ProppyJS: JavaScript library for functional composition of props for UI components
Your component layer ends up becoming stateless, and only responsible for accepting props and rendering them. Integrating other libraries to your components layer becomes a breeze with the suite of functions that Proppy provides you. With your props being composed in functions, they become easier to expand as your requirements grow. With clear separation between props generation and components, you can now unit test them separately with ease. With Proppy's providers, you can set application-wide global object accessible anywhere in your components tree. Since Proppy connects to your favourite UI rendering library, you have the freedom to switch with minimalfrom proppyjs.com

- IMI made React with a faster Virtual DOM2022 · ▲109
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

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
