Check Service Autowiring Using Console Command in Symfony 7

The Symfony framework provides numerous pre-built commands that allow the debugging of different parts of an application. Autowiring is a mechanism that automatically injects dependencies into the services, saving you from the hassle of manual configuration. This tutorial explains how to check service autowiring using console command in Symfony 7.

To get all classes and interfaces that you can use as type-hints for autowiring, use the debug:autowiring command without any additional arguments.

php bin/console debug:autowiring

Additionally, you can also provide an argument to filter the list of autowirable services:

php bin/console debug:autowiring serializer

Output example:
