    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!
    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...
    

    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.

    Get your bitcoin on

    $ echo '{"op":"unconfirmed_sub"}' | wscat -k wss://ws.blockchain.info/inv
    

    The -k option is used to keep the socket open after the command has been sent, allowing us to read the continuous stream of Bitcoin transactions.

    Developing

    This node.js program is written in TypeScript and has a compile step that you can run with make lib. For developing it is convenient to install the ts-node and typescript modules globally (npm i -g ..), this will allow you to directly execute the programs entry-point: ./src/cli.ts.

    Use make test to run the tests and lint check and make lint to run the linter in formatter mode.
