tcp-websocket-tunnel

Simple tunneling server between TCP and WebSocket.

About use node module:

• Listening for server start.
• You can stop server at any time.
• You can't get a connecting sockets.

Install

For using on shell:

npm install -g tcp-websocket-tunnel

For use node module:

npm install tcp-websocket-tunnel

Listen on TCP server Port 25565, destination to ws://localhost:8080

Shell:

tcp-websocket-tunnel --from 25565 --tows ws://localhost:8080

Node module:

const { toWebSocket } = require('tcp-websocket-tunnel')

const server = toWebSocket(25565, 'ws://localhost:8080')
server.on('listening', () => {
    console.log('listening')

    // Any code

    server.close()
})

Listen on WebSocket server Port 8080, destination to TCP localhost:25565

Shell:

tcp-websocket-tunnel --from 8080 --toport 25565 --tohost localhost

Node module:

const { toTCP } = require('tcp-websocket-tunnel')

const wss = toTCP(8080, 25565, 'localhost')
console.log('listening')

// Any code

wss.close()

Node module (Use in express-ws):

const express = require('express')
const app = express()
const expressWs = require('express-ws')(app)
const { toTCPOnConnection } = require('tcp-websocket-tunnel')

app.ws('/ws', (ws, req) => toTCPOnConnection(ws, 25565, 'localhost'))

app.listen(process.env.PORT || 3000)

Node module (Use in @fastify/websocket):

const fastify = require('fastify')()
fastify.register(require('@fastify/websocket'))
const { toTCPOnConnection } = require('tcp-websocket-tunnel')

fastify.register(async (fastify) => {
  fastify.get('/ws', { websocket: true }, (connection, req) => {
    toTCPOnConnection(connection.socket, 25565, 'localhost')
  })
})

const start = async () => {
  try {
    await fastify.listen(process.env.PORT || 3000, '0.0.0.0')
  } catch (err) {
    fastify.log.error(err)
    process.exit(1)
  }
}
start()
