ADVANCE FILE SERVER WITH SECURE AUTHENTICATION

A robust, full-stack application that provides a secure platform for users to upload, manage, and share their files. This project builds upon a complete authentication system to ensure that all file operations are protected and user-specific.

Project Overview

I developed an advanced file server with a primary focus on security and user control. The system allows authenticated users to securely upload their files, which are then stored and managed in a way that only the original owner has access. This creates a personal and secure cloud storage solution.

Technologies Used

Frontend

• ReactJS: For building the dynamic user interface and file upload components.
• React Router: For handling client-side routing and protecting authenticated routes.
• Axios: For making HTTP requests to the backend, including file uploads.
• React Context API / Redux Toolkit: For managing global authentication state.
• CSS / UI Library: For styling and creating a responsive file management interface.

Backend

• ExpressJS: The core framework for building the RESTful API.
• jsonwebtoken (JWT): For creating and verifying access tokens to manage user sessions and secure API endpoints.
• bcrypt.js: For securely hashing user passwords.
• Mongoose: For managing user data and file metadata (e.g., filename, owner, upload date).
• dotenv: For managing environment variables and keeping sensitive data secure.
• Multer: A middleware for handling multipart/form-data, used for uploading files.
• Cloud Storage (e.g., AWS S3, Cloudinary): For scalable and reliable file storage, separating application logic from file assets. (Alternatively, files can be stored on the server's local file system).

Key Features

• Full Authentication System: Includes secure user registration, login, and logout functionalities.
• Protected Routes: All file-related endpoints and frontend pages are protected, requiring a valid JWT for access.
• Secure File Upload: Users can upload files through a dedicated interface, with files being processed and stored securely.
• User-Specific File Dashboard: Upon logging in, users are presented with a dashboard listing only their own uploaded files.
• File Management: Users can view file details (name, size, upload date), download their files, and delete them permanently.
• Access Control: The backend enforces strict access control, preventing users from accessing, viewing, or modifying files belonging to other users.

Project Highlights

This project demonstrates my ability to integrate complex functionality like file handling with a secure authentication system. It showcases my skills in backend API design, database management for file metadata, and creating a secure, user-centric experience where data privacy and integrity are paramount.
