Sendify

Sendify is a file-sharing application that enables users to upload large files and share them securely via generated download links and QR codes. It comes with automatic file expiration and deletion, making it a practical solution for temporary file sharing needs. Features - File Upload: Upload files up to 15GB. - File Sharing: Generate shareable links with QR codes. - Auto Deletion: Files are automatically deleted after a configurable expiration time (default: 12 hours). - Simple UI: A minimalistic and user-friendly interface for both uploading and downloading files. - Cross-Origin Request Handling (CORS): Proper CORS support for frontend-backend communication. Tech Stack - Backend: Node.js, Express.js - File Handling: Formidable - QR Code Generation: qrcode library - File Deletion: Custom script for auto-deleting files after expiration - Frontend: HTML, CSS, JavaScript (React/Vue can be used if extended) - Environment Variables: .env for configurations Installation Prerequisites - Node.js installed on your machine. - A .env file for setting environment variables like UPLOADS_DIR (file storage path) and EXPIRE_TIME (file expiration time in milliseconds). Steps to Run Locally 1. Clone the Repository: git clone https://github.com/your-username/sendify.git cd sendify 2. Install Backend Dependencies: cd backend npm install 3. Install Frontend Dependencies: cd ../frontend npm install 4. Configure Environment Variables: In the backend folder, create a .env file and add the following variables: UPLOADS_DIR=./uploads EXPIRE_TIME=43200000 # 12 hours in milliseconds PORT=3001 FRONTEND_URL=http://localhost:3000 5. Start the Backend Server: cd backend node server.js This will start the backend server on http://localhost:3001. 6. Start the Frontend Server: cd ../frontend npm start The frontend will now be accessible at http://localhost:3000. Usage Upload a file: - Open the frontend page and select a file to upload. - Click "Upload" to initiate the upload process. - After the file is uploaded, you will receive a download link along with a QR code for easy sharing. Download a file: - Use the generated download link or scan the QR code to download the file. File Expiration and Auto Deletion: - Uploaded files will automatically expire after the set time (12 hours by default). The file will be deleted from the server once the expiration time is reached. File Deletion Files are automatically deleted based on the expiration time set in the .env file. This ensures that files are not stored indefinitely, helping to save server space.
