Hey devs, I got tired of ws + isomorphic-ws + cross-fetch + polyfills just to open a socket that works everywhere.
So I wrote @rabbx/ws: a 9KB WebSocket client/server that runs on Node, Bun, Deno, and Cloudflare Workers with the same code. Zero dependencies. Web standard APIs only.
Why:
9KB vs 1.2MB - ws pulls 14 deps. socket.io-client is 85KB gzipped. This is 9KB total.
Zero deps - No debug, no safe-buffer, no ultron. Just EventTarget and WebSocket.
Same code everywhere - new RbxSocket(url) works in Node 20, Bun, Deno, Workers. No if (isBrowser) branches.
Cold starts matter - On Cloudflare Workers, importing ws costs 120ms. This costs 8ms. That’s the difference between 50ms and 170ms TTFB.
