Radio

Radio is a Go (or Golang) library for creating RESP (REdis Serialization Protocol) compatible services/servers.

Features

• Fast Redis compatible server library
• Single RESP parser (radio.Reader) that can be used for both client-side and server-side parsing
• Parser supports Inline Commands to use with raw tcp clients (example: telnet)
• RESP value types to simplify wrapping values and serializing
• RESP Parser that can be used with any io.Reader implementation (e.g., AOF files etc.)
