I need to know, area wise config will load by application entry point files like /Magento/Framework/App/Http launch method.

But I'm not able to figure it out app/etc/di.xml config load.

File: vendor/magento/framework/App/ObjectManagerFactory.php

Line: 259 , method: _loadPrimaryConfig

Here the primary config (app/etc/di.xml) is loaded first time:


All another di.xml was loaded in the:

  1. For the developer mode: Magento\Framework\App\ObjectManager\Environment\Developer::configureObjectManager()
  2. For the production mode: Magento\Framework\App\ObjectManager\Environment\Compiled::configureObjectManager()

by calling the:


which loads instance of the Magento\Framework\App\ObjectManager\ConfigLoader and loads the config files in the load() method dynamically or from the cache (if enabled):

 * {inheritdoc}
public function load($area)
    $cacheId = $area . '::DiConfig';
    $data = $this->_cache->load($cacheId);

    if (!$data) {
        $data = $this->_getReader()->read($area);
        $this->_cache->save(serialize($data), $cacheId);
    } else {
        $data = unserialize($data);

    return $data;

Result in the debug looks like this:

result in the debug

Then the result merges in the Magento\Framework\ObjectManager\ObjectManager::configure() method with initial config (app/etc/di.xml). All data are stored in the config attribute ($this->_config) of the ObjectManager.
