Redis Server implementation in Typescript

A simple implementation of a Redis server written in TypeScript. Part of my attempt at John Crickett's Coding Challenges

Features

• Basic implementation of Redis server functionality.
• Support for the RESP2 protocol.
• Support for common Redis commands.
• Autosave upon client disconnection or server shutdown.
• Loads DB for disk on startup.
• Asynchronous implementation.
• Easy to use and extend.

Installation

1. Clone the repository:

   git clone https://github.com/Fuad28/redis-server.git
   cd redis-server

2. Install dependencies using npm:

   npm init -y
   npm install

Usage

1. Run the Redis server:

   • option 1 : run server on default port 6379

   npm start

   • option 2 : specify a port to run server on.

    tsc && node dist/index.js -p 5000

2. The server begins to run on localhost port 6379. You can then interact with the server using redis-cli

   redis-cli

   You can then begin to send your commands.

Supported Commands

• PING: Ping the server.
• ECHO: Echo the input string.
• KEYS: Returns all key names.
• LEN: Returns the total number of keys stored.
• ECHO: Echo the input string.
• GET: Get the value of a key.
• SET: Set the value of a key.
• COMMAND: Get information about Redis commands (This wasn't implemented).
• EXISTS: Check if a key exists.
• DEL: Delete a key.
• DECR: Decrement the value of a key by 1.
• LPUSH: Add an element to the left end of a list.
• RPUSH: Add an element to the right end of a list.
• SADD: Add an element to a set.
• SMEMBER: Displays elements of a set.
• RPUSH: Add an element to the right end of a list.
• SAVE: Save the dataset to disk.
