WOW

• Super-fast
• http status code are important
• uses some DDD concept
• Super micro it is yocto
• it works :)

6 tweets framework

function form($d,$r){foreach(array_intersect_key((array)$r,(array)($c=is_object($d)?$d:new$d))as$a=>$v){$c->$a=$v;}return $c;}
class Is{var$r;function ok($o,$m){$e=[];foreach($o as$p=>$v)foreach($m[$p]as$a)if(!preg_match($this->r[$a]?:$a, $v))$e[$p]=$a;return$e;}}

Real Demo:

There's a running example in the ./Example/index.php file.

Install

1. first clone: git clone [email protected]:liuggio/sized140.git, and enter in the cd sized140
2. just run with php -S localhost:8080 Example/index.php

open your browser at localhost:8080

Components

1. Hub: executes the controller

Execute controller and find the best match injecting the $request

hub usage

class Controller{
   public function get($slug /*,$request*/) {
       return "[$slug]";
   }
}

$routes = [
    'GET /blog/(\w+)' => '\Sized140\Controller::get',   // will match this
    'POST /blog' => function($request) {echo "Hi mate";}
];

$output = hub('/blog/titleslug', $request=[], $routes, 'GET'); // [titleslug]

2.Form

Forming a DTO in a tweet:

It fills a DTO from a given request, Domain Driven Design Approved.

Form() usage

$httpRequest = array('who'=>'liuggio', 'something we don\'t need');

$kissCommandDTO = form('\sized140\KissCommandDTO', $httpRequest);

echo $kissCommandDTO->who; // liuggio

or given an already instantiated object:

$httpRequest = array('who'=>'liuggio', 'something we don\'t need');

$kissCommandDTO = new \sized140\KissCommandDTO();
$kissCommandDTO->who = 'nobody';

$kissCommandDTO = form($kissCommandDTO, $httpRequest);

echo $kissCommandDTO->who; // liuggio

3. Is->ok object validation

Validation in a tweet:

Given an object, Is->ok will check if all the proprieties respect the validation as regex on the mappings array

Is->ok() usage

// the object to validate:
class User
{
    public $name;
    public $email;
}

// The Object mapping
$userMapping = [
// property | assertion types
    'name'  => ['string', '/^[\S]{3,}$/'],
    'email' => ['email']
];

$alice =  new User();
$alice->name = 'Alice';
$alice->email = '[email protected]';

// init object
$is = new Is();
// register assertions
$is->r = [
    'string' => '/^[\S]+$/',
    'email' => '/^\S+@\S+\.\S+$/'
];

// Is the object OK?
$errors = $is->ok($alice, $userMapping);

count($errors) is 0 if there's no error;

4.Route Matcher

The route matcher in a tweet:

Given an array of routes, it find the one matching with the request.

Match usage

$routes = [
    '/users/(\w+)/blog/(\w+)' => '\Sized140\UserController::get', // class name or function
    '/admin/(\w+)' => function ($id) {echo $id;}
];

$output = match($_SERVER["PATH_INFO"], $routes); //$_SERVER["PATH_INFO"] = "/users/15/blog/38";

// $output is ['/users/(\w+)/blog/(\w+)', '\Sized140\UserController', [15,38]]
// var_dump(return call_user_func_array($output[1],$output[2]));

5.Template engine

Contribution provided by @claudio-dalicandro

The template Render in a tweet:

It replaces variables in a template.

Render usage

$template = "{the} {test}";
$dto      = new \StdClass();

$dto->the  = "Hello";
$dto->test = "World";

echo render($template, $dto); // "Hello World"

or simply use array:

$dto = array('the'=>'Hello', 'test'=>'world');

echo render($template, $dto); // "Hello World"

6.Emit the Event Dispatcher

The Object Oriented Event dispatcher in a tweet:

Emit usage

$emit = new Emit();
// Binding 1 event to 2 listeners
$emit->bind('FoodOrdered', function(){
        echo 'FOOD ORDERED...';
});
$emit->bind('FoodOrdered', function($e){
        echo $e->name;
});

$event = new FoodOrdered('Pizza');
// calling the event
$emit($event);
