Redis Queue Processing with Express and TypeScript

This project demonstrates a basic queue processing system using Redis, Express, and TypeScript. It includes two main components:

1. Server: Handles incoming code submissions and pushes them to a Redis queue.
2. Worker: Processes submissions from the Redis queue asynchronously.

Getting Started

Prerequisites

• Node.js (version 14 or above)
• Redis (running locally or remotely) or

docker run --name myredis -d -p 6379:6379 redis

Installation

1. Clone the repository:

   git clone https://github.com/your-username/redis-queue-impl.git

2. Navigate to the project directory:

   cd redis-queue-impl

3. Install the dependencies:

   npm install

Running the Server

1. Start the Redis server.
2. Run the Express server:

   cd express-be
   npx tsc -b
   node dist/index.js

3. The server will be running on http://localhost:3000.

Running the Worker

1. Start the Redis server (if not already running).
2. Run the worker:

   cd worker
   npx tsc -b
   node dist/index.js
