Current behavior

The method setBasePath(basePath: string) is missing in the current (4.0.9) @nestjs/swagger version.

Expected behavior

Have a method to set base path as it was in older versions, for example (3.1.0)

Minimal reproduction of the problem with instructions

const options = new DocumentBuilder()
  .setTitle('example')
  .setBasePath('/example')
  .build();

will result 'Property ‘setBasePath’ does not exist on type ‘DocumentBuilder’

What is the motivation / use case for changing the behavior?

Have the ability to set swagger with base path

Environment

Nest version: Nest version: @nestjs/swagger@4.0.9
 
For Tooling issues:
- Node version: 12.14.0 (LTS)
- Platform:  Mac and Windows

setBasePath is no longer required (a global path will be populated automatically). If you want to have more control over that, you can use addServer.

For better developer experience, I’ve added depracated setBasePath in 4.1.1 release to inform devs on how to migrate from the previous API.
