node-websockify (inspired by @maximegris/node-websockify)

WebSocket-to-TCP proxy/bridge in NodeJS

If you want to run a websockets to tcp proxy alongside a standard http server, this package is for you.

It is very similar to the aformentioned @maximegris/node-websockify, but the big difference is that library spins up a standalone web server. If you are already using a http server, you would be out of luck. This package lets you do that!

This has not been tested at all for any use cases aside from what Simplemnt uses. PRs and issues welcome.

Probably works on Node 10+ only, but may work all the way back to Node 6.

Installation

npm install --save @simplemnt/node-websockify

Usage

const websockify = require('@simplemnt/node-websockify')
const wsProxy = websockify('HOST:PORT')
 ...
 ...
 wsProxy(httpServer, 'path-to-serve-websockets-on')

Express

const express = require('express')
const app = express()
const server = require('http').Server(app)

const port = process.env.PORT || 8080

const websockify = require('@simplemnt/node-websockify')
const wsProxy = websockify('0.0.0.0:5900')

server.listen(port, () =>  console.log('listening on *:' + port))
wsProxy(server, '/some-path')

http (untested)

const http = require('http')

const port = process.env.PORT || 8080

const websockify = require('@simplemnt/node-websockify')
const wsProxy = websockify('0.0.0.0:5900')

const server = http.createServer()
server.listen(port)
wsProxy(server, '/some-path')
