refactoring

  • A default export makes a rename silent

    Note2 min read

    A default export has no name at the boundary, so the importing file invents one. Rename the thing being exported and every import keeps working under the old…

  • Upgrading a production application to PHP 7

    Deep dive14 min read

    Twice the throughput and half the memory, for a migration that is mostly deletions — plus the four behaviour changes nobody puts in the upgrade notes.

  • Implicit route model binding removes the find()

    Note2 min read

    Every controller method that takes an id begins the same way: find the record, check it exists, abort with a 404. Multiply that by every route and it…

  • Return types make a refactor fail at the boundary

    Note1 min read

    A docblock @return is a comment; the engine never reads it, so a method that starts returning null on a Tuesday fails somewhere else on a Thursday. A…

  • intdiv() says what the floor division meant

  • DatePeriod iterates a date range without a loop counter

    Note2 min read

    Walking every day between two dates is usually a while loop with a manual increment and an off-by-one at one end. DatePeriod is an iterator over a start,…

  • Utils classes are where responsibilities go to hide

    Note2 min read

    A class named Utils, Helpers or Common has no definition, so nothing can be excluded from it. It grows monotonically, it is imported everywhere, and it ends up…

  • Migrating PSR-0 to PSR-4 removes a directory level

    Note1 min read

    PSR-0 mapped the entire namespace onto the path, so AppReportBuilder had to live at src/App/Report/Builder.php — the vendor and package name repeated inside a directory that was already…

  • Restructuring an application for Laravel 5

    Deep dive10 min read

    4.2 to 5.0 is not an upgrade, it is a relocation. Moving an application through it in an order that keeps it booting at every step.
