openapi-axios

A code generator that converts OpenAPI 2.0/3.0/3.1 specifications into type-safe Axios functions with full TypeScript support. Current stable version is 0.34.0, released on a continuous cadence. Key differentiators include optional request/response validation via Zod, support for generating intermediate schema files, and built-in API mocking capabilities. It uses the OpenAPI spec to generate strongly typed request functions that integrate seamlessly with Axios, enabling tree-shaking and type safety.
