Recently, I published a tutorial on using ThreeJS with Ionic to embed virtual reality content into a mobile application using WebVR. This tutorial is going to be somewhat similar, we will still be making use of ThreeJS and WebGL, but we will be creating an augmented reality experience in an Ionic/Angular application. If you are […]
Using BehaviorSubject to Handle Asynchronous Loading in Ionic
It is common in Ionic applications (and Angular applications more broadly) to create some kind of service to handle loading data from some source. This might be from a local JSON file, local storage, a remote database, or some other kind of data store. The idea is that the service handles any of the complexities […]
Understanding How Slots are Used in Ionic 4
As you may know by now, the big change in Ionic 4 is that all of Ionic’s components are becoming web components. Since web components are a feature of browsers, and not of specific frameworks, this will allow Ionic to work with any framework or no framework at all. The basic idea behind Ionic’s components […]
Converting Ionic 3 Push/Pop Navigation to Angular Routing in Ionic 4
Most of the changes required for upgrading from Ionic 3 to Ionic 4 are going to be simple find and replace style changes – things like changing <button> to <ion-button> and ionViewDidLoad() to ngOnInit(). Although it will look slightly different, the code that you are using in Ionic 3 will more or less look the […]
Creating a WebVR Experience in an Ionic/Angular Application
I’ve become absolutely fascinated with WebVR recently. The fact that you can access an immersive virtual reality experience powered by a web browser on your mobile phone just blows my mind. I picked up a Google Pixel 2 XL and a Google Daydream headset to experience and develop for WebVR, which provides a nice and […]
Creating a Theme Switcher Service in Ionic Using CSS4 Variables
A couple of weeks ago I released an article about how CSS4 variables would be used in Ionic 4. In that article, I discussed how using CSS4 variables for theming allows you to modify these variables at runtime because unlike SASS variables which need to be compiled, CSS4 variables are supported natively by the browser. […]
Create a PWA with Angular Service Workers in Ionic 4
I have written several articles on the topic of Progressive Web Applications (PWA) in Ionic before, including this one which provides a basic overview of the concept of PWAs and how to create one with Ionic. I would recommend reading that article if you need a little more background on what PWAs and service workers […]
Faster Boot Times with Lazy Loaded Web Components in Ionic 4
In this article, we are going to take a look at a feature introduced in Ionic 4 that will reduce the initial load times of our applications. Before we get into discussing that, though, I want to highlight that when it comes to performance we can’t just rely on the framework. I published an article […]
Creating a Tabs Layout with Angular Routing and Ionic 4
Recently, I published a tutorial that talked through how to use Angular routing in an Ionic/Angular application when Ionic 4.x is released. Although using Angular style routing is not required if you want to upgrade to Ionic 4, there are a lot of benefits to doing so (and some features that were available with standard […]
Prevent Access to Pages in Ionic with Angular Route Guards
In a previous tutorial, I covered how we would implement Angular routing in an Ionic 4.x application. When Ionic 4 is released, there will be more of a focus on using the baked in Angular routing, rather than Ionic’s own push/pop style routing (this style of navigation will still be available, though). In this tutorial, […]
Using the Capacitor Filesystem API to Store Photos
When we take a photo on an iOS device, the resulting file is stored inside of a temporary folder called tmp. If we use the Camera API to retrieve a photo, the resulting URI will look like this: If we are interested in long-term storage then this isn’t the best solution. The way you approach […]
Implementing a Master Detail Pattern in Ionic 4 with Angular Routing
Earlier this week, I published an article that discussed how and why you should use Angular routing with Ionic 4.x. To summarise, the main points from that article were that: Angular routing primarily relies on defining a bunch of routes that link to specific components/pages, and then using the current URL to determine which route […]
Using Angular Routing with Ionic 4
Recently, I published an article that talked through some of the expected changes for the upcoming Ionic 4.x release. Most of the changes that will be introduced are behind the scenes, and there won’t be that many changes required for updating your Ionic 3.x applications to 4.x. Ionic 4 has not officially been released yet, […]
What to Expect When Ionic 4 Is Released
The Ionic team has been busy working behind the scenes to finish the release of Ionic 4.x, which we should hopefully see an alpha release of before too long. We’ve talked about the benefits of Ionic 4 in the past. In this article, I want to focus on how the release of Ionic 4 will […]
Publishing a Web Component Using Stencil (And Using It Anywhere)
Over the past couple of weeks we have explored creating custom components within Ionic/Angular, and creating custom web components using Stencil. Although both behave very similarly, the key difference between creating an Angular component, and a Stencil component, is that Stencil generates generic web components that can be used anywhere. Angular components can only be […]
Using Google Maps and Geolocation in Ionic with Capacitor
Google Maps integration is consistently one of the most popular features of mobile applications. I’ve published tutorials on how to use Google Maps with Ionic many times in the past, but I wanted to revisit the basics again now that some time has passed. Previously, I have used Ionic and Cordova to build a Google […]
Automatic Scroll to Bottom Chat Interface with Mutation Observers in Ionic
It is common in chat interfaces to have the latest messages displayed at the bottom of the screen, and for the screen to automatically scroll to the latest message when a new one is added. This is a feature I added to the chat application that is built in the last module of Elite Ionic, […]
Improving the UI/UX of an Ionic Component
In this tutorial, we are going to improve upon the flash message service that we created in the last tutorial. I offered some suggestions for improving the service at the end of that tutorial which included: Allowing for different messages styles (success, danger, warning, etc.) Displaying a bar to indicate how long the message will […]
Creating a Flash Message Service in Ionic
You will often run into circumstances in your application where you want to send some kind of alert to the user. You might want to let them know that they have lost their Internet connection, or that a post failed to upload, or that a photo has finished successfully uploading. In terms of the built-in […]
Adding CAPTCHA to Ionic with NodeJS Middleware
When I built the Elite Ionic course, I built it as a PWA using Ionic. Anybody who signs up for the course can log in to the application and browse through the various modules. When people create accounts, they need passwords, and when passwords are involved they will inevitably be forgotten at some point. For […]

Building a Time Locked Advent Calendar in Ionic
As a kid, advent calendars were one of my favourite Christmas traditions. There was something special about ripping open that perforated cardboard each day and eating chocolate first thing in the morning. As an adult, I would prefer one of those whiskey advent calendars, but 24 little bottles of bourbon work out to be quite […]
