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 […]
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 […]
A Primer on CSS 4 Variables for Ionic 4
Apparently, good things come in 4’s (sorry, that was the best I could do). Another significant addition to Ionic 4 is going to be support for CSS4 variables, which will now play the primary role in Ionic’s theming approach. In this article, we are going to take a brief look at what CSS4 variables are […]
Adding Icons & Splash Screens (Launch Images) to Capacitor Projects
Generating icons and splash screen images ends up being a much more difficult task than you might anticipate before doing it for the first time. The difficulty stems from the fact that there are a bunch of different devices that your application could be running on, a lot of which will have different resolutions/pixel density. […]
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 […]
Ionic Framework Is Fast (But Your Code Might Not Be)
I don’t want this article to come across as a self-righteous rant, or that I’m attacking people who have made statements like the ones I will use as examples in this article. The last thing I want to do is sound elitist or fan the flames of framework wars. So, I will precede this article […]
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 […]

Integrating an Ionic Application with a NodeJS Backend
Developing on the client side with Ionic is a pleasure. It’s based on the web tech we know and love, and it runs straight in the browser so we can dive straight into the development in minutes. You can only get so far developing purely on the front-end/client-side, though. If your application needs to provide […]
Creating a Facebook Style Reaction Button in Ionic
Near the start of 2016, Facebook released “Reactions” which gave users a way to express themselves more deeply than just with a single “Like”. Rather than adding it a bunch of new buttons for the reactions, Facebook stayed with a single “Like” button that would then display more options when the button was held down: […]
Launching a Progressive Web App (PWA) with Ionic
About a week ago I launched the early access for Elite Ionic. This is my latest course for Ionic, and it is focused on teaching advanced Ionic concepts. Typically, when I release any paid content it is in the form of an eBook, but this time I wanted to do something a little different. Elite […]
Integrating a Backend with Ionic
I often see questions like “How do I use PHP/MySQL in Ionic?” or “Does Ionic work with X backend?” – these are reasonable questions, but it indicates a big misconception as to how integrating a backend with Ionic works. The technology that is used on the backend is completely irrelevant, as the backend and the […]
Uploading a Production PWA with Ionic
In a recent tutorial, I covered how to create a Progressive Web application with Ionic using the “bare minimum” steps. PWAs are an in-depth topic, but that tutorial covers the minimum steps required to create something that would be considered a PWA. In this video tutorial, I wanted to cover the steps you need to […]
The Bare Necessities: Progressive Web Apps in Ionic
You’ve probably heard of Progressive Web Applications by now, but if you haven’t then you may want to give this a read. In short, they are all about giving applications made available through the web a more native-like experience. This means at a minimum that they should work offline, and can be installed onto a […]
What Does Lazy Loading Do in Ionic?
Lazy loading has been around for a while now, and it’s likely that you’ve had at least some experience with it if you have been building Ionic applications recently (the Ionic CLI page generator uses lazy loading by default). If you aren’t familiar with lazy loading, then you might be interested in checking out this […]
When to Use Providers / Services / Injectables in Ionic
A concept you will quickly come to terms with in Ionic is the concept of a page. A page is just a normal Angular component that we use to display a particular page in our application. We might have a page for displaying a list of users, and so we have a component called UserListPage […]
