Node.js library that generates Typescript clients based on the OpenAPI specification.

Why?

  • Frontend ❤️ OpenAPI, but we do not want to use JAVA codegen in our builds
  • Quick, lightweight, robust and framework-agnostic 🚀
  • Supports generation of TypeScript clients
  • Supports generations of Fetch, Node-Fetch, Axios, Angular and XHR http clients
  • Supports OpenAPI specification v2.0 and v3.0
  • Supports JSON and YAML files for input
  • Supports generation through CLI, Node.js and NPX
  • Supports tsc and @babel/plugin-transform-typescript
  • Supports aborting of requests (cancelable promise pattern)
  • Supports external references using json-schema-ref-parser
