PowerShellGet

PowerShellGet is a package management module for Windows PowerShell and PowerShell Core that enables discovery, installation, and publishing of PowerShell modules and scripts from the PowerShell Gallery and other repositories. It provides a set of cmdlets that integrate with the PackageManagement framework, allowing users to manage modules in a consistent way across platforms.

It was introduced to simplify sharing and reuse of PowerShell code and to provide a standard interface for accessing software packages in the PowerShell ecosystem. The primary repository is the PowerShell Gallery, which hosts scripts and modules. PowerShellGet relies on the NuGet provider and the PackageManagement infrastructure to download and install content, and it supports registering multiple repositories with Register-PSRepository.

Typical workflow includes registering PSGallery, searching for modules with Find-Module, installing with Install-Module, and updating with Update-Module. For scripts, there are Find-Script and Install-Script. Administrators can publish their work with Publish-Module or Publish-Script, once authenticated to the repository. On first use, prerequisites such as the NuGet provider may be installed automatically.

PowerShellGet supports per-user and all-user installations, versioning, and dependency handling. It is available as a separate module and can be updated independently from PowerShell itself. While focused on the PowerShell Gallery, it can work with other registered repositories and can be used in both Windows PowerShell and PowerShell Core environments.
