Libraries

Overview

The Magento software can use the following types of libraries:

• Magento PHP libraries, which are discussed in the next section.

• Magento UI libraries, which are located in the lib/web directory.

  For more information, see library documentation on GitHub and View Library.

• Third-party libraries. These libraries include all PHP code (including the Zend libraries).

  Third-party libraries are organized by vendor to be PSR-0 compliant.

Magento PHP libraries

Magento PHP libraries include code that is designed to be independent libraries of code useful to a Magento application. Each library has minimal dependencies on any other library.

For example:

• Magento\Framework\Filesystem has PHP libraries for file system operations such as read, write, directory listing, and so on. We provide drivers for file, HTTP, HTTPS, and Zlib.

• Magento\Framework\App is a special PHP library that is aware of Magento as an application. It represents a greater level of abstraction and provides the following:

  • Application areas
  • Routing requests
  • Application state
