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.Read More
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.Read More
In this tutorial we will build a simple Vue.js application which will demonstrate the power of using Vuex as a central data store, where the data will be asynchronously retrieved using Axios for the API requests.
Sometimes the best examples towards learning a new framework is through a simple user login sample. Login involves many concepts, including forms, data binding, routing, and potentially HTTP to a remote service, all of which are core concepts in any web application.
When working with single page web applications (SPA), chances are you’re going to be using a router or some kind of parent and child component structure. In these scenarios, the parent components probably hold their own functions and variables that may at some point in time need to be accessed by the child component. Take for example an application that has authentication. The parent component might manage the authentication state while the child component might be a login form, secure content, or something else. When logging in, you might need to change the authentication state of the parent. This is just one of many possible examples where the child and parent need to interact.
Earlier this month I had written a tutorial for detecting nearby BLE iBeacon devices using a Raspberry Pi Zero W and an application written with Golang. It was a great example of accomplishing something with Go and very little code.
Scanning for BLE devices is a great use case for Internet of Things (IoT) devices like the Raspberry Pi Zero W, and Golang isn’t the only great language around. I, like many others, do a lot of Node.js development as well.
We’re going to see how to scan for BLE iBeacon devices using Node.js and the popular Node.js BLE (Noble) library.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
