TCP Key-Value Store in Go

This project is a simple in-memory key-value store running on top of TCP.

Clients connect to the server over TCP and send plain text protocol commands.

Run the server

go run ./cmd

Protocol commands

• PUT <key> <value>: Store a value for a key.
• GET <key>: Retrieve the value for a key.
• DEL <key>: Delete a key-value pair.
• LIST: List all key-value pairs as key=value lines.

Connect and send commands

To interact with the server, use any TCP client tool such as telnet or nc (netcat), then pass your commands.

Examples:

• One-shot with nc: echo "PUT name sean" | nc localhost 8080
• One-shot with nc: echo "GET name" | nc localhost 8080
• Interactive with telnet: telnet localhost 8080 and then type commands like PUT city sf, GET city, or LIST.
