Since the time of recording, the esbuild-rails library has been archived in favor for jsbundling-rails which combines esbuild, rollupjs and webpacker into a single library. You should be able to use this instead with the new syntax found at https://github.com/rails/jsbundling-rails
In addition to the jsbundling, we also now have cssbundling-rails
What this means as far as this episode content goes, is that I would no longer include the node_modules in the assets, but rather just import bootstrap into my stylesheets.
With the addition of this gem, we are given a few additional options in the generators.
