Readme
@spec2ts/openapi
@spec2ts/openapi
is an utility to create TypeScript types from OpenAPI v3 specification. Unlike other code generators @spec2ts/openapi
does not use templates to generate code but uses TypeScript's built-in API to generate and pretty-print an abstract syntax tree (AST).
Features
- AST-based: Unlike other code generators
@spec2ts/openapi
does not use templates to generate code but uses TypeScript's built-in API to generate and pretty-print an abstract syntax tree. - Tree-shakeable: Individually exported types allows you to bundle only the ones you actually use.
- YAML or JSON: Use YAML or JSON for your OpenAPI v3 specification.
- External references: Resolves automatically external references and bundle or import them in generated files.
- Implementation agnostic: Use generated types in any projet or framework.
Installation
Install in your project:
npm install @spec2ts/openapi
