Simple Redis Implementation

This project is a simple implementation of Redis in JavaScript. It uses Node.js and the net module to create a TCP server that can handle Redis commands.

Features

  • Bind to a Port: The server is set to listen on port 6379, which is the default port for Redis.

  • Respond to PING: The server can respond to a PING command with a PONG.

  • Respond to Multiple PINGs: The server can handle multiple PING commands concurrently.

  • Handle Concurrent Clients: The server uses Node.js's event-driven, non-blocking I/O model, which makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

  • Implement the ECHO Command: The server can respond to an ECHO command by sending back the same message.

  • Implement the SET & GET Commands: The server can store key-value pairs with the SET command and retrieve the value with the GET command.

  • Expiry: The server can handle key expiry. If a timeout is provided with the SET command, the key will be deleted after the specified time.

Running the Server

To run the server, execute the following command:

node main.js

This will start the server and bind it to port 6379. You can then connect to it using a Redis client and execute commands.
