Openapi Typescript | Awesome Repository

openapi-typescript is an OpenAPI TypeScript type generator and schema transformer. It converts JSON or YAML OpenAPI specification files into static TypeScript type definitions to provide end-to-end API type safety.

The tool functions as a static type generator that transforms external API definitions into interfaces and types. It focuses on zero-runtime type enforcement, ensuring that data consistency is maintained via the TypeScript type system without adding overhead to production bundles.

The project covers API type safety and schema conversion, facilitating the validation of request bodies and responses against a defined schema. It supports client-side validation and frontend API integration by verifying that network calls and mock data adhere to the structures defined in an OpenAPI document.

Features

Static Type Generators - Generates static TypeScript definition files from API schemas to provide compile-time safety without runtime overhead.
OpenAPI to Type Conversions - Transforms JSON or YAML API specifications into static type definitions for frontend and backend use.
OpenAPI Specification Parsers - Provides the core logic for ingesting and normalizing OpenAPI JSON or YAML specification files.
Type Safety - Implements architectural patterns that propagate API type definitions across the entire application stack.
