Changing webpage goes to directory listing

[ROBYER1]

Running the index.html of a website with sub pages, when I click a link to a page it takes me to the directory listing of that page and not the index.html of that page. Is there any way to adjust this behaviour?

Yeah, there are a few options. You can use directory_listing: false [1] and create a custom handler like this:

class IndexFileHandler < HTTP::StaticFileHandler
  def call(context)
    request_path = context.request.path.not_nil!
    
    if request_path.ends_with?("/")
      new_path = Path[request_path].join("index.html").to_s
      context.request.path = new_path
    end
    
    super
  end
end

module Sswws
  # options ...
  handlers = [
    HTTP::LogHandler.new, 
    HTTP::ErrorHandler.new, 
    IndexFileHandler.new(@@dir, directory_listing: false)
  ]
  server = HTTP::Server.new(handlers)
  # listen ...
end
