24 alternatives to Aberdeen – An elegant approach to reactive UIs
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…
Aberdeen is a reactive UI framework for JavaScript built with TypeScript that automatically updates DOM elements when underlying data changes. It uses small anonymous functions to emit elements and proxied data objects… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Fir leverages Golang’s standard library html/template package and a bit of alpinejs to allow building reactive UIs. You start with plain old html and use alpinejs to enhance it to bring no-page-reload interactivity to web apps. The Fir toolkit is designed for Go developers with moderate html/css & js skills who want to progressively build reactive web apps without mastering complex web frameworks. It includes a Go library and an Alpine.js plugin. How it works ? On receiving user-interactions the fir server re-renders html templates and sends it over the wire where the fir client…

We've been building Crust (https://crustjs.com/), a TypeScript-first, Bun-native CLI framework with zero dependencies. It's been powering our core product internally for a while, and we're now open-sourcing it. The problem we kept running into: existing CLI frameworks in the JS ecosystem are either minimal arg parsers where you wire everything yourself, or heavyweight frameworks with large dependency trees and Node-era assumptions. We wanted something in between. What Crust does differently: - Full type inference from definitions — args and flags are inferred automatically. No…

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…

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 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…

For a year or two I've been building a UI library with the aim of making desktop applications fun and easy to write. It is currently written in C/Ruby and uses a custom tree sitter grammar to describe templates. Features include: composable UI components, template directives, event and prop handling, slots, styles and automation capabilities baked in. One of the goals of the project is privileging easy to write custom components via a drawing API over providing a fixed set of components. At the time of this writing it should install on Windows, Mac, and Linux, but sometimes it is hard…

RedwoodJS▲203Hey everyone, I'm the original co-creator of RedwoodJS. (The framework that myself and Tom Preston-Werner, Rob Cameron and David Price built during Covid.) I had tried to build a developer tool startup (Snaplet), and failed. I rejoined the efforts to add RSC to Redwood, but I realized that we needed a much simpler framework that was closely tied to a platform (We chose Cloudflare). We started building RedwoodSDK a year ago and this is the result. An insanely simple stack. I am incredibly proud of this work, please star our repo and let me know if there's anything that doesn't resonate with…

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…

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…
