Tip: drag this floating card to move around. Your position is saved locally.

Visiting /playground/goofy extracts "goofy" as urlEntry, passes it into the controller, and renders the template that shows Hello World, from 'word'.

Hello World, from goofy!

🔧 Page Mechanics

This page is powered by a Phoenix route and controller:

Route:
  get "/playground/:urlEntry", InputANDUrlController, :showFromUrl

Controller:
  def showFromUrl(conn, %{"urlEntry" => urlEntry}) do
    render(conn, :showFromUrl, urlEntry: urlEntry)
  end

Try replacing the word "goofy" with another word in the URL.
