Is there a way to pass basic auth header options when retrieving a deck.gl layer?

Question

I am looking to create an MVTLayer from a private repository that is wrapped with a basic authorization header. I was looking through the source code and don't see a way to pass additional header options to the POST. Is there a way to pass a header when retrieving a deck.gl layer?

Answer 1

Take a look at the loadOptions property of MVTLayer. Anything you pass in there will get passed through to the native fetch.

For example,

const myLayer = new MVTLayer({
  // ...
  loadOptions:
    fetch: {
      headers: {
        Authorization: 'Basic ' + btoa('login:password'))
      }
    }
  }
});
