OpenAPI Typescript Codegen

This is a Fork of openapi-typescript-codegen with the following changes:

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

Install

npm install openapi-typescript-codegen --save-dev
