Question

This works, but it was a stab in the dark. I know little Ruby.

What’s the accepted way to serve a plain old file for a given resource?

get '/xyz' do
    File.read 'abc.html'
end

Answer 1

you can use set :public to specify the directory for your static files. Then, you can serve the file using send_file() for example:

    get '/static_file' do
      send_file('my_static_file')
   end
