When to Use Scaffolding new projects or components Generating repetitive boilerplate code Creating CRUD operations automatically Generating API clients from OpenAPI specs Building code from templates Creating database models from schemas Generating TypeScript types from JSON Schema Building custom CLI generators Quick Start Minimal working example: Reference Guides Detailed implementations in the references/ directory: Guide Contents [Template Engines](references/template engines.md) Template Engines [AST Based Code Generation](references/ast based code generation.md) AST Based Code Generation [Project Scaffolding](references/project scaffolding.md) Project Scaffolding [OpenAPI Client Generation](references/openapi client generation.md) OpenAPI Client Generation [Database Model Generation](references/database model generation.md) Database Model Generation [GraphQL Code Generation](references/graphql code generation.md) GraphQL Code Generation [Plop.js Generator](references/plopjs generator.md) Plop.js Generator Best Practices ✅ DO Use templates for repetitive code patterns Generate TypeScript types from schemas Include tests in generated code Follow project conventions in templates Add comments to explain generated code Version control your templates Make templates configurable Generate documentation alongside code Validate inputs before generating Use consistent naming conventions Keep templates simple and maintainable Provide CLI for easy generation ❌ DON'T Over generate (avoid unnecessary complexity) Generate code that's hard to maintain Forget to validate generated code Hardcode values in templates Generate code without documentation Create generators for one off use cases Mix business logic in templates Generate code without formatting Skip error handling in generators Create overly complex templates
