Create PowerShell Function for All App Types
A PowerShell with SharePoint tutorial
 In
earlier articles, we have been working with a function that
creates generic lists. With just a few changes, this function
can be used for creating all kinds of apps.
In the demo below, Peter Kalmström first explains how to
change the list function to a function for SharePoint document
libraries.
After that, Peter writes a general function that creates
any SharePoint apps: Create-MyApp. For that, he adds an
AppType parameter with the variable type Microsoft.SharePoint.Client.ListTemplateType
to the function.
function Create-MyApp([string] $ListName, [string] $ListURL,
[Microsoft.SharePoint.Client.ListTemplateType] $AppType){
if($ListURL -eq ""){
$ListURL =$ListName.Replace(" ","").ToLower()
}
Finally, Peter changes the list and library functions so
that they call the general app function when you run them.
That way he keeps dedicated functions for lists and libraries,
but any changes in the function parameters only need to
be made in the Create-MyApp function.
function Create-MyList([string] $ListName, [string] $ListURL){
Create-MyApp -ListName $ListName -ListURL $ListURL -AppType GenericList
}
function Create-MyLibrary([string] $ListName, [string] $ListURL){
Create-MyApp -ListName $ListName -ListURL $ListURL -AppType DocumentLibrary
}
When Peter runs these scripts he uses the array and the
forEach loop that he created in earlier demos, but you can
of course also try them with a simple function call. In
any case, the app type must be specified in the call, as
we are no longer doing it in the function.
foreach($Dep in $Departments){
Create-MyApp -ListName $Dep -AppType Tasks
}
