Tinkering with Websocket

I'm in the middle of working with websocket and still kinda new.
I understand what Websocket is in the surface but blindly know nothing under the hood. This repo should stash away my tinkering-websocket journey so far.

Objectives

• faketime chat, that delaying message delivery. The delay time may adjusted to zero means it realtime.
• understand how to use autobahn test suite, create a report and interpret it.

Tools and Library

• websocat: more advanced netcat-like utility written in rust.
• wscat: netcat-like utility to listen incoming websocket request or connect as client.
• websockets: a python library that support client/server websocket, readme: here.
• gorilla websocket: a golang library that upgrade incoming HTTP request into websocket. It supports dialling a websocket too.
• websocket/ws: a NodeJS websocket library.
• golang net/websocket

References

• MDN Web API Websocket

Notes

The transmitted data message can be text, binary or control message. There three control messages:

• /close 1006
• /ping
• /pong

Whenever a ping request accepted, the websocket entity should response with pong control message. The ping/pong control message acts as heartbeat and probes the healthiness of a connection.
