Flutter makes building cross-platform mobile applications a breeze. It allows high-performance, beautiful applications to be built for iOS and Android from a single code base. It is also the development platform for Google’s upcoming Fuchsia operating system. In this article, Mike Bluestein introduces Flutter, compares it to other mobile development platforms, and shows how to use it to get started building apps.

Debugging data ranges from simple things like API response latency to monitoring a user’s network health. Without the right framework and tools, the debugging process can be a nightmare. That’s why Akhil Labudubariki developed his own in-house Central Logging Service tool (CLS) to record all important events logged during a session. In this article, Akhil walks through a number of steps and considerations his team made when developing their own in-house Central Logging Service (CLS) tool.

What is Selenium and how can it help you? Well, what if you were told that you could basically automate any task in your browser as if a real person were to execute it? Yes, you read that right. It is possible. In this article Nils Schütte will show you how you can spend less time testing the front end of web applications and still being confident that every feature will work fine. You will find a step-by-step example for automating and testing the login function of WordPress, but you can also adapt the example for any other login form.

The simpler, smaller and lighter an application is, the cheaper and easier it will be to write from scratch. When Nick Gauthier set out to build MeetSpace, he and his team had a familiar decision to make: What’s our tech stack going to be? They gathered their requirements, reviewed their skillset and ultimately decided to use vanilla JavaScript and to avoid a front-end framework. Using this approach, they were able to create an incredibly fast and light web application that is also less work to maintain over time.

With dozens of responsive design frameworks available to download, many web developers appear to be unaware of any except for Bootstrap. Like most of web development, responsive design frameworks are not one-size-fits-all. Let’s compare the latest versions of Bootstrap, Foundation and UIkit for their similarities and differences. These are popular frameworks with piles of features out of the box, making them attractive to many development firms wanting to work with “Bootstrap or a close equivalent.”

One of the upcoming features of JavaScript that I especially like is the support for asynchronous functions. In this article, I would like to show you a very practical example of building a server-side application using Koa 2, a new version of the web framework, which relies heavily on this feature.
First, I’ll recap what async functions are and how they work. Then, I’ll highlight the differences between Koa 1 and Koa 2. After that, I will describe my demo app for Koa 2, covering all aspects of development, including testing (using Mocha, Chai and Supertest) and deployment (using PM2).

How do we make sure the website layout stays responsive and displays correctly on all kinds of devices with various resolutions? In this article, Ivan Shubin will guide you through an interesting new layout testing technique. Using Galen Framework, he will provide a detailed tutorial for writing meaningful generalized layout tests, which can be executed in any browser and on any device and at the same time used as a single source of truth in your design documentation. You will learn how to extend Galen’s syntax with your own language, how to improve the test code and how to turn a layout testing routine into art.
