How to make breadcrumbs in Symfony 4.*?

Question

symfony

I find the WhiteOctober bundle, but it is for Symfony 2, although the authors write that it will also work for the versions above. Are there modern solutions for the latest versions of the framework?

Answer 1

Breadcrumbs are the frontend.
Symfony is an HTTP framework and a set of backend components.
The question was posed incorrectly.
I will assume that you are using twig. It is worth applying template inheritance and making a block with breadcrumbs, which you will override in child templates.
