Node.js File Upload API

Overview:

This Node.js application provides an API endpoint for uploading files to the server. It utilizes Express.js for handling HTTP requests, Multer for processing file uploads, and CORS for enabling cross-origin resource sharing.

Usage:

  1. Install Dependencies:
  2. Ensure you have Node.js installed on your system. Then, install the required dependencies by running:
  3. npm install express cors multer
  4. Clone the Repository:
  5. Clone or download this repository to your local machine.
  6. Navigate to the Directory:
  7. Open a terminal or command prompt and navigate to the directory containing the downloaded files.
  8. Run the Application:
  9. Execute the following command to start the Node.js server:
  10. node app.js
  11. This will start the server on port 8080 by default.
  12. Upload Files:
  13. You can upload files to the server by sending a POST request to the /uploads endpoint. Use a tool like Postman or write a client application to interact with the API programmatically.
  14. Example request using cURL:
  15. curl -X POST -F "files=@/path/to/file1.txt" -F "files=@/path/to/file2.txt" http://localhost:8080/uploads
  16. Response:
  17. Upon receiving the files, the server logs the request body and files to the console. It then responds with a JSON object indicating the status of the file upload.

Important Notes:

  • Ensure that the server has sufficient disk space and appropriate permissions to store uploaded files in the specified destination directory (./uploads).
  • Adjust the destination directory path in the Multer configuration (storage.destination) as needed.
  • This application includes CORS middleware to allow cross-origin requests. Make sure to configure CORS settings according to your requirements, especially in a production environment.
  • Multer is a middleware for handling multipart/form-data, commonly used for file uploads. It automatically parses incoming file uploads and makes them available as req.files object in the request handler.
  • For larger-scale applications, consider implementing additional security measures, such as file type validation and size restrictions, to prevent abuse and ensure data integrity.
