24 alternatives to Classix – The fastest and tiniest utility for joining classNames

classix is a npm package for joining classNames, typically used with React. It is much smaller and faster than alternative libraries: clsx and classnames. Comparison: https://github.com/alexnault/classix#comparison What's more, classix only accepts string expressions as argument (no objects). This simplification of the API enforces a single and consistent way of joining classNames, for teams and solo developers.

    Swap.js – a JavaScript micro-framework (HTML fragments over the wire)▲127

    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…

    A JavaScript UI library for imperative JSX▲41

    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…

    Functional UI Kit – twin Figma and React component libraries▲101

    Hey Hackers! My name is Alex and I’ve been working on this project for the past 8 months with the support of Figma Creator Fund. I’d love to hear your thoughts from your experience working with designers & component libraries. I started out in design and later got into coding, so I understand both sides really well. I did UX Design for 12 years at startups, at my own studio and at Wix, and then worked as a front-end dev at Wix for 2 more years. I've noticed a common problem: most component libraries work great for devs but not so well for designers. In my experience working with big teams,…

    CodeCafé – A real-time collaborative code editor in the browser▲81

    Hey guys! I’ve been working on a web app called CodeCafé—a collaborative, browser-based code editor inspired by VS Code and Replit, but with no downloads, no sign-up, and zero setup. You just open the link and start coding—together. The frontend is built with React and TypeScript, and the backend runs on Java with Spring Boot, which handles real-time editing via WebSockets. For syncing changes, I’m using Redis along with a custom Operational Transformation system (no third-party libraries!!!). The idea came after I found out a local summer school was teaching coding using Google Docs (yes,…
