openapi-to-typescript

To generate TypeScript types from an OpenAPI specification, provide the file path to automatically convert components.schemas and paths into strongly-typed interfaces and type guards. The tool resolves $ref references and outputs a cohesive typed definitions file.

Yes, you can create type guards from OpenAPI 3.0 definitions automatically. The conversion process reads your API specification and generates robust type guards alongside TypeScript interfaces to ensure strongly-typed API validation workflows.

Yes, TypeScript codegen supports both JSON and YAML OpenAPI documents. The automated conversion applies to API design, client generation, and validation workflows across both formats to produce cohesive typed definitions.

When converting OpenAPI to TypeScript, $ref references are resolved across schemas and paths to produce cohesive types. This ensures that all linked definitions in your API specification are accurately translated into a single strongly-typed file.

The best way to automate type safety for an API client is to generate TypeScript interfaces and type guards from your OpenAPI spec. This removes manual translation errors and outputs a typed definitions file for easy integration.

The generated TypeScript interfaces and type guards are output to a single strongly-typed file, such as types/api.ts. This consolidated output file contains all definitions resolved from your OpenAPI components and paths for easy integration.
