Unit Testing In A Telerik NativeScript Mobile App

Unit testing! It’s something that we as developers all understand the importance of and implement in every project, right?

cough

Anyway… did you know NativeScript supports unit testing out of the box? It’s true!

By unit testing your application, you can ensure that any changes you’ve made to your code are working properly and that they haven’t broken any previous code. You could also integrate it into your Continuous Integration process and automate the running of your tests on a regular basis, or on each code check in!

TPDP Episode #4: What is All This Mobile First, Offline First, and API First Jargon?

There are a lot of “first” approaches circulating in the development and design space at the moment, but what does all this jargon mean? In this episode of the Polyglot Developer Podcast, guest speaker William Hoang and I are going to explore some of the common practices such as mobile first, offline first, and API first. I’ve broken Episode #4: What is All This Mobile First, Offline, First, and API First Jargon? into the following parts:

• What is the Mobile First Approach?
• What is the API First Approach?
• What is the Offline First Approach?

At the end of the podcast William and I bring everything together and explain how all of them are necessary in modern application development.

Implement A Barcode Scanner Using Telerik NativeScript

So you’re getting some fancy new features into your NativeScript Android and iOS application. A feature I always find to be useful is having a barcode scanner within my app. Barcodes are a convenient way to pass around information without having to type it in. With NativeScript we can easily add scanning features to our application.

We’re going to see how to create a NativeScript Android and iOS application that can scan different types of barcodes.

Monetize With Google Admob In A NativeScript Mobile App

So you just made a fancy new NativeScript Android and iOS application and you’re looking to earn a little cash. There are many solutions out there, for example you could include InAppBilling or list your application as a paid application. You can also include advertisements in your application using various ad networks such as Google Admob.

We’re going to take a look at how to include Google Admob in a NativeScript iOS and Android mobile application with the intent of earning a little extra money. Now this is going to use vanilla NativeScript. If you’re looking for instructions on how to do this with Angular, check out the guide I wrote here.

Access The Native Device Clipboard In Telerik NativeScript

Have you ever wanted to copy something from your application to the native device clipboard? Maybe you want to copy contact information from a list of elements so you can paste it elsewhere. I recently wrote a post regarding social media sharing with Telerik NativeScript that will let you share to the clipboard, but that is a little overkill. Specially because there are actual clipboard APIs that don’t rely on social media sharing.

We’re going to see how to use the native device clipboard features in NativeScript to copy text to the clipboard and later obtain it.

Implement Social Media Sharing In A NativeScript App

Every app lately has some social media aspect to it. Most commonly, apps will allow you to share some kind of data, whether it be an image or text, to social media networks such as Facebook or Twitter. Sharing via email or SMS message still is classified as social sharing. When building NativeScript Android and iOS applications, sharing data isn’t complicated.

We’re going to see how to share image data and text data on social media networks via a Telerik NativeScript Android and iOS mobile application.

Add Touch ID Authentication Support To Your NativeScript App

Being able to authenticate within a mobile application using your fingerprint offers a certain convenience that is of huge benefit in modern applications. Using the iOS touch id, doors can be opened in the land of application security and since Telerik NativeScript can interface with native APIs and features, touch id becomes available for use within our JavaScript based application.

We’re going to see how to show secure content within our application, only accessible after successfully authenticating using a fingerprint and the iOS touch id features.
