ViewStateProps Typescript object has missing type options for zoom

[alexjbuck]

Description

If your View is an Orthographic View then the zoom can be a [number,number] type to denote independent x and y zoom values. In practice this works, however the ViewStateProps type is defined with zoom?: number so ts throws an type-checking error if you defined zoom = [1,1] for example, in a ViewStateProps object.

Type 'number[]' is not assignable to type 'number'

Minimal example to be used with an OrthographicView:

  const [viewState, setViewState] = useState<ViewStateProps>({
    maxZoom: 4,
    minZoom: -4,
    target: [0, 0],
    zoom: [0, 0],
  });

Flavors

• Script tag
• React
• Python/Jupyter notebook
• MapboxOverlay
• GoogleMapsOverlay
• CartoLayer
• ArcGIS

Expected Behavior

I expect to be able to provide either number or number[] to the zoom prop in a ViewStateProps object.

Steps to Reproduce

Minimal example to be used with an OrthographicView:

import { ViewStateProps } from "@deck.gl/core/lib/deck";

  const [viewState, setViewState] = useState<ViewStateProps>({
    maxZoom: 4,
    minZoom: -4,
    target: [0, 0],
    zoom: [0, 0],
  });

Environment

• Framework version: "@deck.gl/core": "8.9.32",
