with affinity you can make multiple apps (components eventually) and store (ala redux) - while a store can be shared through apps. This started as a case study and as a small reusable code for creating self contained dom elements with functionality - during the time of development, ideas and inspiration came from angular, react and vuejs. suggestions and feedback is mostly welcomed. The interesting challenges were finding ways for these topics: 1. create a component lib using dom and js only, without any 3rd party . 2. producing semantic html in dom . 3. allow template micro syntax (using…

I wanted to have a framework that would let me build web apps faster than ever before. I didn’t care if it was a little hacky or didn’t use best practices — I wanted to be able to get a multi-user application out the door in hours instead of months. I researched the CMS space for months before deciding to build something from scratch. My goal was to be 90% done building a web app once I had the static HTML and CSS finished. I’m not a big fan of building out API endpoints over and over again for every new app, fiddling with a database, or doing lots of config. What I ended up with was a…

Hi everyone, After four years, I'm finally open sourcing my little markup language that compiles directly to HTML, and has all the "modern" features built into the core, (reactive components, server side rendering, modules, bundling, etc.). No metaframework required! Feels like I really have something here, I'd love your feedback :)

Raw performance (the lack of) is always a contentious point for JavaScript, especially in our post-Moore era of computing. Node.js gets around this issue through extensive of use of native libraries and modules written in C, including the V8 JS engine itself. But as application developers, how do YOU create high performance functions? Write in C and run as a NAPI module? Write in Rust and run as a V8 wasm? Well, there is another (better and faster) way now! The SSVM is a fully featured WebAssembly VM that is optimized for server-side applications.…

Hey everyone! Some time ago I was analyzing why React apps are so hard to optimize, and came to a conclusion that the lack of atomic updates is the culprit. I made an experimental library which basically updates everything in place directly in HTML. At some point I became aware that Solidjs exists, which is a very similar idea, but at the end of the day I realized my approach to API is quite different and warrants the existence of my library (my state primitive allows selector subscriptions, array iterators return a state primitive with the element, allowing to never re-render the whole…

Hi everyone, I've been working on this thing for a while. It transpiles Haml into Ruby, and then it streams patches to the browser which update the DOM. There is a memory leak in s.rb, which I'm not really sure how to solve. Seems like objects stay alive for longer than they should because of circular references or something but I'm not sure what's going on to be honest. I think this approach has potential though.

Hi HN, Added a raw 45-second demo showing the DOM re-architecture in real-time: https://streamable.com/vw133i I got tired of the "Context Problem" with static portfolios—Recruiters want a resume, Founders want a pitch deck, and Engineers want to see architecture. Instead of building three sites, I hooked up my React frontend to Llama-3 (via Groq for <100ms latency). It analyzes natural language intent from the search bar and physically re-architects the Component Tree to prioritize the most relevant modules using Framer Motion. The hardest part was stabilizing the Cumulative…

Hey HN! I think _hyperscript is an insanely cool language, and while designed for simple front-end DOM interactions, I thought it would be a cool back-end scripting language as well. So, I slapped together a TODO app with a _hyperscript bootstrapping script based on the original repository's node-hyperscript example. My repo isn't clean, just something I worked out over a weekend to prove the concept, also an excuse to play with htmx. :) Please read the README, and let me know how, if anyone's interested, I can work in some of my tweaks to the original repository. I'm kind of a noob with…

Hi HN, For the last ~15 years I've worked on embedding web browsers into Java and .NET desktop apps (JxBrowser, DotNetBrowser). Over time, I watched many teams move from embedding web views into native apps, to building full desktop apps with frameworks like Electron and Tauri. Both are useful, but in practice I kept running into several problems. With Electron, beyond the larger app footprint, I often ran into: - lack of type-safe IPC - no source code protection - weak support for the modern web stack Tauri solves some problems (like app size), but introduces others: - different WebViews…

Happy New Year HN! I’m the co-creator of Orbiter, a dead simple tool for uploading and hosting static sites. We built Orbiter for ourselves and realized it would probably be useful for others. Static site content is some of the simplest on the web, yet hosting this content has gotten increasingly complex over time. Many of you are engineers and don’t have much problem with CI/CD pipelines as a mechanism for deploying a website. This is true for me as well. But there are times when I want to just upload a simple website. I might not even want to put it under source control. And I know…

Hello HN, I had some christmas free time over the last two weeks (Merry Christmas btw ;-)) and used that time to completely recreate the website of my app[1]. I used all the fancy new tools. I didn't know some of them when I started. What was my goal? * Pretty website * Blazing fast * Mobile first * SSR * Webp support * Generally all the best website practices (high lighthouse score) What did I use? * Tailwindcss (https://tailwindcss.com/) * Tailwind Components (https://tailwindui.com/) * React (https://reactjs.org/) * ViteJs…

live-paint (https://paint.liveviews.cc/) is a demonstration of ts-liveview v2-rc3. The server converts JSX expression into plain HTML response. The UI is then updated via websocket. As opposite to React.js. The DOM updates are fired from server, and instructed with query selector (no virtual DOM). Hence, the amount of javascript downloaded and executed by client are minimal (or even optional for static web pages).

Hey Everyone, I just ran a [rather silly] race between Puppeteer (JS), Playwright (Python) and Selenium (Python) to see which one would be fastest on a simple scrape (using Google Colab so you can also run it) Far from a comprehensive benchmark, this race is 100% free from advanced configurations, multi-threading or anything complicated. It just opens Wallapop (a second hand marketplace in Spain) and times how long it takes to extract the first 2000 results of a search. If you like this simple format, have any ideas on how to improve a race like this or have a strong urge to prove Ward…

I’ve spent the last few days prototyping a browser-based game engine stack designed for instant-load, "Roblox-for-Teens" style deployment. The goal is to lower the floor for AA indie devs who want high-fidelity physics and instant web distribution without the overhead of Unity or a heavy Godot export. The Stack Engine: A headless WASM/WebGPU implementation. I’m currently using custom flags and selective streaming to bypass standard browser memory and execution limits. Physics: I’ve ported Jolt (Guerrilla Games) but modified the solver to mimic the original Blam! engine (Bungie/Halo…
