Auto wires

PHP-DI will take all the definitions it can find and compile them. That means that definitions like autowired classes that are not listed in the configuration cannot be compiled since PHP-DI doesn't know about them: https://php-di.org/doc/performances.html#optimizing-for-compilation

./config/auto-wires.php allows you to list the auto wired files the container does not know about, These will then be used to compile the container, which in turn will give the app a performance boost.

config/auto-wires.php

return [
    SomeClass::class => autowire(),
    AnotherClass::class => autowire(),
];
