openapi2ts

openapi2ts is a Node.js module that generates TypeScript interfaces from an OpenAPIv3 schema. It exports a parse function that takes an Options object as input and generates a .ts file containing TypeScript interfaces. The module also includes a CLI interface for parsing OpenAPI schema files and generating TypeScript interface files.

Installation

To install openapi2ts, you need to have Node.js and npm installed on your machine. Then, run the following command:

npm i @soluzioni-futura/openapi2ts

Usage

Module interface

The module exports a single function parse which generates a TypeScript file from an OpenAPIv3 schema. The parse function takes an Options object as input and returns a Promise that resolves to an object containing at key data the generated TypeScript file as a string and at key exports a set of all exported type names. Here's an example of how to use the parse function:

import { parse, Options } from "openapi2ts";

const options: Options = {
  openapi: "path/to/openapi.json",
  outputFilePath: "path/to/output.ts",
  bannerComment: `/* My Banner Comment */`
};

parse(options)
  .then((data: string) => {
    console.log(data);
  })
  .catch((err: any) => {
    console.error(err);
  });

The Options object has the following properties:

• openapi: the path to the OpenAPIv3 schema file or the schema object itself. This property is required.
• outputFilePath: the path to the output TypeScript file. If this property is not provided, the generated TypeScript file will not be saved to disk.
• bannerComment: a banner comment that is added at the top of the generated TypeScript file. If this property is not provided, a default banner comment will be used.

CLI Interface

The module also includes a CLI interface that can be used to parse an OpenAPI schema file and generate a TypeScript interface file. Here's an example of how to use the CLI:

openapi2ts path/to/openapi.json path/to/output.ts
