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…

I made this because building React components from scratch is super annoying. Most visual elements already exist on the web, and I figured there should be a way to leverage that. I 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

Hi HN, I got to work yesterday and today and came up with a very simple way to create and manage state in TinyJS. I end up creating a simple App to illustrate how to use the new createState function and custom components in a React like manner. Here's the code for it - https://github.com/victorqribeiro/tinyapp Here's the PR for the createState function - https://github.com/victorqribeiro/TinyJS/pull/9

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…

Hi all, author here. This project was a pleasure to do, Remix has very good developer experience. But further than that it's actually a really good way to develop applications, it's a mix of old meets new where the paradigm encourages you to take advantage of web standards for data fetching (forms, links, a tags). And it turns out that it's actually an optimal way to develop simple or even complex web applications which can deploy in a number of runtime environments (including edge workers). So you can get an insanely fast website for users. Note that this project is not necessarily an…

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
