Stack/Builder is a small library that helps you construct a nested HttpKernelInterface decorator tree. It models it as a stack of middlewares. Example ------- [](#example) If you want to decorate a [silex](https://github.com/fabpot/Silex) app with session and cache middlewares, you'll have to do something like this: ``` use Symfony\Component\HttpKernel\HttpCache\Store; $app = new Silex\Application(); $app->get('/', function () { return 'Hello World!'; }); $app = new Stack\Session( new Symfony\Component\HttpKernel\HttpCache\HttpCache( $app, new Store(__DIR__.'/cache') ) ); ``` This can get quite annoying indeed. Stack/Builder simplifies that: ``` $stack = (new Stack\Builder()) ->push('Stack\Session') ->push('Symfony\Component\HttpKernel\HttpCache\HttpCache', new Store(__DIR__.'/cache')); $app = $stack->resolve($app); ``` As you can see, by arranging the layers as a stack, they become a lot easier to work with. In the front controller, you need to serve the request: ``` use Symfony\Component\HttpFoundation\Request; $request = Request::createFromGlobals(); $response = $app->handle($request)->send(); $app->terminate($request, $response); ``` Stack/Builder also supports pushing a `callable` on to the stack, for situations where instantiating middlewares might be more complicated. The `callable` should accept a `HttpKernelInterface` as the first argument and should also return a `HttpKernelInterface`. The example above could be rewritten as: ``` $stack = (new Stack\Builder()) ->push('Stack\Session') ->push(function ($app) { $cache = new HttpCache($app, new Store(__DIR__.'/cache')); return $cache; }) ; ``` Inspiration ----------- [](#inspiration) - [Rack::Builder](http://rack.rubyforge.org/doc/Rack/Builder.html) - [HttpKernel middlewares](https://igor.io/2013/02/02/http-kernel-middlewares.html) ### Health Score 50 — FairBetter than 96% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity67 Solid adoption and visibility Community39 Small or concentrated contributor base Maturity63 Established project with proven stability Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
