Between square inch smart wristwatches and mammoth smart TVs, a responsive website capable of adapting to a wide array of screen sizes and device capabilities is something no one complains about. However, many websites are still plagued by desktop-first design paradigms, or mobile-first paradigms with absolutely no focus on performance. These traditional approaches to responsive web design have various shortcomings. Fortunately, some simple ideas can help solve these problems.

Using React.js props your application's front-end. In particular, testing user interactions and viewing renderings is vastly improved with React UI testing.

In-memory data collection manipulation is something that we often need to do in data-centric reporting and visualization applications. When needed, we often tend to resort to complex loops, list comprehensions, and other suboptimal means, which can easily end up being a huge mess of hard-to-maintain spaghetti code. Supergroup.js is an in-memory data manipulation library that can be used to solve some common data manipulation challenges on limited datasets.

In this article, I'll go through some of the interesting features and libraries that are available to use with React. Even if you don't plan on using React, taking a look at its ecosystem is inspiring. You may want to simplify your build system using the powerful, yet comparatively easy to configure, module bundler Webpack, or start writing ECMAScript 6 and even ECMAScript 7 today with the Babel compiler. So, let's explore the React ecosystem!

Programming is about having fun and enjoying the process of creating something cool. That is why we decided to build a bot-vs-bot game platform around Battleship and make it open source. In this article, we take a look at the code and mechanics of the extensible engine behind this platform.

While Ruby has Rails and Python has Django, the dominant application development framework for Node has yet to be established. But, there is a powerful contender gaining steam: LoopBack, an open source API framework built by StrongLoop, the creators of Express. Let's take a closer look at LoopBack and it's capabilities by turning everything into practice and building an example application.

Ember.js is a comprehensive framework for building complex client-side applications. But, as with any advanced framework, there are still pitfalls Ember developers may fall into. With the following post, I hope to provide a map to evade these. Let's jump right in!!

Bootstrap is a powerful toolkit. It comes bundled with basic HTML and CSS design templates that include many common UI components. Most of the important pitfalls are mentioned in the Bootstrap documentation, but still some mistakes are pretty subtle, or have ambiguous causes. This article outlines some of the most common mistakes, problems, and misconceptions when using Bootstrap.
