Customize SharePoint Online Site Template

 SharePoint Online Site Design (renamed as Site Template) and site scripts used to automate modern SharePoint sites provisioning with your own custom or pre-defined set of actions and configurations.



Site Template can be applied (Navigate to Site Collection -> Settings -> Apply a Site Template),


Once the user clicks to "Apply a Site Template", select a template that shows two options,

1. From Microsoft -> It shows the template from the lookbook (https://lookbook.microsoft.com/). Site Template appears differently as per Communication Site or Modern Teams Site Collection.

2. From your organization -> It shows all custom-designed Site Template.


Let's get started with customize Site Template,

Scenario

In an organization, when people want to apply department or business unit specific defined "Site Template" to newly created or existing Modern Site Collection, it assists to maintain the consistency across the site collection with respect to theme, schema, master data, association with hub sites as well as security. It's quite useful, you need to push the Site Collection level changes as Site Template to existing Site Collection with never version of Site Scripts & Site Template (which consists of a pre-defined set of activities and configurations).

For example, IT Department people create a new Site Collection for each and every project, Once it is created with OOTB templates like Communication or Teams Site Template, Customize designed Site Template can be applied to maintain consistency with the look and feel, schema, permission, etc. In the future, if you want to release new changes to the Site Template, the user can release a new version of the Site Template associated with scripts and make it available. It can be easily available to the site owners to apply or update the existing sites.


SharePoint online site Template is used to apply configurations or actions to existing modern sites, like,

  • Create additional list
  • Apply a theme
  • Join a hub site etc.

There are almost 300 actions or 100,000 characters that can be bumped into site scripts. A site design can be associate with one or more associated site scripts. Site Scripts are JSON files that contain the ordered list of actions that will apply the custom configurations (ex. creating a list, joining a hub site, etc.) onto the new or existing created site.

Generate Site Scripts

Site Scripts is a collection of actions and sub-actions such as creating a list, site column, content type, theme. Each action is specified as "Verb". Verb actions run in the order they specified or appear in JSON script. Check out the JSON Schema for all actions available.

Site Script sample can be downloaded from Github to re-use into your own scripts.

Below scripts have reference to create Site Column, Site Content-Type, SP List, Data Column Formation, and add navigation.

BASIC

where mittal1201 should be your domain name.

$sitescriptLocation="C:\Path\ProjectSiteScriptV1.json"
Get-Content $sitescriptLocation -Raw | Add-SPOSiteScript -Title "ProjectSiteScriptV1"
BASIC

After running the script, you get a result with script ID. Keep track of ID, it will be used to associate with Site Template.





Create Site Template

The Site Template appears in the drop-down list of choose designs while provisioning the Site Collection. It can run one or more site scripts.

Add-SPOSiteDesign -Title "Project Site TemplateV1"
-WebTemplate "68"
-SiteScripts "efc8a372-7da3-497d-b3a2-2ee64611e4a3"
-Description "Project Site TemplateV1 site template designed for IT department projects to create and maintain the consistency of project sites with common schema across all site Project Site Collections."

$spoadminSiteUrl = "https://mytenant-admin.sharepoint.com"
$cred = Get-Credential
Connect-SPOService $spoadminSiteUrl -Credential $cred
Get-SPOSiteDesign
Get-SPOSiteScript
BASIC

Currently, there is no manual option to delete existing Site Templates or Site Scripts. You need to execute the below scripts to delete it. Deletion of existing Site Template will not delete associated Site Scripts. Site Scripts need to delete separately.

$spoadminSiteUrl = "https://mytenant-admin.sharepoint.com"
$siteDesignId = "be42d063-f67b-4d35-88df-88db0a79a59e"
$siteScriptId = "5f99d2b8-c0f4-41e2-81c0-67bb5e3ba1bd"
$cred = Get-Credential
Connect-SPOService $spoadminSiteUrl -Credential $cred
Remove-SPOSiteDesign -Identity $siteDesignId
Remove-SPOSiteScript -Identity $siteScriptId
