README

Middleware can either be:

• an instance of `Ds\Middleware\MiddlewareInterface

• Extend `Ds/Middleware/Middleware

• Closure with the following signature:

  function(ServerRequest $request, ResponseInterface $response, callable $next = null){

    //code before calling next middleware.
  
    if ($next){
       $next($request, $response)
    }
  
    //code after calling next middleware.
  
    return $response;
  

  }

Stacks

Stacks are named collections of middlewares

$stack = new Ds\Middleware\Stack();
$stack->withNamespace('My\Class\Namespace');

//The following with create a new stack called 'stackId'
//'MyClass::MyMethod' has been added to the following collection: 'stackName'
//'MyClass2::MyMethod2' has been added to both collections: 'stackName', 'altName'

$stack->withMiddleware('MyClass::MyMethod', 'stackId', ['stackName'])
$stack->withMiddleware('MyClass2::MyMethod2', 'stackId', ['stackName','altName'])

Pipe

Pipes execute Stacks and return a PSR ResponseInterface

$pipe = new Ds\Middleware\Pipe();
$pipe = $pipe->withContainer($container)

$middlewareQueue = $pipe->fromStack($stack, 'stackId', 'stackName');

//call using invoke
$response = $middlewareQueue($request, $response);

//call using method 'execute'
$response = $middlewareQueue->execute($reqest, $response);
