Resolve
=======

[](#resolve)

Resolve is an autowiring and dependency resolver trait able to call functions or methods or make new instances of classes with (or without) the aid of a PSR-11 compliant container.

Use Resolve in your own project or library when you would like to leverage dependency injection decoupled from a specific `ContainerInterface` implmentation.

Installation
------------

[](#installation)

```
composer require nimbly/resolve
```

Requirements
------------

[](#requirements)

- PHP >= 8.0

Container support
-----------------

[](#container-support)

Resolve can optionally be passed a PSR-11 Container instance but does not ship with an implementation.

You can try one of these:

- [php-di/php-di](https://github.com/PHP-DI/PHP-DI)
- [league/container](https://github.com/thephpleague/container)
- [aura/di](https://github.com/auraphp/Aura.Di)
- [nimbly/carton](https://github.com/nimbly/carton)

Usage
-----

[](#usage)

Add the `Resolve` trait to anything you would like to add dependency injection capabilities to.

```
class Dispatcher
{
    use Resolve;

    public function __construct(
        protected Router $router,
        protected ContainterInterface $container)
    {
    }

    public function dispatch(ServerRequestInterface $request): ResponseInterface
    {
        $route = $this->router->resolve($request);

        $handler = $this->makeCallable($route->getHandler());

        return $this->call(
            $handler,
            $this->container,
            [ServerRequestInterface::class => $request]
        );
    }
}
```

Make
----

[](#make)

The `make` method can instantiate any class you may need and resolve the constructor dependencies automatically from both the container instance (if one was provided) and the optional parameters you provide.

```
$instance = $this->make(
    FooHandler::class,
    $this->container,
    ["additional_parameter" => "Foo"]
);
```

Make a thing callable
---------------------

[](#make-a-thing-callable)

Often you would like to make something that represents a callable into an actual `callable` type. You can pass a string that represents a callable or an actual `callable` into the `makeCallable` method.

```
// An invokable class.
$invokable = $this->makeCallable(Foo::class, $this->container);
```

You can pass in a fully qualified class namespace, an `@` symbol, and the method name. For example:

```
// A class and method name string.
$instance_method = $this->makeCallable("\App\Http\Handlers\FooHandler@createNewFoo");
```

Call
----

[](#call)

The `call` method will call any `callable` you pass in, resolve the dependencies of that callable from both the container and the optional set of parameters passed, and invoke that `callable`.

If a dependency cannot be resolved from the container or optional parameters, Resolve will attempt to `make` one for you automatically.

If making the dependecy fails or is not possible, an exception will be thrown.

Callable types
--------------

[](#callable-types)

### Instance method

[](#instance-method)

```
$this->call(
	[new FooHandler, "findById"],
    $this->container,
	[
		ServerRequestInteface::class => $serverRequest,
		"id" => "3122accd-e640-4c4c-b299-ccad074cb077"
	]
);
```

### Static method

[](#static-method)

```
$this->call(
	[FooHandler::class, "findById"],
    $this->container,
	[
		ServerRequestInteface::class => $serverRequest,
		"id" => "3122accd-e640-4c4c-b299-ccad074cb077"
	]
);
```

### Invokable

[](#invokable)

```
$this->call(
	new FooHandler,
    $this->container,
	[
		ServerRequestInteface::class => $serverRequest,
		"id" => "3122accd-e640-4c4c-b299-ccad074cb077"
	]
);
```

### Function

[](#function)

```
$this->call(
	"\Handlers\Foo\findById",
    $this->container,
	[
		ServerRequestInteface::class => $serverRequest,
		"id" => "3122accd-e640-4c4c-b299-ccad074cb077"
	]
);
```
