Mask the map with a mapbox gl circle layer

Question

Is there a way to mask the whole map using a Mapbox GL Circle Layer? I cant find any examples or useful links.

I was able to add a mask layer using Mapbox GL GeoJSON layer

Answer 1

There is no built-in functionality to do this in GL JS.

I recommend creating the circle mask in GeoJSON. turf-circle should make this relatively easy.
