# wsmux - a simple WebSocket tunnel server

Start an HTTP server that accepts incoming WebSocket connections and bidirectionally forwards data between the established connection and a TCP destination reachable from the server.

Define the destination address at runtime with an elegant protocol:

```

ws:///tunnels/${base64(':')}'

```

The primary goal of this project is to provide a handy library.

The `wsmux` binary was added for demonstration purposes (but can potentially be used as a standalone tool as well).

Usage:

```sh

# Server - listen for incoming WebSocket connections and tunnel ports

wsmux serve [-addr [host]:]

# Client - forward local port to remote destination via wsmux server

wsmux proxy -server  -local-port  [-local-host ] -remote-port  [-remote-host ]

```

Example:

```sh

# On the server, prepare the targets (e.g., nginx & httpbin)

$ docker run --rm -p 127.0.0.1:3000:80 nginx:alpine

$ docker run --rm -p 127.0.0.1:5000:80 kennethreitz/httpbin

# On the server again, start the wsmux server

$ wsmux serve -addr 0.0.0.0:8080

Starting wsmux server on 0.0.0.0:8080

# On the client, start the wsmux clients to forward local ports to the targets

$ wsmux proxy -server ws://0.0.0.0:8080 -local-port 3001 -remote-port 3000

Starting wsmux client on localhost:3001 -> localhost:3000 via ws://0.0.0.0:8080

$ wsmux proxy -server ws://0.0.0.0:8080 -local-port 5001 -remote-port 5000

Starting wsmux client on localhost:5001 -> localhost:5000 via ws://0.0.0.0:8080

# Now, you can access the nginx server on http://localhost:3001

$ curl http://localhost:3001

Welcome to nginx!

...

# ...and httpbin on http://localhost:5001

$ curl localhost:5001

    

    httpbin.org

...

```
