c++ fast websocket + json parser

Hello,

I need a low latency implementation (preferably header only) class that i can import in my existing project directly.

This class has to be able to connect to a websocket server that is streaming a lot of data, authenticate*, subscribe, receive and parse it as fast as possible. The data sent is in json, (sometimes html if errors appear).

Server: wss://[login to view URL]

after connection subscribe like that: {"op": "subscribe", "args": ["orderBookL2:XBTUSD"]}

for more details: [login to view URL]

Ideal would be a custom solution written from scratch that uses raw sockets but could accept implementations that use uWebsockets, pjson, rapidjson libs if you explain why that would be faster. Essentially i need to get the data, parse it fast and address it easily in my existing program.

Skills: C++ Programming, C Programming
