description: Generate OpenAPI specs from Express routes. Use when documenting APIs.

Swagger Generator

Your API has no documentation. This reads your Express routes and generates a complete OpenAPI 3.0 spec.

One command. Zero config. Just works.

Quick Start

bash
npx ai-swagger ./src/routes/

What It Does

  • •Reads your Express route files
  • •Generates OpenAPI 3.0 specification
  • •Documents request/response shapes
  • •Ready for Swagger UI

Usage Examples

bash
# Generate from routes
npx ai-swagger ./src/routes/

# Single file
npx ai-swagger ./src/routes/users.ts -o docs/api.yaml

Best Practices

  • •Keep it updated - regenerate when routes change
  • •Add descriptions - explain what endpoints do
  • •Include examples - show sample requests
  • •Document errors - not just happy paths

When to Use This

  • •Creating API documentation
  • •Setting up Swagger UI
  • •Onboarding API consumers
  • •API-first design
