Godis
Godis is a simple, probably naive, in-memory key-value database written in Go, for learning purposes. It is inspired by Redis, but it is not a Redis clone.
Protocol
Godis uses a websocket protocol to communicate between a client and the server. It exchanges JSON messages for commands and replies.
For example, sending a command to the server to set the key "example" to the string "hello, world" will respond with the reply of type ACK (for acknowledge) with the value "OK".
{ "o": "SET", [ "example" "hello, world" ] }
{ "t": "ACK", "v": "OK" }
