  • An event-driven seam between two services

    Deep dive10 min read

  • Laravel 5.4 dropped the model events you were using

    Note2 min read

    5.4 removed the string-based model events fired through the event dispatcher — eloquent.saved: AppOrder and its relatives — in favour of an $dispatchesEvents map to real classes. The…

  • composer install –no-scripts on a machine you do not trust
