million VS solid-site

Hey HN! Founder of Million – We’re building a tool to that helps fix slow React code. Here is a quick demo: https://youtu.be/k-5jWgpRqlQ

Fixing web performance issues is hard. Every developer knows this experience: we insert console.log everywhere, catch some promising leads, but nothing happens before "time runs out." Eventually, the slow/buggy code never gets fixed, problems pile up on a backlog, and our end users are hurt.

We started Million to fix this. A VSCode extension that identifies slow code and suggests fixes (like ESLint, for performance!) The website is here: https://million.dev/blog/lint

I realized this was a problem when I tried to write an optimizing compiler for React in high school (src: https://github.com/aidenybai/million). It garnered a lot of interest (14K+ stars) and usage, but it didn't solve all user problems.

Traditionally, devtools either hinge on full static analysis OR runtime profiling. We found success in a mixture of the two with dynamic analysis. During compilation, we inject instrumentation where it's necessary. Here is an example:

  function App({ start }) {

To be honest, it fills me with great joy to finally be able to witness the launch of the 3.0.0 major release of Million.js; this is something that has been talked about since maybe July 2023, but, Aiden Bai finally assembled a team to get it out there and just last week on the day 2 February as at 8:00 am PST (Pacific Standard Time) Million v3 was released!!

Million.js is faster than preact, and lists a number of references under Acknowledgements: https://github.com/aidenybai/million#acknowledgments

> We use a novel approach to the virtual DOM called the block virtual DOM. You can read more on what the block virtual DOM is with Virtual DOM: Back in Block and how we make it happen in React with Behind the block().*

Consider replacing the default virtual DOM with an alternative solution. For instance, Million.js

In brief: I'm Aiden, 18, and have spent the past 2 years of high school working on Million.js, an open source React alternative with 11K stars on GitHub and hundreds of thousands of npm downloads.

Recently, I released automatic mode, which detects slow React components and automatically optimizes the reconciliation phase. It's still in beta but chugging along. It's around 70% faster than React on the JS Framework Benchmark and you can see how I did it here: https://million.dev/blog/virtual-dom

Either that or add signals to the library itself. I don't get why it isn't in there when a ton of React's competitors are either using signal-like behavior or forgoing the clearly-obsolete way React handles its VDOM. When a high schooler can create something to make the library faster, you know that the core team is either prioritizing the wrong things or someone managing React is too prideful to admit that a lot of what worked a decade ago doesn't work today.

SolidJS is a popular and open-source declarative JavaScript library that empowers reactive UI interfaces for the web that ensures a performant benchmark, leverages the flexibility of JSX and also provides support for TypeScript, Astro, and Vite.

In 2023 there are a wealth of developer options for front-end: React, Vue, Svelte, Solid and many more.

You may or may not yet have heard about Solid Start, which is the much anticipated upcoming meta framework for Solid.js currently being in beta.

SolidJS is a powerful, pragmatic and productive JavaScript library for building user interfaces with simple and performant reactivity. It stands on the shoulders of giants, particularly React and Knockout. If you've developed with React Functional Components and Hooks before, Solid will feel very natural because it follows the same philosophy as React, with unidirectional data flow, read/write segregation, and immutable interfaces.

Things like Solid (https://www.solidjs.com/) also have no virtual DOM, and the improves are in higher ceiling for performance, lower memory usage, simpler DX (components are not re-executed, there aren't any dependency arrays everywhere), easy high performance (no useRef this and useRef that to make things fast, no useCallback, no React.memo, these things are just obsolete).

Made with: - Windblade (my own version of Tailwind) - Solid JS - Vite

For the time being, this is how I approach web development on pretty much every project I have “architectural control” over. That’s how I worked with Solid.js and Tailwind CSS for the past 2 years. That’s how Vrite is being built. Has worked pretty well so far…
