Node File Upload

A guide to handling file uploads securely and efficiently in Node.js APIs with validation and cloud storage integration.

Usage

Ask about file upload handling, Multer configuration, cloud storage, or upload security.

Examples

  • "Set up file uploads with Multer and S3 storage"
  • "How do I validate file types and sizes?"
  • "Stream large file uploads to cloud storage"

Guidelines

  • Always validate file type, size, and content before processing
  • Use streaming uploads for large files to avoid memory issues
  • Store files in cloud storage, not on the application server
  • Generate unique file names to prevent collisions
  • Implement virus scanning for user-uploaded files
