Test Password Strength Using Regular Expressions in a NativeScript Mobile Application

Recently I released some content around form validation within a NativeScript application that uses Angular. This is great as you can use it to check your form for errors based on any number of criteria. However, what if you wanted to guide your users through a form process rather than validating the data? An example […]

Have Web Standards on Mobile Caught Up to Phonegap in 2017? Pt. 2

In my previous article, I took a look at the "core" set of PhoneGap/Cordova plugins and how well (or how poorly) they are supported now via web standards. The idea wasn't to say you never need go hybrid, but that you may not necessarily have to go hybrid, which was one of the core principles […]

Generating Splash Screens and Application Icons for NativeScript Mobile Apps

So you've created a fantastic mobile application for Android and iOS using NativeScript and you're getting ready to publish it to Google Play and iTunes. This is great, but more work probably needs to be done. For example, you probably don't want to use the stock NativeScript application icons – also called launcher icons – […]

Form Validation in a NativeScript Angular Mobile Application

Not too long ago I wrote a tutorial to compliment the Angular documentation for form validation in an Angular web application. This was a follow-up to an old AngularJS tutorial I wrote for form validation in an Ionic Framework 1.0 application. As you probably know, I'm a huge fan of NativeScript, and while NativeScript supports […]

Using CodePush with NativeScript

Would you like to be able to dynamically update your NativeScript app that is already deployed to a phone and/or a tablet? Think about it for a moment… You could just push a quick update without having to go through Google Play or Apple's App Store. This is where the nativescript-code-push project comes in. It enables your […]

Why Do You Need NativeScript?

There are more ways to build mobile apps than there are Nicholas Cage DVDs in the bargain bin at your local Walmart. Because there are so many choices, it can be difficult to tell which frameworks will improve your development processes, and which will turn out worse than Nicholas Cage’s twelve <=10% Rotten Tomatoes movies. […]

Progressive Web Apps — Yeh or Meh?

The impetus for this chat came when our very own Burke Holland dropped this hot take in the Progress DevRel Slack: “I'm still so meh on PWAs that I can't even.” For those unfamiliar, Progressive Web Apps, or PWAs, is a Google-led initiative to bring native app features such as home screen access and push […]

Using XAML in Xamarin.Forms – Part 2: Accessing Static Data

The first article in the Using XAML in Xamarin.Forms series, looked at how XAML increases the legibility of the user interface code over C#, how to set both member and attribute properties, and how to setup event handlers for user interface events. In this article, I want to explore how to access data from XAML. […]

How to use Firebase Cloud Messaging in a NativeScript Angular Mobile App

An often critical part of mobile application development is the requirement of being able to receive notifications from a remote source, often referred to as push notifications. Previously I had explored how to use local notifications in a NativeScript application, but these are triggered based on a schedule within the application itself, rather than a […]

Have Web Standards on Mobile Caught Up to Phonegap in 2017? Pt. 1

Anyone who has attended a presentation on PhoneGap (or Apache Cordova) since its inception has probably heard this famous statement: "The ultimate purpose of PhoneGap is to cease to exist." In 2012, Brian LeRoux wrote up the PhoneGap Beliefs, Goals and Philosophy that stated as much: This is not some self-defeating far planned suicide, but […]
