What if you spend the unproportionate amount of time to support an outdated system?
The typical answer to such a problem is the migration of the application. However, all of the front-end frameworks are different. In this article, Denys Mishunov will show you “Frankenstein Migration” which is a new, framework-agnostic approach to the process of migration that allows using the same mechanism to migrate to pretty much any framework of your choice.

As with many other topics in software development, testing and test driven development are often made needlessly complex in theory and implementation by placing too much emphasis on learning a wide array of testing frameworks. In this article, Ryan Kay will revisit what testing means by a simple analogy, explore concepts in software architecture which will directly result in a reduced need for testing frameworks, and some arguments as to why you might benefit from an attitude of minimalism for your testing process.

In this article, Ben Frain concludes a three-part series about the trials and tribulations of designing and writing a basic web application with vanilla JavaScript. In part one he covered the why, part two dealt mostly with the how and this part concludes by looking at how the project was drawn to a close and what was learned from the experience. Ben will cover turning a basic web application into a Progressive Web Application (PWA) and ‘shipping’ the application before looking at the most valuable lessons learned by making the simple web application In/Out.

In the first article of this series, your author, a JavaScript novice, had set themselves the goal of designing and coding a basic web application. The ‘app’ was to be called ‘In/Out’ — an application to organize team-based games. In this article, Ben Frain is going to concentrate on how the application ‘In/Out’ actually got made.

You don’t need to be a Computer Science graduate or know a JavaScript framework to create a Progressive Web Application. With some HTML and CSS knowledge and basic competency with JavaScript, you have all the skills you need. In three parts, Ben Frain is going to share the journey of designing and building a simple Progressive Web Application called ‘In/Out’, built without a framework. You can view it here.

Let’s say that you wish to compile a list of the Oscar winners for best picture, along with their director, starring actors, release date, and run time. Using Google, you can see there are several sites that will list these movies by name, and maybe some additional information, but generally you’ll have to follow through with links to capture all the information you want. Scrapy is a popular open-source Python framework for writing scalable web scrapers. In this tutorial, Daniel Ni will take you step by step through using Scrapy to gather a list of Oscar-winning movies from Wikipedia.

DOM changes can be frequent, and as a result, there are instances where your app might need to respond to a specific change to the DOM. Monitoring for changes to the DOM is sometimes needed in complex web apps and frameworks. By means of explanations along with interactive demos, Louis Lazaris will show you how you can use the MutationObserver API to make observing for DOM changes relatively easy.

The popularity of Vue.js shows no signs of slowing down, with a huge amount of credit being due to the framework’s progressive approach. One of the key advantages of Vue.js is that it plays nicely with other code: it is easy to embed progressively into other applications, but it is also easy to wrap up non-Vue code into Vue. In this article, Kevin Ball explores this second advantage, covering three distinct types of third-party JavaScript and ways to embed each of them in Vue.

Have you ever considered whether CSS Grid can actually replace the need for CSS frameworks or third-party component libraries? In doing so, Rachel Andrew discovered a range of reasons people use a third-party framework and the positive and negative things about doing so. In this article, you will discover that the reasons for using frameworks are varied, and not simply centered around use of the grid system contained in that framework. We hope that by unpacking these reasons, Rachel can help you to make your own decision, in terms of what is best for the sites and applications that you are working on, and also for the team you work with.

Frameworks such as Espresso and Mockito provide easy-to-use APIs that make writing tests for various scenarios easier. The important thing to consider while writing tests is the units of responsibility that emerge as you design the new feature. The unit test should cover all possible interactions with the unit, including standard interactions and exceptional scenarios. In this article, Vivek Maskara will cover the fundamentals of testing and frameworks which developers can use to write unit tests.
