React native architecture upgrade

React Native's New Architecture is Here!!!

React Native has finally received a significant upgrade with its new architecture. This is a major breakthrough, and it's going to change the way we build mobile applications. In this article, we'll dive into the details of this new architecture and explore what it means for developers.

Terrible News for Firebase Users

Before we dive into the new architecture, let's talk about Firebase. The author of the video is a big fan of Convex, a backend platform that allows you to define a query with just five lines of code. With Convex, you can use the power of React and TypeScript to build your backend, without having to worry about the complexity of infrastructure. Convex also offers live sync, which means that your data will be automatically updated whenever there's a change.

The New Architecture

The new architecture is finally here, and it's been a long time coming. React Native 0.76.1 is the latest version, and it's packed with exciting features. One of the most significant changes is the way updates are handled. With the new architecture, updates are now handled in chunks, which means that the UI won't be blocked by updates. This is a huge improvement, and it's going to make a big difference in the way our apps feel.

Urgent and Non-Urgent Updates

The new architecture also introduces the concept of urgent and non-urgent updates. Urgent updates are updates that need to happen immediately, such as when a user interacts with the UI. Non-urgent updates, on the other hand, can be delayed if they're not critical to the user experience. This means that the app will feel more responsive, and the user will have a better experience.

Automatic Batching

Another exciting feature of the new architecture is automatic batching. This means that updates will be batched together, which will reduce the number of updates and make the app feel more snappy. This is especially important for apps that have a lot of complex UI components.

Solving the Problem of Blocked Updates

One of the biggest problems with the old architecture was that updates could be blocked by other updates. This meant that the app could feel slow and unresponsive. The new architecture solves this problem by introducing a new way of handling updates. With the new architecture, updates are handled in chunks, which means that the app won't be blocked by updates.

Kraken App's Performance Boost

The Kraken app, a popular cryptocurrency trading platform, has seen a significant performance boost with the new architecture. According to the author, the app is now 5.3 times faster than before, thanks to the new architecture.

Conclusion

In conclusion, the new architecture of React Native is a game-changer. It's packed with exciting features that will make our apps feel more responsive and snappy. With automatic batching, urgent and non-urgent updates, and a new way of handling updates, React Native is now more powerful than ever. If you're a React Native developer, it's time to start exploring the new architecture and seeing what it can do for your apps.
