README

A quick and dirty dispatch process using Haltorouter.

This featherweight stack uses Symfony's HttpFoundation Request & Response objects with Smrtr's Haltorouter object to enable you to start developing extremely quickly.

Installation

From your project root:

  1. Require spawn-point with composer. Add "smrtr/spawn-point": "~1.0" to the require section of your composer.json.
  2. Run composer update to download the spawn-point library.
  3. Run vendor/bin/spawn spawn to create the required project files.

Configuration

vHost

Apache2 vhost configuration must declare the rewrite engine to be on and the document root to be inside a directory called public inside your project root. See the following vhost for a project called Buzz located in /var/www/Buzz:

# Buzz
<VirtualHost *:80>
    ServerName buzz.local
    ServerAlias www.buzz.local
    ServerAlias private.buzz.local
    DocumentRoot "/var/www/Buzz/public"
    RewriteEngine on
    SetEnv APP_ENV "development"
    <Directory "/var/www/Buzz/public">
        DirectoryIndex index.php
        AllowOverride All
        Order allow,deny
        Satisfy Any
        Allow from all
        Require all granted
    </Directory>
</VirtualHost>

Hostgroups

Use app/config/hostgroups.ini to organize hostnames into groups. These hostgroups are used to match requests. See the following hostgroup configuration for example which creates two groups, 'Public' and 'Private':

[development]
Public[] = "buzz.local"
Public[] = "www.buzz.local"
Private[] = "private.buzz.local"

Routes

Use app/config/routes.ini to define your routes. These routes will be passed into a Smrtr\Haltorouter instance. Routes can be grouped by environment if you wish. See the following example which defines a route to the homepage across the development & production environments:

[bootstrap]
homepage.route = "/"
homepage.method = "GET"
homepage.hostgroup = "Public"
homepage.target = "\Buzz\HomepageController@homepage"

[development : bootstrap]

[production : bootstrap]

The 'target' of the route tells the application which class to load and which method to call.

PHP settings

You may specify php settings, much like you would in php.ini, in app/config/phpSettings.ini. This is a convenient way to define php settings at runtime without depending on the php settings of the environment.

Usage

To complete our example we need to implement the homepage controller which we defined in our routes config.

In src\Buzz\HomepageController.php:

<?php
namespace Buzz;
use Smrtr\SpawnPoint\AbstractController;

class HomepageController extends AbstractController
{
    public function homepage()
    {
        echo "hello world!";
    }
}

Request parameters

1. Add a parametrised route to your app/config/routes.ini:
user.route = "/user/[i:id]"
user.method = "GET"
user.hostgroup = "Public"
user.target = "\Buzz\UserController@user"
2. Retrieve the parameter from the request object in src/Buzz/UserController.php:
<?php
namespace Buzz;
use Smrtr\SpawnPoint\AbstractController;

class UserController extends AbstractController
{
    public function user()
    {
        $id = (int) $this->getRoutedParam('id');
    }
}
