🚀 mini-redis-ts

A lightweight Redis clone implemented in TypeScript, featuring core Redis commands and key expiration functionality.

✨ Features

• Core Redis commands implementation:
  • PING - Server healthcheck
  • ECHO - Echo back messages
  • GET - Retrieve stored values
  • SET - Store key-value pairs with optional expiry
• Key expiration support using PX milliseconds option
• RESP (Redis Serialization Protocol) compliance
• Written in TypeScript for type safety and better developer experience

🛠️ Installation

# Clone the repository
git clone https://github.com/yourusername/mini-redis-ts.git

# Navigate to project directory
cd mini-redis-ts

# Install dependencies
npm install

# Build the project
npm run dev

📝 Usage

The server runs on localhost:6379 by default, making it compatible with the standard Redis CLI:

# Using redis-cli
redis-cli

# Basic commands
> PING
PONG

> SET mykey "Hello World"
OK

> GET mykey
"Hello World"

# Set with expiration (5000 milliseconds)
> SET mykey "Hello World" PX 5000
OK

> GET mykey  # Returns value
"Hello World"

# After 5 seconds...
> GET mykey  # Returns nil
(nil)
