openapi-to-ts2

English | 简体中文

openapi-to-ts2 is a tool to generate typings and service file based on openapi.

If you like it, please give me a star. Thanks a lot!

Features

• Compatible with bath OAS2 and OAS3
• Support major HTTP Client(axios and umi-request so far)
• Support generating js or ts file
• Support type system when generate ts file
• Plugin system to add global-level functionality

Install

npm install openapi-to-ts2

Example

note: CommonJS usage

In order to gain the TypeScript typings (for intellisense / autocomplete) while using CommonJS imports with require() use the following approach:

const OpenApiTool = require('openapi-to-ts2').default;

PS: Typing .default is merely used to gain the TypeScript typings. Please remove .default when you launch the project, otherwise it will throw an error.

Usage

const OpenApiTool = require('openapi-to-ts2');
const { resolve } = require('path');

const url = 'https://gw.alipayobjects.com/os/antfincdn/M%24jrzTTYJN/oneapi.json';
const outputDir = resolve(__dirname, 'service');

const openApiTool = new OpenApiTool({url});
openApiTool.generateService({
  template: 'axios',
  importText: `const axios = require('axios');`,
  typescript: true,
  outputDir,
});

API

new OpenApiTool(options: Options)

Create a new OpenApiTool instance.

Options:

Property	Description	Type	Default	required

data	The json of swagger document	string	-	either url or data

generateService(options: ServiceGeneratorOptions): void

Generate service files, the name of file will be the tag's name.

ServiceGeneratorOptions:

Property	Description	Type	Default	required
outputDir	Output directory	string	-	true
template	HTTP client template which you want to generate	string	'umi-request'	false
importText	Import statements	string	default statements	false
typescript	Generate ts file and typings	boolean	false	false
format	Format content of OpenApi	(openapi: OpenApi) => OpenApi	-	false

getOpenApi(): Promise<OpenApi>

Get OpenApi that transformed from OAS2/OAS3.

Plugin

openapi-to-ts2 have a flexible plugin system which can add global-level functionality.

Using Plugin

Use plugins by calling the OpenApiTool.use() global method. This has to be done before you start your app by calling new OpenApiTool():

// calls `MyPlugin.install(OpenApiTool)`
OpenApiTool.use(MyPlugin)

new OpenApiTool({
  //... options
})

You can optionally pass in some options:

OpenApiTool.use(MyPlugin, { someOption: true })

Writing a plugin

A plugin should be a method. The method will be called with the OpenApiTool constructor as the first argument, along with possible options:

const logPlugin = (OpenApiTool, option) => {
  OpenApiTool.prototype.log = async function() {
    const openapi = await this.getOpenApi();
    console.log(`the length of apis: ${openapi.apis.length}`);
    console.log('option', option);
  }
}

then you can use it like this:

const openApiTool = new OpenApiTool({
  //... options
});
openApiTool.log();
