Upload Handler Generator

File uploads are tricky. Validation, storage, progress tracking. This tool generates complete upload handling code for your stack. S3, local disk, Cloudflare R2. whatever you need.

One command. Zero config. Just works.

Quick Start

npx ai-upload "image upload to S3 with validation"

What It Does

Generates file upload handlers for Express, Fastify, or serverless
Includes file type validation and size limits
Supports S3, local storage, Cloudflare R2, and GCS
Creates presigned URL flows for direct uploads
Handles multipart uploads for large files

Usage Examples

# S3 upload with validation
npx ai-upload "images to S3 with 5MB limit and JPEG/PNG only"

# Local storage
npx ai-upload "documents to local disk with unique filenames"

# Presigned URLs for direct upload
npx ai-upload "presigned S3 URLs for client-side upload"

# Multiple file upload
npx ai-upload "bulk image upload up to 10 files"

# With progress tracking
npx ai-upload "large file upload with progress callback" --with-progress

Best Practices

Validate on both client and server - Never trust client-side validation alone
Use presigned URLs for large files - Don't proxy everything through your server
Set reasonable limits - Both file size and count per request
Scan for malware - Especially for user-uploaded executables

When to Use This

Adding profile picture uploads
Building document management features
Creating media libraries with file uploads
Implementing bulk import functionality
