phpdot/container-swoole
=======================

[](#phpdotcontainer-swoole)

Swoole adapter for [phpdot/container](https://github.com/phpdot/container).

Each Swoole coroutine gets its own isolated service scope via `Coroutine::getContext()`. When the coroutine exits, Swoole destroys the context automatically — no manual cleanup required.

```

**Singleton** services resolve once and are shared across all coroutines in the worker.

**Scoped** services resolve once per coroutine and are stored in `Swoole\Coroutine::getContext()`. When the coroutine finishes, Swoole's runtime destroys the context and all scoped instances are garbage collected.

**Outside a coroutine** (CLI bootstrap, `onStart` callback), the provider falls back to an in-memory `ArrayContext`.

Server Example
--------------

[](#server-example)

```
use Swoole\Http\Server;
use PHPdot\Container\ContainerBuilder;
use PHPdot\Container\Swoole\SwooleContextProvider;
use function PHPdot\Container\singleton;
use function PHPdot\Container\scoped;

$container = (new ContainerBuilder())
    ->withContextProvider(new SwooleContextProvider())
    ->addDefinitions([
        Config::class  => singleton(),
        Session::class => scoped(fn($c) => Session::fromRequest($c->get(Request::class))),
    ])
    ->build();

$server = new Server('0.0.0.0', 8080);

$server->on('request', function ($req, $res) use ($container) {
    // Each request runs in its own coroutine.
    // Scoped services are fresh. Singletons are shared.
    $session = $container->get(Session::class);

    $res->end('Hello ' . $session->user());
    // Coroutine ends here — scoped instances destroyed automatically.
});

$server->start();
```

Request dispatching
-------------------

[](#request-dispatching)

`ContainerDispatcher` is a PSR-15 handler that resolves your real handler from the container **on every request** — inside the worker, after the fork. Serve it instead of the handler itself so the request path loads lazily (which keeps it hot-reloadable) and scoped services isolate per coroutine:

```
use PHPdot\Container\Swoole\ContainerDispatcher;

// $container built as above; App\Handler is your PSR-15 entry point.
$dispatcher = new ContainerDispatcher($container, App\Handler::class);

// Hand $dispatcher to your PSR-15 server (e.g. phpdot/server-swoole's serve()).
// On each request it calls $container->get(App\Handler::class) — resolving,
// and loading, in the worker.
```

If the configured id doesn't resolve to a `Psr\Http\Server\RequestHandlerInterface`, it throws — a fast failure for a misconfigured handler id.

      Loading Testing
-------

[](#testing)

The package is standalone-testable (requires ext-swoole):

```
composer install
composer test        # PHPUnit
composer analyse     # PHPStan, level max + strict rules
composer cs-check    # PHP-CS-Fixer
composer check       # All three
```
