I downloaded ArduinoWebSockets/ESP32-Server to serve as a beginning websocket server. (I got it from the Examples.) Having pasted it into a sketch, I tried compiling it. Of course it wouldn't, but the thing I'm having the most trouble with is: It's all pre-compile instructions with no actual code. At present the compiler is complaining about lack of both setup() and loop() routines.
Is there supposed to be any code with this? Are there any complete websocket server sketches available for ESP32?
