    Hello HN, I'm releasing Hyperdiv (https://hyperdiv.io), a framework for rapidly developing reactive browser UIs in Python, with immediate-mode syntax and using Shoelace (https://shoelace.style) as its built-in component system. This short coding video will give you a good idea of what it is: https://www.youtube.com/watch?v=4XJKfxaqvGE I wrote a brief article about the motivation and approach: https://hyperdiv.io/intro.html Hyperdiv doesn't aim to compete with serious full-stack frameworks. The core aim was to make it easy and fast to…

    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…

    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…
