24 alternatives to I built a JavaScript UI library with reactive atomic updates
Hey everyone! Some time ago I was analyzing why React apps are so hard to optimize, and came to a conclusion that the lack of atomic updates is the culprit. I made an experimental library which basically updates everything in place directly in HTML. At some point I became aware that Solidjs exists, which is a very similar idea, but at the end of the day I realized my approach to API is quite different and warrants the existence of my library (my state primitive allows selector subscriptions, array iterators return a state primitive with the element, allowing to never re-render the whole…
Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. I built a JavaScript UI library with reactive atomic updates launched in 2024; newer entries below may have overtaken it.

Hi! I made a React compatibility library for a Virtual DOM library (https://github.com/aidenybai/million). The idea is to have much faster rendering (a compiler optimizes virtual DOM beforehand) while ensuring the same developer experience React provides. This is very, VERY early stage, so be prepared for weird bugs / plugin incompatibility / etc. If you have any suggestions, I'd be more than happy if you replied in a comment with it! You can spin up the demo here >> https://stackblitz.com/github/aidenybai/million-react-compat

I've been building a web UI library for a side project of mine. I thought it might be useful to others, so I'm releasing it as open source. To put it simply, I realized that most of my pain points with React come from its declarative model ui=f(state). So I'm trying something that I'm calling "imperative JSX." Instead of treating JSX as the source of truth for your UI, it essentially becomes a query interface for DOM manipulation. I first had the idea for it a few months ago, and only began writing it in earnest last week, so it's extremely early and nowhere near production-ready. Still, I'd…

Yes, another reactive UI framework for JavaScript. Bear with me, please... :-) I 'invented' the concept for this back in 2011, and it was used (as a proprietary lib) in various startups. Even though many similar open source libs have been released since, and boy have I tried a lot of them, none have been able to capture the elegance and DX of what we had back then. I might be biased though. :-) So I started creating a cleaned-up, modern, TypeScript, open source implementation for the concept about five years ago. After many iterations, working on the project on and off, I'm finally happy…

Looking at websites such as Clerk, I began thinking that design engineers might be some kind of wizards. I wanted to understand how they do it, so I started reverse-engineering their components out of curiosity. One thing led to another, and I ended up building a small library of reusable, animated components based on what I found. The library is built in React and Framer Motion. I’d love to hear your feedback

Hi HN! I created this lib in the need of a simple and tiny framework to easily do AJAX-style navigation / replacement of fragments in the page, in a web application. For people who don't want to use client-side-rendering and complex frameworks à la React, there are nowadays a few "HTML-over-the-wire" libraries, like HTMX, Unpoly or this super-tiny one Swap.js :) One other key thing is that no external tool is needed: no bundler, no webpack, no TypeScript compiler, no minification needed. Just write HTML, JS (+ your preferred server-side language: PHP, Python, etc.) and it works. The…

Hi Everyone! My main motivation for making this was that I wanted something as powerful as Svelte or React but I wanted no build steps, no JSON API, and I wanted something as close to vanilla js as much as possible. I'm mainly a backend developer, and I wanted to simply return html with some interactive islands when I need to (whose components get 'hydrated' with by backend language's templates). Some key ideas: • It's centered around light dom web components • Uses a "reactive element", which uses observables for fine-grained reactivity • Rendering is done through lit-html's tagged…

Hi all, I'm currently working on my hobby project, and one of the fun constraints I put in was to build using as less dependencies as possible. I chose Go as it has a really good standard library, and all went well for building backend. But for frontend, I was wondering whether I should break the constraint and go for React. I tried options like Web Components, but I really didn't like the ergonomics and I didn't want to use jQuery either. Out of curiosity, I was exploring Go's html/template package to see if I can write UIs in a React-like manner. I found most of the online docs using…

Hi everyone, I've been working on this thing for a while. It transpiles Haml into Ruby, and then it streams patches to the browser which update the DOM. There is a memory leak in s.rb, which I'm not really sure how to solve. Seems like objects stay alive for longer than they should because of circular references or something but I'm not sure what's going on to be honest. I think this approach has potential though.

with affinity you can make multiple apps (components eventually) and store (ala redux) - while a store can be shared through apps. This started as a case study and as a small reusable code for creating self contained dom elements with functionality - during the time of development, ideas and inspiration came from angular, react and vuejs. suggestions and feedback is mostly welcomed. The interesting challenges were finding ways for these topics: 1. create a component lib using dom and js only, without any 3rd party . 2. producing semantic html in dom . 3. allow template micro syntax (using…

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 Interested? Check it out here: https://million.dev

LemonadeJS▲21Hey HN, We just released v5 of LemonadeJS, a micro-reactive library (~5.5KB compressed, no dependencies) that brings reactivity, scoped state, and JSX support to browser-native JavaScript. Key Features in v5: - Private reactive state for components - Scoped events for modularity - JSX support (via a Babel plugin) - children argument for nested components - Template literal interpolation - Improved DOM rendering performance Use it with plain JS, TypeScript, or JSX — no build step required. Ideal for browser tools, widgets, or building fast UIs without bundlers.…

Hello everyone, For the past several months, I have been building multiple React/TailwindCSS components for my projects. I have decided to bundle and document them so that I can share them with the community. The entire UI kit is written in Typescript on top of the class-variance-authority library. Although I am already using these components in production, the project is still in beta since it lacks a full test suite and dark mode. Please feel free to take a look and provide feedback if you have a moment to spare. Thank you!
