README

event-sourcing-phpstan-extension

"PHPStan that understands your aggregates and catches event sourcing mistakes before runtime."

Features

• Property initialization for aggregate roots and child aggregates, so PHPStan does not report false uninitialized property errors.
• Recording in apply methods is reported as an error, because recording events while replaying them leads to duplicated events.
