Tips and Tricks

Pre-install required modules for Update-ModuleManifest to work

Add build number to ModuleVersion in module manifest

Update-ModuleManifest mangles nicely formatted module manifest

Test against the module instead of the *.ps1 files

Ways to load a module

Load from well-known location

Import-Module

Load from arbitrary location

Import-Module -Name .\MyModule\MyModule.psd1

Loading from location of source files

$Env:PSModulePath = "~\MyModules;$Env:PSModulePath"

–

Private module repository

Some code must remain private

Use any NuGet feed to host modules

Supported in many commercial products

Create your own feed using NuGet.Server from .NET Foundation

–

Prerelease versions

Module manifest can contain a prerelease tag :

@{
  ModuleVersion = '2.0.0'
  #...
  PrivateData = @{
    PSData = @{
      Prerelease = '-alpha'
    }
  }
}

This can be used when working with modules:

Find-Module -Name GoCD -AllowPrerelease
Install-Module -Name GoCD -AllowPrerelease

–

Prerelease versions

ModuleVersion usually follows SemVer

ModuleVersion may be MAJOR.MINOR.PATCH.BUILD

RequiredModules must follow SemVer like MAJOR.MINOR.PATCH

RequiredModules does not allow prerelease tag

Try to avoid prerelease tags
