Remixing, behavioral testing, server-side rendering, and more
2022 has just begun and there are a lot of exciting things on the radar if you’re using React Developer. Whether these are things that have already been released or that still need to come out, there’s a lot to look forward to. It certainly isn’t going to be a boring year in the world of React development and I personally am more than excited about everything we know 2022 will definitely bring. This article will cover topics that I believe will make a huge impact on the field of React development or the concepts every React developer should be looking for this year.
Thrilled for far too long, Remix has finally been officially launched at the end of 2021. Backed by some of the greatest names the field has to offer, Remix is marketing itself as a full-stack web framework based on web essentials with a modern user experience as a focus.
At the core are Remix Rack concepts such as performance, incremental optimization, nested paths, parallel data loading, customizable levels of error handling, and per-track CSS loading and unloading. For any front-end developer, Remix will be like a box of chocolates waiting to be unpacked. And 2022 will be the year for that.
To learn more about Remix or to start using it, I recommend checking out their v1 blog post which will point you in all the good directions.
One of the most exciting things about React is React 18. It includes a lot of new features, APIs, and much more. But one of the most important aspects is the extra focus on server-side rendering and all of the off-the-shelf possibilities.
Although it is indeed possible to have a server-side rendering using various frameworks such as Next.js and Gatsby, the out-of-the-box support for React has always been limited. But with the addition of features like suspense, HTML streaming, and selective hydration, a world of opportunities will open up.
The length of this paragraph certainly does not reflect how excited I am about this, but going deeper into this topic would warrant a full article on its own. If you’re not sure what server-side rendering means, what the difference is by client-side rendering, or what the above features mean, now is the time to investigate them in preparation for React 18!
If you thought there would be only one big theme as part of React 18, the React team has a very pleasant surprise for you. Another very exciting feature coming in the next version of React is the so-called synchronous rendering mechanism.
To give you a very brief summary of what concurrent rendering is: One of the problems with React in its current form is that all state updates are concurrent. This means that React has to deal with them one by one, and finish the current one before it can pick up a new one. In many cases, that’s perfectly fine. But when some updates have more priority or urgency than others, this can become a problem.
This is where synchronous viewing comes in. It allows React to process multiple updates simultaneously. However, this does not mean that React will perform many state updates simultaneously. Alternatively, he can decide to pause the current state update he’s working on and choose another more urgent one. Later, React can decide to resume the paused state update or drop it altogether.
Honestly, this is the thing I look forward to most in 2022. Simultaneous rendering opens up a whole new world of possibilities for React developers to improve the real and perceived performance of their front-end applications. It allows us to work with React in a completely different way and forces us to change the way we currently think about displaying streams.
To learn more about anything related to concurrent rendering, I recommend checking out the React 18 announcement. It includes everything necessary to begin understanding concurrent rendering, such as the concepts behind it and how to subscribe to it. Actually, synchronous rendering is not a single feature but it will come as a set of APIs that will allow React developers to choose different parts of their applications in synchronous view.
In React, we’ve seen a huge shift in the way components are tested over the past years. Whereas previously it was primarily focused on unit tests, the current focus has been more towards making sure your tests are as representative as possible to users’ experience – behavior testing.
Currently, behavior testing has become the industry standard for testing in React development. With the ever-increasing adoption rate, the popularity of the React test library, and even its mention in the official React documentation, it’s unlikely that behavior testing will leave the scene soon.
Even if you don’t use the React test library, it is possible to adopt behavior testing as a concept. In practice, Behavior Testing is not related to any framework or library. With the right approach and thinking, you will be able to write behavior tests using Enzyme, Jest, Mocha, etc. As a React developer, implementing proper behavior testing will be an invaluable and essential tool in your skill set.
While the above topics are very interesting, large and relatively unknown to many React developers, there are also quite a few others that deserve honorable mention. These technologies are still very interesting in 2022 but have been around for quite some time already. Therefore, the chances of encountering or working with them are greater if you are in the field of React development.
If you’ve been developing React for a long time already, you’ve probably heard of the terms “design system” or “component-driven development.” And if you’ve ever looked at any of those, you’ve very likely come across Storybook. The tool is now open source An essential element in developing an organized and reusable user interface.But even with its current popularity, the great team behind Storybook isn’t slowing down any time soon.With active maintenance and mind-blowing features in every release, Storybook is always a tool to look out for if you haven’t You haven’t done it yet.
Even after so many years, the React development field still has a lot to offer. Whether you are a seasoned veteran or a newcomer to the game, there are always things to look out for in the world of React.
Looking to the future, I am very excited about 2022 and all that it will bring us in terms of new technologies and concepts. The introduction of Remix will change the way we approach front-end development and the realm of React frameworks. React 18 will make it very easy to implement an essential part of web development in server-side rendering, while introducing an entirely new way to improve the performance of interface applications in the form of concurrent rendering.
And if that’s not enough to get you excited, there’s also still a whole world to explore for behavior testing as it establishes itself as a testing standard, TypeScript as the primary tool for maintaining React projects of any size, and Storybook as an essential tool for promoting structured user interface development and design collaboration. .
