Create site template with PowerShell

Question

I would like to save a few SharePoint Online sites as template for future use with PowerShell. How can I do this? I found code snippets for 2013 but they do not seem to work, I'm missing methods, cannot retrieve the web object (no Get-SPWeb), thus no .SaveAsTemplate. What are my options? I have 100+ different sites to save.

Update: All my different sites that I want to make template of, are under a site collection. This is how far I am with the PnP Powershell:

$WebURL = "myroot"
Connect-PnPOnline –Url $WebURL -Credentials $credential
foreach ($web in Get-PnPSubWebs -Recurse) {
$url = $web.url
Connect-PnPOnline –Url $web.url –Credentials $credential
$filename = $url -replace $WebURL, "" -replace "/", "_" -replace ":", "|"
$filename += ".xml"
$path = "C:\Temp\$filename"
Get-PnPProvisioningTemplate -Force -Out $path -PersistBrandingFiles -PersistPublishingFiles
}

I get the templates, I can also use them, but the web parts are missing (xml view web parts, content query web parts)

Answer 1

Take a look at the PnP PowerShell, namely the Get-PnPProvisioningTemplate, although I have a feeling it doesn't support SPWebs (although documentation talks of "webs").

So something like:

Connect-PnPOnline -Url "https://contoso.sharepoint.com/sites/publishing" -UseWebLogin

Get-PnPProvisioningTemplate -Out "C:\Path\to\template.xml" -PersistBrandingFiles -PersistPublishingFiles;

Answer 2

Site Provisioning with PnP PowerShell is good choice :

Get-PnPProvisioningTemplate -Out C:\temp\template.pnp -PersistBrandingFiles 
New-PnPTenantSite -Url 'https://tenant.sharepoint.com/sites/pnptempate' -Title 'New Site Collection' -Owner '[email protected]'
Connect-PnPOnline 'https://tenant.sharepoint.com/sites/pnptempate'
Apply-PnPProvisioningTemplate -Path C:\temp\template.pnp

Another approach you can use CSOM to meet your requirement .

Save Site as Template" using JSOM or CSOM
