Simple Redis

Overview

The Simple Redis implementation in Go serves as a minimalist, educational example of a Redis-like key-value store. This server is compatible with redis-cli and supports the following commands:

• PING
• ECHO
• SET (with PX and EX options for setting expiry)
• GET
• DEL

Requirements

• Go 1.20 or higher

Running the Server

To run the server, navigate to the ./simple-redis directory and execute the following command:

go run main.go

This will start the Simple Redis server, which listens on port 6379 by default.

Usage

To interact with the Simple Redis server, you can use the official redis-cli.

For example, after starting the server, open a new terminal and run:

redis-cli

Inside the Redis CLI, you can then execute the following commands:

PING

PING hello

ECHO

ECHO "Hello, World!"

SET

Set a value with no expiry:

SET key value

Set a value with an expiry of 1000 milliseconds:

SET key value PX 1000

Set a value with an expiry of 10 seconds:

SET key value EX 10

GET

GET key

DEL

DEL key

Code Structure

• main.go: Entry point of the application, initializes the server.
• commands.go: Contains the implementations for the Redis commands.
• parser.go: Contains utility functions for parsing Redis commands and arguments.
• utils.go: Contains utility functions for the server.
