Lazy loading for [PSR-15 middleware and request handlers](https://www.php-fig.org/psr/psr-15/) that supports "just in time" instantiation using a [PSR-11](https://www.php-fig.org/psr/psr-11/) [container](https://packagist.org/providers/psr/container-implementation).

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

[](#installation)

The best way to install and use this package is with [composer](http://getcomposer.org/):

```
composer require northwoods/lazy-middleware
```

Usage
-----

[](#usage)

This package contains two factories: one for request handlers and one for middleware.

### LazyHandlerFactory::defer($handler)

[](#lazyhandlerfactorydeferhandler)

Create a new lazy handler.

The `$handler` identifier is *not* required to be a class name. Any string that refers to a container identifier can be used.

```
use Northwoods\Middleware\LazyHandlerFactory;

/** @var ContainerInterface */
$container = /* any container */;

$lazyHandler = new LazyHandlerFactory($container);

/** @var \Psr\Http\Server\RequestHandlerInterface */
$handler = $lazyHandler->defer(Acme\FooHandler::class);
```

### LazyMiddlewareFactory::defer($middleware)

[](#lazymiddlewarefactorydefermiddleware)

Create a new lazy middleware.

The `$middleware` identifier is *not* required to be a class name. Any string that refers to a container identifier can be used.

```
use Northwoods\Middleware\LazyMiddlewareFactory;

/** @var ContainerInterface */
$container = /* any container */;

$lazyMiddleware = new LazyMiddlewareFactory($container);

/** @var \Psr\Http\Server\MiddlewareInterface */
$middleware = $lazyMiddleware->defer(Acme\BarMiddleware::class);
```
