In a recent tutorial I demonstrated querying a GraphQL API from a Vue.js web application, but what if we wanted to explore something with an Android or iOS mobile application?
In this tutorial we’re going to see how to create an iOS and Android mobile application using NativeScript and Angular and then query a GraphQL API from that application using numerous methods.Read More
As you probably know, Angular is all about building UI components. There are several excellent component libraries out there that you can use to build your own application, such as Angular Material, Clarity or Kendo UI to name a few.
Such libraries provide common reusable components such as tabs, date pickers, collapsible menus, and much more. Still, there’s always a time where we need something more customized and more adapted to the specific needs of our project.
If you ever get in that spot where you want to create a component that might be reused in different projects, or if you want to write components that you would then open-source, this article is for you.Read More
You’re about to release your new Angular web app. It’s a photo sharing site and you want to test it, so you send a link to it to your hacker sister. She’s always messing with your stuff and she found out the URL to your admin page you added to your web app. Before you know it, she’s flushed your database using a button on that admin page that you didn’t restrict access to. Not a problem when using development data - but I’m sure your users wouldn’t be any too keen on a service where they lost all of their data. Let’s fix thatRead More
It’s probably obvious, but most modern applications crave data and in many of those scenarios, being able to visualize the data is a necessity. This is where charting and graphs become valuable within frontend applications. Having attractive charts in your application can make a world of difference and with a convenient library like Chart.js, it isn’t complicated.
If you’ve been keeping up, you’ll remember I wrote a tutorial titled, Use Chart.js to Display Attractive Charts in a Vue.js Web Application which focused on Vue.js. This time around we’re going to see how to include charts in an Angular web application.Read More
Have you ever needed to perform a certain action when the user tries to hit the back button or exit out of your application on Android devices? For example, what if the user was able to back out of your application and you wanted to show a dialog. Or what if you have a video application and you wanted to pause the video when they tap the back button?
Being able to override the functionality of the back button on Android can do great things for your application as long as you don’t abuse it.Read More
Over the past month or so, in my free time, I’ve been working towards creating an affordable hardware wallet for various cryptocurrencies such as Bitcoin. Right now many cryptocurrency enthusiasts are using the Ledger Nano S hardware wallet, but those are very expensive and rarely in supply.
I own several Raspberry Pi Zero and thought it would be a perfect opportunity to take what I know about Raspberry Pi and Golang to create a wallet for a fraction of the price as the industry leading wallets.
We’re going to see how to create a hardware wallet, which I’m calling the Open Ledger Micro, using Golang and a Raspberry Pi Zero.Read More
With Android and iOS so obtainable and development so easy, people often forget the importance of desktop applications. I have a phone and tablet, but I depend on my desktop applications much more. However, the development of these applications are not difficult.
DigiByte isn’t the only popular blockchain on the internet. I’ve also been looking into Stellar because of all the buzz it has been receiving from popular companies like Stripe.
We’re going to see how to create a Stellar XLM wallet for Mac, Windows, and Linux using Angular and Electron.Read More
