This is a simple Redis-like in-memory key-value store built using Node.js and TCP sockets.

Features

• PING: Replies with PONG
• ECHO: Replies with the same message
• SET key value: Stores the key-value pair
• SET key value PX milliseconds: Stores the key-value pair with expiry
• GET key: Retrieves the value for the key (if not expired)

🛠 Setup

Make sure you have Bun installed.

bun install
bun run dev

This starts the TCP server on port 6379.

🧪 Test with nc (Netcat)

You can use netcat to send raw RESP (Redis Serialization Protocol) commands.
