I saw that suggestion by "chrisma" on a Stack Overflow answer https://stackoverflow.com/questions/64466331/is-it-possible-advisable-to-run-rails-6-without-webpacker but it seems to still have some webpack bits around. Do I just have to accept this and delete them manually?

When I cloned this from GitHub I was pleasantly surprised to not see webpacker or Node.Js stuff, the project folder for this Hotwire project is around 13MB rather than 124MB for a new Rails 6 project.

Can anybody tell me how to setup a new Rails 6 project using Hotwire WITHOUT Webpacker and Node.js?

You may need to install Redis. See this section https://hixonrails.com/ruby-on-rails-tutorials/ruby-on-rails-redis-installation-and-configuration/#redis-installation
