Babel presets are collections of plugins, nothing more

NoteFebruary 2, 20161 min read

A preset is a named list of plugins, which is why babel-preset-es2015 transpiles more than you need and stage-0 enables proposals that may never ship. Neither is a…

Upgrading a production application to PHP 7

Deep diveFebruary 2, 201614 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.

Model events fire on the model, not on the query builder

NoteFebruary 2, 20161 min read

Eloquent fires saving, created, deleted and the rest when a model instance is saved. A mass update or delete goes straight to the query builder and fires nothing…

NoteJanuary 22, 20161 min read

NoteJanuary 20, 20162 min read

Writing import and export does not mean the browser is loading modules. Babel rewrites both into CommonJS, webpack resolves them at build time, and what ships is one…

strict_types applies to the calls a file makes, not the calls it receives

NoteJanuary 19, 20161 min read

The rule reads backwards from how everyone assumes it works. declare(strict_types=1) governs the calls made from that file, not the calls made into the functions declared in it.…

list() is a language construct and never was a function

NoteJanuary 14, 20161 min read

list() looks like a function call and behaves like an assignment target, which is why it can appear on the left of = and why it cannot be…
