   Socket – Secure your JavaScript supply chain▲133

   Excited to share the project I've been working on for the past 7 months! We've seen nearly weekly attacks against the open source software supply chain. I saw the seeds of this trend start in the mid 2015s as an open source maintainer and I've watched it only get worse over the years. I finally decided to try to solve this problem. Socket is taking an entirely new approach to one of the hardest problems in security in a stagnant part of the industry that has historically been obsessed with just reporting on known vulnerabilities. Unlike other scanning tools, Socket actually analyzes the…

    Mystral Native – Run JavaScript games natively with WebGPU (no browser)▲50

    Hi HN, I've been building Mystral Native — a lightweight native runtime that lets you write games in JavaScript/TypeScript using standard Web APIs (WebGPU, Canvas 2D, Web Audio, fetch) and run them as standalone desktop apps. Think "Electron for games" but without Chromium. Or a JS runtime like Node, Deno, or Bun but optimized for WebGPU (and bundling a window / event system using SDL3). Why: I originally started by starting a new game engine in WebGPU, and I loved the iteration loop of writing Typescript & instantly seeing the changes in the browser with hot reloading. After…

    Socket-call – Call socket.io events like normal JavaScript functions▲44

    Hello HN, I built a Typescript library (named socket-call, for lack of a more sexy name) whose goal is to be able to call socket.io events as regular functions. So you declare your server-side like so: ... const listenEvents = (services: UserServices) => ({ // Add your events here, the name of the event is the name of the function login: async (username: string) => { services._socket.data.user = { username }; console.log(`User ${username} logged in`); setInterval(() => { // Calling an event that's handled client-side services.showServerMessage(`You're still logged in…
