    We've been building Crust (https://crustjs.com/), a TypeScript-first, Bun-native CLI framework with zero dependencies. It's been powering our core product internally for a while, and we're now open-sourcing it. The problem we kept running into: existing CLI frameworks in the JS ecosystem are either minimal arg parsers where you wire everything yourself, or heavyweight frameworks with large dependency trees and Node-era assumptions. We wanted something in between. What Crust does differently: - Full type inference from definitions — args and flags are inferred automatically. No…

    Hey HN, I'm 13, from Nigeria, and I just released PrinceJS — the fastest web framework for Bun right now. • 19,200 req&#x2F;s (beats Hono&#x2F;Elysia&#x2F;Express) • 2.8 kB gzipped • Tree-shakable (cache, AI, email, cron, SSE, queue, test, static...) • Zero deps. Zero config. Built in < 1 week. No team. Just me and Bun. Try it: `bun add princejs` GitHub: https:&#x2F;&#x2F;github.com&#x2F;MatthewTheCoder1218&#x2F;princejs Docs: https:&#x2F;&#x2F;princejs.vercel.app Brutal feedback welcome.

    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.

    I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input&#x2F;output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

    Hi HN, I’m sharing mochi.js (https:&#x2F;&#x2F;github.com&#x2F;0xchasercat&#x2F;mochi), a Bun-native, raw-CDP browser automation framework. It's designed to make programmatic browser use more effective by focusing on consistency and measured parity with regular traffic, purely from the JS layer, against stock Chromium. The most common forms of browser automation focus heavily on client-side line by line probes, which are mostly cosmetic. This makes people feel better but it doesn't have much relevance to actual WAF or anti-automation defences. Mochi.js focuses on what actually matters,…
