    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…

    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…

    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…
