How to Publish Your PowerShell Module to the PowerShell Gallery

Jana

Publishing your PowerShell modules to the PowerShell Gallery (PSGallery) is an excellent way to share your work with the community. Initially, I encountered issues when publishing because I was using PowerShell 5. Since these problems cost me quite some time, I decided to write this guide to help you avoid similar pitfalls. Make sure you’re running PowerShell 7.x or newer, and follow this straightforward guide to successfully publish your own modules.

I personally use the ISESteroids module, developed by Dr. Tobias Weltner, to create my modules, which significantly simplifies the process for me. You can try it out for a few days before purchasing a license, and more information is available at powershell.one.

Prerequisites

Ensure you have the following:

Step-by-Step Guide

Step 1: Create a Module Manifest

Start by creating a manifest file (.psd1). This file contains essential information about your module:

PowerShell
New-ModuleManifest -Path '.\MyModule\MyModule.psd1' -RootModule 'MyModule.psm1' -Author 'YourName' -Description 'Description of your module' -PowerShellVersion '5.1'

Make sure to properly specify:

  • ModuleVersion
  • Tags
  • ProjectUri
  • LicenseUri

Step 2: Test Your Module

Always test your module thoroughly before publishing:

PowerShell
Import-Module .\MyModule
Get-Command -Module MyModule
Test-ModuleManifest -Path '.\MyModule\MyModule.psd1'

Step 3: Publish Your Module

Publish using the following command:

PowerShell
Publish-Module -Path '.\MyModule' -NuGetApiKey 'YourAPIKey'

My Published Modules

I’ve published several modules to the PowerShell Gallery:

  • BlizzWoWRetailProfile (Latest Version: 3.2.1)
    Access character profiles including achievements, reputations, and PvP stats from World of Warcraft.
  • BlizzWoWRetailGameData (Latest Version: 3.5.1)
    Provides interaction with Blizzard’s World of Warcraft Game Data API.
  • BlizzMySQLHelper (Latest Version: 1.7.1)
    Helper functions for integrating Blizzard API data with MySQL.

Publishing these modules has taught me that the process is straightforward and highly rewarding. It’s fantastic to see your modules used and appreciated by others in the community.

Happy publishing!
