How to extend Dispatcher.HttpMethod typescript definition?

[dkatashev]

Hello,

I want to use this library to perform HTTP calls to WebDAV.
This protocol use their own HTTP Methods such as: COPY, MKCOL, etc.
Currently, type definitions are limit me to use only normal REST HTTP methods.

What I already tried:

1. Bypass Typescript checking:

import { request } from 'undici';

request('https://some.webdav.com', {
  // eslint-disable-next-line @typescript-eslint/no-explicit-any
  method: 'MKCOL' as any
});

2. Tried module augmentation but it is not working:

declare module 'undici' {
  namespace Dispatcher {
    interface DispatchOptions {
      method?: HttpMethod;
    }

    type HttpMethod = string;
  }
}

Could you help me?

Hey! You need to augment the RequestOptions interface, not the DispatchOptions one. As follows:

import { request } from 'undici';

declare module 'undici' {
  namespace Dispatcher {
    interface RequestOptions {
      method: HttpMethod | 'MKCOL';
    }
  }
}

request('http://localhost:3000', {
  method: 'MKCOL',
});
