File bootstrap.php loads Nette Framework and all libraries that we depend on:
require __DIR__ . '/../vendor/autoload.php';Class Configurator creates so called DI container and handles application initialization.
$configurator = new Nette\Configurator;Activates Tracy in strict mode:
//$configurator->setDebugMode(true);
$configurator->enableTracy(__DIR__ . '/../log');Setup directory for temporary files
$configurator->setTempDirectory(__DIR__ . '/../temp');Activate autoloading, that will automatically load all the files with our classes:
$configurator->createRobotLoader()
->addDirectory(__DIR__)
->addDirectory(__DIR__ . '/../vendor/others')
->register();And according to the configuration files it generates a DI container. Everything else depends on it.
We will return this DI Container as a result of calling app/boostrap.php
$configurator->addConfig(__DIR__ . '/config/config.neon');
$configurator->addConfig(__DIR__ . '/config/config.local.neon');
return $configurator->createContainer();and we will store it as local variable in www/index.php and run the application:
$container = require __DIR__ . '/../app/bootstrap.php';
$container->getService('application')->run();That's it.
