**Magento\Framework\App** implements most of the Magento application framework.

Unlike other components of **Magento\Framework** that are generic libraries not specific to Magento application, the **Magento\Framework\App** is "aware of" Magento application intentionally.

The library implements a variety of features of the Magento application:

  • bootstrap and initialization parameters
  • error handling
  • entry point handlers (application scripts):
    • HTTP – the web-application entry point for serving pages of Storefront, Admin, etc
    • Static Resource – for retrieving and serving static content (CSS, JavaScript, images)
    • Cron – for launching cron jobs
  • Object manager, filesystem components (inheritors specific to Magento application)
  • Caching, cache types
  • Language packages, dictionaries
  • DB connection configuration and pool
  • Request dispatching, routing, front controller
  • Services for view layer
  • Application areas
