Over Laravel-spiekbriefje

Deze Laravel cheat sheet vat het framework-oppervlak samen dat je dagelijks gebruikt: Artisan CLI, routing, controllers, Eloquent ORM, de query builder, migraties en schema, Blade-templates, validatie, requests en responses, collections, auth en middleware, en helpers.

Laravel heeft een expressieve maar brede API — de exacte Eloquent-relatiesignatuur, een migratie-kolommodifier, een validatieregelnaam, een collection-methode — en elke rij hier toont de echte aanroep met een korte omschrijving, zodat de sheet leest als het framework in steno.

Hij is gratis en wordt volledig in je browser gerenderd. Filter elk snippet live met de zoekbox, spring tussen secties via de sticky inhoudsopgave, kopieer code met één klik en print de sheet als framework-naslagwerk terwijl je bouwt.

Hoe gebruik je Laravel-spiekbriefje

Blader door de twaalf secties, van Artisan CLI en Routing tot Eloquent ORM en Helpers & overig.
Zoek naar een term zoals migration, hasMany of validate om de sheet live te filteren.
Spring naar een sectie zoals Blade templates of Collections via de sticky zijbalk.
Klik op een snippet of het kopieerpictogram ervan om de PHP naar je project te kopiëren.
Print de sheet als offline Laravel-naslagwerk.
