router.ex中的scope是什么意思，是新发明的宏吗？

Question

  scope "/", HelloWeb do
    pipe_through :browser

    get "/", PageController, :index
    get "/hello", HelloController, :index
  end

The scope is lowercase started, it is a variable or syntax keyword invented macro? How to understand it?

Answer 1

scope is indeed a macro, just like pipe_through , get , post etc, as you can see in the documentation.

Under the bonnet it creates the routes to dispatch a matching request to the correct controller action and it creates helper functions to generate links to these routes.

To understand it better, take a look at the documentation and/or the code .
