Axios support

This tool allows you to generate a client based on the Axios client. The advantage of the Axios client is that it works in both Node.js and Browser based environments. If you want to generate the Axios based client then you can specify --client axios in the openapi call:

openapi --input ./spec.json --output ./generated --client axios

The only downside is that this client needs some additional dependencies to work (due to the missing FormData classes in Node.js).

npm install axios --save-dev
npm install [email protected] --save-dev

In order to compile the project and resolve the imports, you will need to add the following properties in your tsconfig.json file:

{
    "compilerOptions": {
        "lib": ["...", "dom"],
        "allowSyntheticDefaultImports": true
    }
}

Using a custom Axios client

Sometime you may want to use your own Axios client created by axios.create for advanced configuration (e.g. Usage of the popular axios-retry interceptor) without having to reimplement the entire generated Axios request function.

In those cases, simply construct your own HttpRequest wrapper implementation and pass it into your API client

Example

Create a file that looks like this, that references file from the /core folder of the generated client.

import axios from 'axios';
import axiosRetry from 'axios-retry';
import { request as __request } from './request';
import { CancelablePromise } from './CancelablePromise';
import { BaseHttpRequest } from './BaseHttpRequest';
import { ApiRequestOptions } from './ApiRequestOptions';
import type { OpenAPIConfig } from './OpenAPI';


export class AxiosHttpRequestWithRetry extends BaseHttpRequest {
  axiosInstance = axios.create();

  constructor(config: OpenAPIConfig) {
    super(config);
    axiosRetry(this.axiosInstance);
  }

  public override request<T>(options: ApiRequestOptions): CancelablePromise<T> {
    return __request(this.config, options, this.axiosInstance);
  }
}

Then, when instantiating your generated test client, pass in your custom request wrapper class:

import { AxiosHttpRequestWithRetry } from './AxiosRequestWithRetry';
import { GeneratedClient } from './generated/client';

const client = new GeneratedClient({ BASE: 'http://localhost:8123' }, AxiosHttpRequestWithRetry)
