Autowiring By Type and Name

Introduction

Since Symfony 4.2, services can now be bound by type and name.

Syntax

# config/services.yaml
services:
    _defaults:
        bind:
            # it works with scalar types too (string, int, array, etc.)
            string $adminEmail: '[email protected]'
 
            # but it's mostly used with classes
            Psr\Log\LoggerInterface $requestLogger: '@monolog.logger.request'
