tinyws

tinyws is a WebSocket middleware for Node.js based on ws, inspired by koa-easy-ws. Check out chat example to get familiar with tinyws.

Features

• Small size (498B)
• Easy to use (only req.ws and nothing else)
• Framework-agnostic (works with tinyhttp, express etc)
• Written in TypeScript

Why not express-ws?

because express-ws is...

• Abandoned since 2018 💀
• Doesn't come with types out of the box (have to install @types/express-ws)
• Not compatible with tinyhttp and polka
• Buggy as hell
• Doesn't have tests

Install

pnpm i ws tinyws

Example

import { App, Request } from '@tinyhttp/app'
import { tinyws, TinyWSRequest } from 'tinyws'

const app = new App<any, Request & TinyWSRequest>()

app.use(tinyws())

app.use('/ws', async (req, res) => {
  if (req.ws) {
    const ws = await req.ws()

    return ws.send('hello there')
  } else {
    res.send('Hello from HTTP!')
  }
})

app.listen(3000)
