WebSocket Subprotocol

[ArtiomL]

Hi,

Some WebSocket servers require specifying the subprotocol value used in the Sec-WebSocket-Protocol header during the handshake.

I have added a new argument (-s, --subprotocol) that updates the connection protocol option.

Thank you in advance!

Thanks! Can you run make lint and commit? Should fix the tests

[ArtiomL]

OK got it.
I think everything is fixed now - could you please verify?
Thank you!

[jnordberg]

LGTM, have you verified that the option you added works as intended?

[ArtiomL]

Yes.

./ts-node ../../src/cli.ts ws://demos.kaazing.com/echo
NoSubProtocol
NoSubProtocol
^C

./ts-node ../../src/cli.ts ws://192.168.118.133:32773 -s echo
WithSubProtocol
WithSubProtocol
^C

Cheers!

For some reason Travis fails with Node v7:
https://travis-ci.org/jnordberg/wscat/jobs/313232015

It runs OK with Node v7 locally.

Error: listen EADDRINUSE :::41328 on their side?

Works now.
This tool is amazing!

Are you planning to publish to npm as well?

Thank you.
