Is it possible to somehow tag services through the implements interface?

Question

symfony

Hello everyone,

at the moment I'm tagging services, like this:

services.yaml:

MyNamespace\Service\MyService:
  autowire: true
  tags:
    - {name: app.my_tag}

Is it possible to do this somehow when creating a class (Service)?

For example:

class MyClass implements MyInterfaceForTagging{
}

Yes, starting from version 3.3, examples are in the documentation . In your case it will be:

# app/config/services.yml
services:
    _instanceof:
        MyNamespace\Service\MyInterfaceForTagging:
            tags: ['app.my_tag']

Also, starting with version 5.3, which will be released one of these days, it will be possible to use attributes from PHP8 for the same purpose, blog article about this.
