Middleware Generator

Writing middleware means handling edge cases, async errors, and weird Express patterns. Describe what you need and get production-ready middleware.

One command. Zero config. Just works.

Quick Start

npx ai-middleware "rate limit 100 req/min per IP"

What It Does

Generates Express middleware from descriptions
Handles rate limiting, auth, logging, and more
Includes proper error handling
TypeScript support built in

Usage Examples

# Rate limiting
npx ai-middleware "rate limit 100 req/min per IP"

# JWT auth
npx ai-middleware "JWT auth with role-based access" -t

# Request logging
npx ai-middleware "request logging with response time" -o logger.ts -t

# API key validation
npx ai-middleware "validate API key from header"

Best Practices

Order matters - put auth before route handlers
Handle errors - don't let middleware crash the server
Keep it focused - one middleware, one job
Test thoroughly - middleware affects every request

When to Use This

Adding new middleware to an API
Need common patterns like rate limiting
Learning middleware best practices
Prototyping API features quickly
