Simple shell scripting APIs for spawning a TCP server. This is basically a high-level wrapper around socat.


Launch a "Hello World" TCP server:

#!/usr/bin/env import
import tcp@0.0.2

tcp_server echo hello world
Run this code

And interact with it using netcat, or telnet:

$ netcat localhost 3000
hello world


tcp_server $command

  • port - Optional port number to bind to. Defaults to 3000.

Spawns a TCP server that executes the given command upon every connection to the server. The server binds to the port using the reuseaddr flag.

#!/usr/bin/env import
import tcp@0.0.2

# Imagine that `` implements the Redis RESP protocol
port=6379 tcp_server ./
Run this code
