react-native-web VS webpack

maybe https://necolas.github.io/react-native-web/? https://github.com/vercel/next.js/blob/canary/examples/with-react-native-web/README.md

I am following a tutorial that is 4 years old that states that react native 0.55.4 is last compatible with react native web and anything later is not compatible yet. He showed the documentation page in the video as his source.

Personally, if you're trying to find a stack that can be applied everywhere with Next.js as your chosen framework, best bet would be React Native Web or similar. Which would let you share the maximum amount of frontend code between Web, iOS, and Android. Then you could reach for electron (barf) or something to bundle it for desktop if that was a requirement.

Some of the top cross-platform frameworks do have support for web targets. React-Native-Web and Flutter on the Web are both ways to target the web with your cross-platform app.

https://github.com/necolas/react-native-web/discussions/2201 it can be done.

If you want a single codebase for web and mobile I would look into react-native and react-native-web. You could probably code the web app with react-native-web, make it responsive and build it through react-native for mobile. Designing an app for mobile and for web can lead to significant difference though since the experience is quite different. Some things might make sense for a mobile and not for a desktop or the opposite. So I wouldn't discard completely the idea of having separate codebases. Highly depends on the app though, totally valid for many use cases.

Another fun thing you could do is build it for mobile + web using React-Native through Expo or manually with https://necolas.github.io/react-native-web/

If you're using Expo (which I assume most are on RN) they have web support. This is via React Native Web, which is a separate project if you wanted to use that directly too.

Personally though, I've found the DX of Flutter far above RN. I always had random packages break on RN that I had to fix every time, while with Flutter most of what you need is already included in the framework, including a component UI library for Android and iOS.

So the RN-R part is done by https://necolas.github.io/react-native-web/ and it's really good! However, there are some code that is kind of outside of the scope of React. Ie. Navigation, that's more in the realm of Next.

I don't have personal experience with this, but React Native Web claims to solve this issue: https://necolas.github.io/react-native-web/, not sure if anyone has had experience with this. Of course, you will have issues with dependency hell/package maintenance.

Another great option seems to be Flutter web. I was really impressed by the "batteries included" approach to Flutter, and Dart has a pretty comprehensive standard library. This is in contrast to React's "just find a random package on npm and pray it doesn't bite you in the future."

Obviously rewrites are expensive, but I personally think both approaches are worth considering versus abandoning native components completely. WebView isn't without problems (and also, you don't need React Native to use WebView).

Click "Start Test." WebPageTest generates a comprehensive report with details about the loading process, including time to first byte (TTFB), page load time, and visual progress. ### Setting Benchmarks with Lighthouse Start with Lighthouse audits to maximize the performance of your React application. Evaluate Lighthouse's scores and suggestions with careful consideration. Next, set benchmarks that are in line with industry norms or customized to meet your unique performance goals. Lastly, pay close attention to the places in your application where it needs work. You can improve your React application's effectiveness by carefully following these procedures, which will guarantee that it satisfies the required performance requirements. ### Analyzing Performance Results with WebPageTest In order to fully evaluate your webpage's performance, launch WebPageTest with a variety of systems, simulating a variety of user scenarios. Examine the waterfall chart carefully to identify loading patterns and bottlenecks, which are essential for improving the user experience. To see the page's rendering process over time and do a thorough examination, use filmstrip views. To effectively assess performance, pay special attention to measures such as time to first byte (TTFB), start render time, and fully loaded time. Also, a better understanding of performance variances is made possible by comparing findings across various test designs, which helps make well-informed recommendations for improving webpage responsiveness and efficiency. ## Impact of third-party libraries on React app performance Third-party library integration can speed up development while improving functionality in our React application. It's crucial to consider the possible effects on performance, though. Because heavy or poorly optimized libraries might negatively impact the speed and usability of our application. ### Bundle Size Look at the distribution file sizes related to the library, and use tools such as Bundlephobia or Webpack Bundle Analyzer to fully evaluate their impact on your bundle size. This thorough analysis enables you to make well-informed decisions about whether to include the library, making sure that its contribution minimizes superfluous bulk in your application's codebase and is in line with your optimization goals. ### Network Requests Analyze how the third-party library affects network requests to maximize performance. Reduce the number of requests made overall by minimizing external dependencies. This will enhance the user experience and loading speeds. Select appropriate libraries, maximize asset delivery, and leverage code splitting to load components asynchronously. You may improve the effectiveness and responsiveness of your application and provide users with a better experience by cutting down on pointless network queries. ### Execution Time Examine the library's code for any possible performance problems or bottlenecks in order to analyze the runtime performance of the library. Look for places where the code may execute slowly or inefficiently. You may ensure smoother operation inside your application by identifying and addressing any areas of the library's implementation that may be impeding ideal performance by doing a comprehensive assessment. ### Code Splitting for Third-Party Libraries Implementing code splitting is an effective strategy to load third-party libraries only when they are required, reducing the initial page load time. Use dynamic imports to load the library lazily:

Thanks for the thorough answer!

I confess I wasn't thinking about a particular build tool. My recent experience has been with Vite, where I took a similar approach to what you describe, but haven't had to dig deep into bundle performance because that's not a bottleneck for our application. The last time I did deeper work on the subject was years ago with Webpack.

I thought Webpack at least did dead-code elimination before splitting things into chunks. If I'm reading this random GitHub issue[1] right (and the asker is also right), Webpack does partially behave as I expected, but the pre-chunking optimization pass occurs before things like constant expression evaluation.

Webpack is a powerful and widely-used module bundler for JavaScript applications. It’s known for its flexibility and extensive plugin system, making it a popular tool in complex web development projects.

Thats all about Webpack Basic, there are lots of feature of webpack, You can check here: https://webpack.js.org/

Many web pages use CSS and JavaScript files to handle various features and styles. Each file, however, requires a separate HTTP request, which can slow down page loading. Concatenation comes into play here. It involves combining multiple CSS or JavaScript files into a single file. As a result, pages load faster, reducing the time spent requesting individual files. Gulp, Grunt, and Webpack are some of the tools that can assist you in speeding up the concatenation process. They enable seamless merging of many files during development, ensuring deployment readiness.

Once you build a simple Vite backend integration, try not to complicate Vite's configuration unless you absolutely must. Vite has become one of the most popular bundlers in the frontend space, but it wasn't the first and it certainly won't be the last. In my 7 years of building for the web, I've used Grunt, Gulp, Webpack, esbuild, and Parcel. Snowpack and Rome came-and-went before I ever had a chance to try them. Bun is vying for the spot of The New Hotness in bundling, Rome has been forked into Biome, and Vercel is building a Rust-based Webpack alternative.

Webpack is a module bundler, the main purpose of which is to bundle JavaScript files to make them usable in a browser.

NPM packages include a wide range of tools such as frameworks like Express or React, libraries like jQuery, and task runners such as Gulp, and Webpack.
