Plesk Extensions Basics
This chapter tells about the Plesk extension structure and the tools that Plesk provides for extensions development and management.
A ready for distribution extension is a ZIP archive which contains a specifically-organized directory structure and a file with meta information describing the software. The main steps of extension creation and installation are described in How to Create and Install Extensions.
extension command-line utility enables you to manage extensions
through the command-line interface, including installation or removing
of extensions, packing the source files of an extension into a ZIP
archive ready for distribution, and generating an extension template.
Learn more in Extensions Management Utility.
Plesk Extensions API stubs is a set of files with all classes definitions and methods prototypes, but without implementation of these methods. You can use API stubs for quicker development. Learn more in API Stubs.
The complete list of Plesk API tools that an extension can use can be found in the Reference document.
