No need to say that Reactjs is now one of the most demanding javascript library using and loved by most of the technology companies and so developers. As ReactJS 19 approaches its release, several exciting new features are expected to empower developers to create even more dynamic and efficient web applications. In this document, I am trying to explore some of the anticipated features of ReactJS 19.
1.Own Compiler : In new react 19 we are going to get its own compiler which will compile and convert the react code into regular javascript code. This will make reactjs 2 times faster its execution and boost its power or rendering.
2. Concurrent Rendering: This new version of Reactjs will improve in concurrent rendering capabilities. Concurrent rendering allows React to work on multiple tasks simultaneously, making UI updates smoother and more responsive. This feature enhances the overall performance of React applications, especially for complex user interfaces with high interactivity.
3. Improved Server-Side Rendering (SSR): Server-Side Rendering is crucial for delivering fast initial page loads and improving SEO for web applications.Once major goal of ReactJS 19 is to enhance SSR capabilities further, optimising the rendering process on the server-side. This improvement will lead smooth running of application, make the application run faster and user will gain better experience when using this application.
4. Suspense for Data Fetching: Suspense is a powerful mechanism introduced in previous versions of React for handling asynchronous operations such as data fetching. The new React is expected to redefine and rescale the suspense mechanism and this will help developers in data fetching and doing asynchronous operations more effectively.
5. Asset loading faster: This is probably one of the best feature in new Reactjs where necessary assets like images or videos or files will load in background when user is doing some other important work in page. In that way it will minimize the loading time of webpage or reduce time to load an image.
6. Built-in Error Boundaries: Error boundaries enable developers to handle errors that occur during the rendering process, preventing the entire application from crashing. Expected that ReactJS 19 will introduce built-in error boundaries as a standard feature and helps developer to gain more flexibility in error handling and showing error page in more controlled ways.
7. Improved DevTools Integration: React Developer Tools is an essential to developers for debugging and profiling React applications during development. ReactJS 19 aims to enhance DevTools integration, providing developers with some more features and develop existing controls which will help developers to gain more power in debugging and measure application perforce as well.
8. Context API over Redux : State management is one challenge in React which we solve using Redux and context API. Normally redux we used to mange global state of an application and context api do the same job but not like react. But in this new Reactjs version it will be more powerful and can complete redux where in cases it might beat redux in global state management.
Since ReactJs 19 still not introduced by React community officially so we can't validate these points now. But we hope that these above discussed points will make react more faster, robust, more poplular and more interesting from developers to IT companies.
