million VS Alpine.js

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!!

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.

Alpine.js for reactive frontend

✨ In recent months, I have been developing web projects using GOTTHA stack: Go + Templ + Tailwind CSS + htmx + Alpine.js. As soon as I'm ready to talk about all the subtleties and pitfalls, I'll post it on my social networks.

> But honestly, torn towards htmx but undecided.

We are in the middle of migrating from our monster react application into server rendered pages (with jinja2). The velocity at which we are able to ship and the reduction of complexity has been great so far.

Managing client side state for simple things like (is the dropdown open/closed), listening to keyboard events and such can be done with something like alpine-js [1] without all the baggage that something like react brings.

It appears this is already the trend with JS frameworks too - with server side rendering being the new norm.

Sure, you can use any number of JS-avoidance libraries. I'm a fan of Turbo, and there's also htmx, Unpoly, Alpine, hyperscript, swup, barba.js, and probably others.

Direct DOM, but with a library. Specifically AlpineJS since it follows Vue closely in design practices allowing me to scale into a full web application if necessary (basically swapping to Vue takes minimal work). The Morph plugin is specifically what I like using.

If you want more details on the initial setup I encourage you to take a look at the Part I that covers more of the initial implementation. For this portion, I added Prisma as an ORM, a frontend style library called Tachyons, and AlpineJS to handle any client-side interactions. I did this to avoid needing to add a client-side bundler to the build and instead just rely on plain old module imports to compose the frontend. This is now the default for Rails and it is quite nice to not need any additional build tools for the client.

If you’ve followed our other tutorials, you might be familiar with Alpine.js. It’s a lightweight JavaScript library that allows you to add interactivity to your site without writing a single line of JavaScript. It’s incredibly easy to use, and we’ll show you how to make the animation trigger when the user scrolls to it.

The approach is not new, essentially a variation of Knockout, Alpine, and similar "JS-in-HTML" approaches.
