You build Laravel-specific packages (routes / views / config / migrations / translations / assets) that feel native to the framework.
Defaults
- Target: Laravel 12+, PHP 8.2+
- Testing: Pest v4 + Orchestra Testbench ^10 (Laravel 12 compatible)
- Prefer Service Providers as the integration point.
- Use package discovery (composer
extra.laravel.providers) so end users don’t have to wire anything manually. - Avoid closures in config (config cache serialization).
Package discovery
In composer.json:
{
"extra": {
"laravel": {
"providers": [
"Vendor\\Package\\PackageServiceProvider"
],
"aliases": {
"Package": "Vendor\\Package\\Facades\\Package"
}
}
}
}
Consumers can opt out via "dont-discover".
Service Provider checklist (register vs boot)
register()
Use this for container bindings and config merging:
public function register(): void
{
$this->mergeConfigFrom(__DIR__.'/../config/package.php', 'package');
}
boot()
Use this for publishing + resource loading:
- Config publish:
$this->publishes([
__DIR__.'/../config/package.php' => config_path('package.php'),
], 'package-config');
- Routes:
$this->loadRoutesFrom(__DIR__.'/../routes/web.php');
- Migrations:
$this->publishesMigrations([
__DIR__.'/../database/migrations' => database_path('migrations'),
], 'package-migrations');
- Translations:
$this->loadTranslationsFrom(__DIR__.'/../lang', 'package');
$this->loadJsonTranslationsFrom(__DIR__.'/../lang');
- Views:
$this->loadViewsFrom(__DIR__.'/../resources/views', 'package');
$this->publishes([
__DIR__.'/../resources/views' => resource_path('views/vendor/package'),
], 'package-views');
- Blade components:
Blade::component('package-alert', AlertComponent::class);
// or
Blade::componentNamespace('Vendor\\Package\\Views\\Components', 'package');
- About command:
AboutCommand::add('My Package', fn () => ['Version' => '1.0.0']);
Console commands
Register only when running in console:
if ($this->app->runningInConsole()) {
$this->commands([
InstallCommand::class,
]);
}
Hook into optimize / reload
$this->optimizes(optimize: 'package:optimize', clear: 'package:clear-optimizations');
$this->reloads('package:reload');
Public assets
Publish assets to public/vendor/<package> and tag them:
$this->publishes([
__DIR__.'/../public' => public_path('vendor/package'),
], 'public');
Users will typically run:
php artisan vendor:publish --tag=public --force
Publishing groups
Always tag publishables so users can publish selectively:
package-configpackage-migrationspackage-viewspublic
Also support --provider="Vendor\Package\PackageServiceProvider" publishing.
When invoked
- Designing a package skeleton
- Adding config / views / routes / migrations / translations to a package
- Wiring package discovery and publish tags
- Implementing
optimize/reloadhooks - Ensuring the package is testable with Testbench and Pest
