📁 File Management Platform

This project is a comprehensive summary of the back-end trimester topics, covering authentication, NodeJS, MongoDB, Redis, pagination, and background processing. The objective is to build a simple platform for uploading and viewing files with functionalities such as user authentication via a token, listing all files, uploading new files, changing file permissions, viewing files, and generating thumbnails for images.

Project Overview

---

The File Management Platform is designed to provide users with the ability to manage their files securely and efficiently. It includes features such as:

• User authentication using tokens.
• Listing all uploaded files.
• Uploading new files.
• Changing file permissions.
• Viewing files.
• Generating thumbnails for image files.

Features

---

• 🔐 User Authentication: Secure authentication mechanism using tokens.
• 📄 File Listing: List all uploaded files with pagination.
• 📤 File Upload: Upload new files to the platform.
• 🔄 Permission Management: Change the permissions of files (e.g., private, public).
• 👁️ File Viewing: View the content of uploaded files.
• 🖼️ Thumbnail Generation: Generate and view thumbnails for image files.
• ⚙️ Background Processing: Use background workers for processing tasks such as thumbnail generation.

Learning Objectives

---

By the end of this project, you should be able to:

1. Create an API with Express:

   • Set up a Node.js server with Express.
   • Define API endpoints for file management.

2. Authenticate a User:

   • Implement token-based authentication.
   • Secure API endpoints using authentication middleware.

3. Store Data in MongoDB:

   • Connect to a MongoDB database.
   • Perform CRUD operations on MongoDB collections.

4. Store Temporary Data in Redis:

   • Set up Redis for caching and temporary data storage.
   • Use Redis for session management and caching.

5. Setup and Use a Background Worker:

   • Implement background processing using a worker library (e.g., Bull).
   • Process tasks such as thumbnail generation in the background.

Technologies Used

---

• Node.js: JavaScript runtime for building the server.
• Express.js: Web framework for building APIs.
• MongoDB: NoSQL database for storing file metadata.
• Redis: In-memory data structure store for caching and temporary data.
• Bull: Background job processing library.
• Multer: Middleware for handling file uploads.
• JWT: JSON Web Tokens for user authentication.

Setup and Installation

---

1. Clone the Repository:

   git clone https://github.com/your-username/file-management-platform.git
   cd file-management-platform
   
   

2. Install Dependencies:

   npm install
   
   

3. Set Up Environment Variables: Create a .env file in the root directory and add the following environment variables:

   PORT=3000
   MONGODB_URI=mongodb://localhost:27017/file_management
   REDIS_URL=redis://localhost:6379
   JWT_SECRET=your_jwt_secret
   

4. Start the Server:

   npm start
