Building Modules

A module groups a set of commands together, most often around a common system, service, or purpose. Modules were introduced with PowerShell 2.

A module written in PowerShell can contain functions, classes, enumerations, and DSC resources, and it may define aliases and include variables to include in the global scope.

There are several different common styles or layouts used when authoring modules. This chapter explores these different approaches, starting with the simplest.

This chapter explores the following topics:

  • Creating a module
  • Publishing a module
  • Multi-file module layout
