In which template file is a node title supposed to be?

Question

I have to add a Title field to each content type to ensure a title appears on the node view.

This makes me wonder: Maybe I'm missing the title variable in my implementation of page.twig.html or something, but I don't see a title variable anywhere in the default page.html.twig.

1. In which template should my title variable be displaying?
2. What should the code in the template look like to display the title?

Answer 1

Page title is now a block

The page title is now provided by a block so it can be easily moved without editing the page template.

The markup for the page title can be edited in page-title.html.twig, and template_preprocess_page_title() can be used in conjunction with the template
