   DriftDB – an open source WebSocket backend for real-time apps▲367

   Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…

   Firefox in WebAssembly▲273

   This is the entire Firefox browser rendering to a element. Gecko, all UI components, and the Spidermonkey JS engine are all compiled and running in WebAssembly. Here are a few things you might find interesting: - This is fully end to end encrypted! We use the WISP protocol for TCP-over-websockets. - There is a novel WASM->JS JIT for experimental site speedup - This port cost over 25k in opus/fable tokens for debugging and JIT research This was just a fun experiment to push the boundaries of WebAssembly. For a more usable "browser in browser" experience, we also built…

   Common Lisp running natively over WebAssembly for the first time▲97

   A month or so ago, I ported a Common Lisp implementation (npt) to WebAssembly to make a silly blog post, because I was bored and have a lot of time on my hands to waste with things like this (I don't have a job, and because I have next to no experience, these meaningless, silly projects tend to fill what time I do have). This is significant as it's the first time Common Lisp in particular has ever been hosted on it; wasm has a few poor decisions in its design that make it less-than-conducive to being a target for Common Lisp, and a lot of the more interesting implementations require an…

    WAPM – WebAssembly Package Manager▲186

    Hi HN! I’m Syrus, from the Wasmer team. We just released the new version of WAPM that is an order of magnitude better than the previous one (that we also announced here in HN two years ago! [0]), enabling an incredible experience for using and publishing WebAssembly packages. The tech stack that we are using includes: * Python and Django (for the backend) with Graphene (for the open GraphQL API [1]) and Django Channels with websockets over GraphQL [2] for subscriptions * Next.js [3] with React-Relay [4] and Tailwind.css [5] for the frontend * WebAssembly and Wasmer [6] (for the online shell)…

    Hocuspocus 4 – self-hosted Yjs collaboration backend▲38

    Hi HN! I'm Philip, one of the founders of Tiptap. Next to our open-source rich text editor framework, we started developing Hocuspocus about five years ago and open-sourced it too, to solve one of our biggest challenges back then: real-time collaboration in web editors. We found Yjs by Kevin Jahns, a CRDT library that handles concurrent edits without conflicts. Basically, Yjs merges changes from users without conflicts and in real-time. Hocuspocus is the WebSocket server built on top of Yjs. It handles real-time sync, presence/awareness, persistence, and Redis-based scaling. While we…
