Typescript definition file to make axios work with nock

Axios Nock and Typescript.md

Axios, Nock, and Typescript

There is a documented issue describing how axios and nock do not work well together. The workaround described in this comment works.

import axios from 'axios';
import httpAdapter from 'axios/lib/adapters/http';
import nock from 'nock';

axios.defaults.adapter = httpAdapter;

// Some tests using nock ...

The problem with this solution is that Typescript complains httpAdapter from axios/lib/adapters/http implicitly has the any type. To combat this, add a definitions file to your project with the contents of axios.d.ts.

axios.d.ts

declare module 'axios/lib/adapters/http' {
  import { AxiosAdapter } from 'axios';

  const httpAdapter: AxiosAdapter;
  namespace httpAdapter { }

  export = httpAdapter;
}
