24 alternatives to A JavaScript UI library for imperative JSX

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…

This JavaScript UI library offers an alternative to React's declarative approach by using imperative JSX, where JSX functions as a query interface for DOM manipulation rather than the source of truth for UI. Designed… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!

    I made this because building UIs in a lexical medium like code is super annoying. I have to pre-render what I’m making in my head, and then jump between the browser and IDE to test. I was inspired by the developer console in chrome and safari since I end up editing css there because it’s ironically more convenient. Hope it’s useful!

    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

    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…

    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…

    Hey HN, we built a Chrome Extension (https://www.magicpatterns.com/extension) that converts a snippet of any website to an isolated React component. Demo video: https://youtu.be/hutUYDkyE_A How it works: 1) Iterate through each node in the selected DOM tree, 2) For each element, find any matching CSS selectors / inline styles, 3) Use window.getComputedStyle to get the deterministic values, 4) Construct JSX It was pretty hard producing the minimal code necessary while maintaining the same visual look. To do this, we implemented things like abstracting out…

    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…

    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!

    Author here. This is an attempt to simplify frontend development: 1. Standards first: User interfaces should be assembled with HTML, styled with CSS, and enhanced with JavaScript. 2. Less abstractions: UI composition should be easy and require as few idioms and abstractions as possible, both on client and server. 3. Design Systems: Design should be a separate subsystem, easily accessible for developers who care about and understand design. 4. Scalability: Complex UIs should retain simplicity as the application grows. Eager to hear your thoughts!

    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…
