Simple chat functionality: Each connection needs to identify themselves first using a simple json having an id. After id has been authorised, you can send messages as per the following format: {"recipients":[x,y],"sender":"x","message":"sample message"} We cant send messages unless identification has been done. Client 1:

wscat -c ws://localhost:8080/message
> {"id":"1"}
< hello 1
> {"recipients":[1,2], "sender":"1", message:"hi how are you"}
< 1 -> hi how are you
< 2 -> im good

Client 2:

wscat -c ws://localhost:8080/message
> {"id":"2"}
< hello 2
< 1 -> hi how are you
> {"recipients":[1,2], "sender":"2", message:"im good"}
< 2 -> im good 

Basic:

curl -X GET http://localhost:8080/simple-greet

JSON:

curl -X GET http://localhost:8080/greet
{"message":"Hello World!"}

curl -X GET http://localhost:8080/greet/Joe
