Description

WebSocket Netcat with piping and subprotocol support.

Forked from jnordberg/wscat.

  

Installation

npm install -g wscat3

  

Examples

If you ever used nc, wscat works pretty much the same.

Connect to a server

$ wscat echo.websocket.org
Hello
Hello
Who's there?
Who's there?
^D

Chat

Server:

$ wscat -l 12345
Hi there!
Hi!
It's nice to speak to someone who just dosn't repeat everything I say back at me.
Yeah! Isn't it?!
Sorry, gotta run...
^D

Client:

$ wscat localhost:12345
Hi there!
Hi!

Transfer a file

Server:

$ wscat -b -l 12345 < ~/Desktop/mycat.jpg

Client:

$ wscat -b localhost:12345 > igotacat.jpg

Note that you can have the client send the file as well, after the connection has been setup wscat does not differentiate between server/client.
