Web Front-end

In this article, I will show that unit testing itself is quite easy; the real problems that complicate unit testing, and introduce expensive complexity, are a result of poorly-designed, untestable code. We will discuss what makes code hard to test, which anti-patterns and bad practices we should avoid to improve testability, and what other benefits we can achieve by writing testable code. We will see that writing testable code is not just about making testing less troublesome, but about making the code itself more robust, and easier to maintain.

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.

Building robust web applications is often a lot about choosing the right tools. Doing so with a combination of tools that ensure both a modern, flexible front-end, and a solid, reliable back-end is something everybody wants. This article demonstrates exactly that trick by combining AngularJS and Play Framework to build a simple blog application.

Deploying instances of a web application to one or more servers manually can often be a monotonous process, and take up a significant amount of your time. With little effort, it is possible to automate the process of deploying your web application with almost zero human intervention. This article outlines a simple approach to automating web application deployments using GitHub webhooks, buildpacks, and Procfiles.

Backbone.js equips the developer with an array of tools that are minimal but extremely flexible. This gives developers the option to design the applications the way they want, but also introduces a number of way things can go wrong. This article outlines a few common mistakes that Backbone.js developers can make, and how they may avoid them.

Log files may very well be one of the most underestimated and underutilized tools at a developer’s disposal. Beyond their value for debugging, with a bit of creativity and forethought, logs files can be leveraged to serve as a valuable source of usage information and analytics. In this article, In this article, Toptal engineer Ilya Sanosyan provides a practical guide to maximizing the value we get from our logs.

AngularJS is a very powerful framework. It is the third most starred repository on GitHub. It is not difficult to start using, but the goals that it is intended to accomplish demand comprehension. No longer can we ignore memory consumption, because it will not reset on navigation anymore. This is the vanguard of web development. Let’s embrace it!

C++ is a general purpose programming language that offers great flexibility when it comes to system programming and application development. The language, however, comes with some pitfalls requiring attention from developers to ensure quality programming. This article explains how ten of the most common C++ developer mistakes can be avoided.

Developers often automate certain repetitive and tedious tasks to save time as well as to stay focused on the task at hand.

This article demonstrates how simple and easy it is to use Gulp as a build tool.

Node.js, the cross-platform runtime environment, has seen its fair share of praise and criticism for what it offers to developers. Often, reasons for such criticisms are rooted in how developers use/misuse the language.

This article explores ten common mistakes that Node.js developers make and how to avoid them.

Meteor makes developing web applications simple. It’s easy to learn, and comes with a pre-built arsenal of powerful functionalities. In this article, we will walk through a detailed tutorial for building a simple real-time web application.

Authentication is one of the most important parts of any web application. For decades, cookies and server-based authentication was the easiest solution. However, handling authentication in modern Mobile and Single Page Applications can be tricky and demand a better approach. One of the best known solutions to authentication problems for APIs is the JSON Web Token (JWT).

In an attempt to make web applications a lot more dynamic, front-end Javascript frameworks like Angular.js, Backbone.js and Ember.js have gained a lot of popularity. However, these frameworks often require a back-end application to be useful, so they are used in conjunction with web frameworks like Ruby on Rails and Django.

On the other hand, Volt is capable of managing the back-end and a dynamic front-end; since both functionalities are tightly integrated into its core.

Java, a sophisticated programming language, has been dominating a number of ecosystems for quite a while. Portability, automated garbage collection, and its gentle learning curve are some of the things that make it a great choice in software development. However, like any other programming language, it is still susceptible to developer mistakes.

This article explores the top 10 common mistakes Java developers make and some ways of avoiding them.

In our previous post on the GWT Web Toolkit, we discussed the strengths and characteristics of GWT to mix Java and JavaScript libraries seamlessly in the browser. In today’s post, we would like to go a little deeper and see the GWT Toolkit in action. We’ll demonstrate how we can take advantage of GWT to build a peculiar application: an augmented reality web application that runs in real time, fully in JavaScript, in the browser. We’ll focus on how GWT gives us the ability to interact easily with many JavaScript APIs, such as WebRTC and WebGL, and allows us to harness a large Java library, NyARToolkit, never intended to be used in the browser.
