@tschaub thanks! I tried again with no luck. It's probably because of my lack of administrative priviledges with my particular machine with regards to npm libraries. I tried Vite and it worked great! Thanks for the suggestion!
@eflowbeach - Give it a try again now. It looks like
webpack-nanono longer works (openlayers/ol-webpack#61 useswebpack-cliinstead). The setup in that repo is very bare bones. You can use a dev server, configure loaders, etc. just as you would with another webpack project.If you aren't already attached to webpack, I'd suggest vite as an alternative (see https://github.com/openlayers/ol-vite).
