In the maker’s words, at launch

WHat if you could take Node.js event emitter and turn it into a distributed pub-sub system? I built Demitter to solve a problem I kept thinking about recently: how to easily share events between Node.js processes without the complexity of setting up Redis, RabbitMQ, or other heavyweight message brokers? It uses…

  Simple pub/sub using WebSockets in Node.js2022 · npmjs.com · ▲13

  I built this pubsub module because I wanted a simple solution that uses only node. Why did I want pubsub? I wanted to build a complex app but segregate it into microservices that work together through event messages. I also wanted to use this method instead of node's built-in clustering for multiple instances. I've been running it for a few weeks now with several messages per second bugfree. I plan to use this setup for future apps as it reduces complexity of the code and allows me to restart/update one part of the app without interrupting the other parts. I would love to receive…

  Nub – A Bun-like all-in-one toolkit for Node.jsJun 2026 · github.com · ▲277

  Colin here, creator of Nub. I’ve had the general shape of this in mind for years. Nub runs your code with stock `node`, augmented with a `--require` preload hook[0] that adds a transpiler (oxc-powered, packaged as a Node-API add-on), registers a module resolution hook[1], and injects polyfills as needed for APIs like `Worker`, `Temporal`, etc. All purely additive, your code ultimately runs using Node’s actual engine & stdlib implementations.

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Trickle - Magic Canvas ▲1,064

  Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better? Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game. 1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

  Ten years of running every day, visualized▲958

  Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

  Draw a fish and watch it swim with the others▲935

  Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https:&#x2F;&#x2F;www.morningbrew.com&#x2F;issues&#x2F;business-buzzkill), MetaFilter (https:&#x2F;&#x2F;www.metafilter.com&#x2F;209703&#x2F;Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…

  Use Their ID – Use your local UK MP’s ID for the Online Safety Act▲862

  Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
