Apa iku service providers?

Question

Accepted Answer

**Service providers** iku panggonan pusat kanggo **bootstrap lan configure** aplikasi Laravel mu — ndaftar layanan ing container, binding interfaces menyang implementations, lan setup packages. Iku cara Laravel (lan packages) nyambung fungsionalitase ing startup.

## Struktur: register lan boot

```php
<?php
class AppServiceProvider extends ServiceProvider {
    public function register(): void {
        // BIND things into the container — runs FIRST, for all providers
        $this->app->bind(PaymentGateway::class, StripeGateway::class);
        $this->app->singleton(Reporter::class, fn() => new Reporter(config('reporting')));
    }

public function boot(): void {
        // BOOTSTRAP — runs AFTER all providers are registered
        // (everything is available; use for view composers, observers, macros, etc.)
        View::composer('dashboard', DashboardComposer::class);
        Model::preventLazyLoading();
    }
}
```

Saben provider nduweni rong methods: **`register()`** (bind services menyang container — runs pisanan, dadi aja nggunakake service liya nang kene) lan **`boot()`** (runs sawise kabeh providers registered, dadi kabeh ana — kanggo setup sing bergantung ing service liya).

## Apa providers digunakake kanggo

```text
✓ Binding interfaces to implementations in the container
✓ Registering singletons and configuring services
✓ Bootstrapping packages (their service providers register their features)
✓ Registering event listeners, observers, view composers, route/macro setup
✓ Loading config, routes, migrations, or views (especially for packages)
```

## Ndaftar providers

```php
// providers are listed in config/app.php (or bootstrap/providers.php in newer Laravel)
// generate one: php artisan make:provider PaymentServiceProvider
```

## Paano packages nggunakake iku

```text
A Laravel package ships a service provider that registers ITS services, routes,
config, and views into your app when installed — this is how packages "plug in".
```

## Mengapa iku penting

Service providers iku konsep penting Laravel — iku mekanisme pusat kanggo **bootstrapping lan configuring** aplikasi lan packages-ne, dadi ngerteni iku berharga kanggo organisir setup aplikasi lan kanggo ngerti paano Laravel lan ekosistem-ne berjalan.

Providers iku papan nang mana sampeyan ndaftar services menyang container (binding interfaces menyang implementations, configuring singletons), setup perilaku application-wide (event listeners, observers, view composers), lan papan nang mana framework lan saben package nyambung fungsionalitase ing startup.

Ngerteni **`register()` vs `boot()` distinction** (register kanggo binding services — runs pisanan; boot kanggo setup sing bergantung ing service liya — runs sawise kabeh diregistrasi) iku kunci kanggo nggunakake providers kanthi bener lan ngindari ordering bugs.

Jinisine, service providers iku paano **packages integrate** karo aplikasi mu — package ndadel provider sing ndaftar services, routes, config, lan views-ne, sing iku fondasi saka extensibility Laravel.

Ngerteni apa providers kanggo, lifecycle register/boot, lan paano iku bootstrap code lan packages mu iku pengetahuan penting kanggo struktur application configuration kanthi bener, integrate lan build packages, lan ngerti paano Laravel assemble dhewe ing startup — nggawe iku topik sing meaningful kanggo development Laravel intermediate-to-advanced lan kanggo kerja karo package ecosystem saka framework.
