  • Handles multiple client connections concurrently
  • Implements core Redis commands:
    • PING
    • ECHO <message>
    • SET <key> <value> [EX seconds|PX milliseconds]
    • GET <key>
    • TTL <key>
  • Supports key expiry with EX (seconds) and PX (milliseconds) options
  • Thread-safe in-memory key-value store

Clone the repository

git clone https://github.com/your-username/redis-go.git
cd redis-go/app

Build and Run

go build -o redis-server main.go connection.go resp.go server.go
./redis-server
