21st.dev▲1,211I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!

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…

Everyone's shipping AI tools right now, and here I am with a visual editor. Still, I think many teams are very familiar with the problem of "marketing wants to change the landing page again." I've run into this for years. Campaign pages come in, engineers get pulled in, and tickets stack up. It's usually the same components, just rearranged. A few years ago, at a startup I worked at, we built an internal tool to deal with this. You register your existing React components, they show up as drag-and-drop blocks, and the result is a JSX string. No schema to learn, no changes to your component…

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…
