Thanks @helgasoft -- the dependencies aren't missing, they're just attached differently as of v2.2.0. The change was mentioned in the changelog for the v2.2.0 release.

[helgasoft]

Ok, version 2.2.0 says "the HTML dependencies for leaflet() are included in the dependencies item of the htmlwidget object it returns.". And they are there:

map <- leaflet(quakes[1:33,]) |> addTiles() |> addMarkers()
map$dependencies

But my library attempts to read them before any leaflet htmlwidget is actually built. Is there a way to do that, like with v.2.1.0 shown above ? ANSWER: leaflet()$dependencies
