Getting Started With Capacitor Using React

In February 2018 the Ionic team announced Capacitor. Capacitor allows you to make your frontend builds run everywhere, for example, iOS, Android, Electron and in the browser as a progressive web application (PWA).

Also, Capacitor provides a high-quality API to work with native functions within your apps. For example, you can get access to the camera and it means you still get this access to every platform.

In the official Capacitor documentation you can find a well-described tutorial on how to use Capacitor with Ionic, but in our tutorial, we will check how you can add Capacitor to your existing React app. We will create a simple React app with Capacitor and run it on iOS and in the browser as PWA.

Override The Android Back Button In A NativeScript With Angular Application

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.

We’re going to see how to create a mobile application with NativeScript and Angular that demonstrates overriding the back button on Android, whether that be hardware or software.

Getting Started With GraphQL Development Using Node.js

I’ve been playing around with GraphQL for a little over a month now, just to see if it is worth all the buzz it has been getting when it comes to modern API development. I must say that the more I use it, the more I’m coming to like it.

I recently wrote a few tutorials around getting started with GraphQL using Golang, but being the polyglot that I am, I wanted to see how difficult it would be to accomplish the same in something else, like Node.js. After having made an attempt, I found that it really isn’t any different as it is the same concept, just a different language.

We’re going to see how to get started with developing a web application with Node.js that can be queried with GraphQL rather than the traditional RESTful API endpoint approach.

TPDP Episode #18: Progressive Web Application Development

I’m pleased to announce that the latest episode of The Polyglot Developer Podcast, titled Progressive Web Application Development has been published to all of the major podcast networks.

In this episode, which is the eighteenth on the show, I’m joined by Tara Manicsic who is a Google Developer Expert (GDE) and works for Progress Software, the company behind Kendo UI. We discuss everything from where applications are headed and how they can function effectively as PWAs.

Maintain Data Relationships Through Resolvers With GraphQL In A Golang Application

I recently wrote about getting started with GraphQL in a Golang application, where I discussed the creation of schemas, executing queries, and mutating data, even though it was all mock data. In this example there were queries for related data, but they were constructed in a very independent form.

We’re going to see how to query for related data, similar to what you’d find in a JOIN operation on a relational database, but using GraphQL and the Go programming language.

Scraping Paginated Lists With Node.js, Cheerio, Async / Await, And Recursion

In this tutorial we are going to develop a small Node.js application which will be used to scrape paginated content and export the data to a JSON file. The full source code for the tutorial can be found here.

We will be scraping a list website and saving ten lists per page from the “new lists” section and the final application can be seen below.

Getting Started With GraphQL Using Golang

I’ve been hearing increasing amounts of buzz around GraphQL, a technology that has been around for quite a few years now. In case you’re not familiar, it is a technology for querying API data from a client-front end without having to make numerous requests or receiving unimportant data, both of which may cause negative affects on network latency.

Think of trying to query a relational database. Ideally you write a SQL query for the data you want and you do it in a single request. GraphQL tries to accomplish the same, but from an API consumption level.

We’re going to see how to implement a web application using the Go programming language, but uses GraphQL when working with the data.
