It's usual to have a static page even in a complex web application, like an "About" or "Contact us" section of a frontend site.
In Symfony, you'll usually want to fill a block of an outer base or layout Twig view with a static content.
It's possible to do so without writing a dedicated controller by handling the request to the built-in
TemplateController with this route:
Just add it to your
routing.yml and place the
.html.twig file under the correct path. That's it!
