FAQPage Schema
How do I convert an OpenAPI spec to TypeScript interfaces?▼

To convert OpenAPI specs to TypeScript interfaces, provide an OpenAPI 3.0.x file path. The tool extracts schemas from components/schemas and endpoints from paths to generate TypeScript interfaces, types, and runtime type guards.

Can I generate runtime type guards from OpenAPI schemas?▼

Yes, you can generate runtime type guards from OpenAPI schemas. The generated TypeScript output includes runtime guards alongside interfaces and types, ensuring contract accuracy and validating data for client code.

Does this codegen tool resolve $ref references in OpenAPI 3.0 YAML files?▼

Yes, this OpenAPI 3.0 codegen tool resolves $ref references. It validates essential fields within your JSON or YAML OpenAPI 3.0.x file before producing the final TypeScript file with interfaces and guards.

What is the best way to keep frontend and backend OpenAPI contracts synchronized?▼

The best way to keep frontend and backend contracts synchronized is converting OpenAPI specifications into TypeScript interfaces. This reduces manual typing, preserves JSDoc comments from OpenAPI descriptions, and ensures type accuracy.

Are JSDoc comments preserved when generating TypeScript types from OpenAPI?▼

Yes, JSDoc comments are preserved when generating TypeScript types from OpenAPI. The tool extracts descriptions from your OpenAPI 3.0 schemas and paths, documenting the generated TypeScript interfaces and types with JSDoc.
