Service Providers

Service providers are the central place to register services into the container. Every class your plugin needs — controllers, repositories, shortcodes, jobs — should be wired up through a provider.

Creating a provider

php nikogin make:provider OrderServiceProvider

// app/Providers/OrderServiceProvider.php
class OrderServiceProvider extends ServiceProvider
{
    public function priority(): int
    {
        return 10;
    }

    protected array $services = [
        OrderRepository::class,
        OrderController::class => [OrderRepository::class],
    ];
}

Services array syntax

Syntax	Behaviour
MyClass::class	Instantiated with no arguments
MyClass::class => []	Instantiated with no arguments (explicit)
MyClass::class => [Dep::class]	Instantiated with resolved dependency
MyClass::class => [DepA::class, DepB::class]	Multiple dependencies resolved in order

Priority

Lower numbers run first. Providers are sorted by priority() before register() is called.

public function priority(): int
{
    return 5; // runs before priority 10
}

Auto-discovery

ProviderManager scans app/Providers/*.php automatically — any class that extends Provider is registered. You do not need to list providers anywhere.

How ServiceProvider works internally

// ServiceProvider::register() resolves each entry:
Container::bind(MyClass::class, fn() => new MyClass(Container::get(Dep::class)));
Container::get(MyClass::class); // instantiates immediately

This means side-effects in the constructor (like add_action, add_shortcode) fire at plugins_loaded time.
