# 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 ## Part of the LXGIC Dev Toolkit This is one of 110+ free developer tools built by LXGIC Studios.
