This chapter tells about the Plesk extension structure and the tools
that Plesk provides for extensions development and management.
How to Create and Install Extensions
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.
Extensions Management Utility
The 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.
API Stubs
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.
Extensions Reference
The complete list of Plesk API tools that an extension can use can be
found in the Reference
document.
