides access to native APIs) and put it up on the app stores to be installed on people’s device – this is a hybrid app. Skip the part […]

Understanding Zones and Change Detection in Ionic 2 & Angular 2
Zones and change detection are an important part of Angular 2, and so it is important to our Ionic 2 application. I figured I understood what was happening at a surface level with change detection, but didn’t really “get it”. I decided to do a deep dive into some research to try and clarify my […]

High Performance List Filtering in Ionic 2
Displaying a list with data is perhaps one of the most common elements of a mobile application, and adding the ability to search and filter those lists is also a common feature. We need to be able to do this in our Ionic 2 applications, and it needs to be done in a way that […]
