Hello there,

Sorry for taking so long to review this! 😬
If you're still eager to contribute, I required some minor changes.

Thanks a lot!

Hi @domino91, thanks for getting back on this.
Can you please fix CI (composer linter:fix) and add an integration test?
You could try to issue a GET request to /.well-known/mercure without any topic: it should respond with a 400 Bad Request and you're supposed to see CORS headers in the response.

Some LOC remain uncovered: https://app.codecov.io/gh/bpolaszek/freddie/pull/23/blob/src/Hub/Middleware/CorsMiddleware.php

Thanks!
