Introduction
This article describes how to install Lightning Tools Actions in SharePoint 2019 or SharePoint Subscription Edition so that you can create actions that run on one or more items in a modern SharePoint list. The ability to use Lightning Tools Actions in SharePoint server environments was added with version 3.8.0.0 in April 2025 (prior to that, it was only available for SharePoint Online).
Download and install
Download the latest version of Lightning Tools Actions from our Customer Download Center.
Unzip the downloaded Lightning Tools Actions zip file to one of your SharePoint servers, and navigate to the “SharePoint 2019 or SE” folder. Within this folder, you'll see the ListActions.sppkg file (SharePoint Framework app) and an executable file called LTDeploy.
Navigate to your SharePoint App Catalog. This is usually at a URL similar to https://[YOURDOMAIN]/Sites/appcatalog or https://[YOURDOMAIN]/Sites/apps - it depends how the app catalog was configured. You can also find this by going to your farm's Central Admin site and clicking on Apps in the left navigation menu.
Drag the ListActions.sppkg file into the app catalog (or click Upload). You should see a message that Lightning Tools Actions has deployed successfully with no errors.
Deploy the JavaScript files
Next, the JavaScript files used by Lightning Tools Actions must be uploaded to the Site Assets library of the web application containing your app catalog. We provide an application to do this: LTDeploy.
Run the LTDeploy application on one of your SharePoint servers. This application will copy the necessary resource files to a folder named LA in the Site Assets library of the selected web application/s in your SharePoint environment.
In the LTDeploy UI, select the Web Application/s that you wish to deploy to, and click Deploy.
The contents of the LA folder will be copied into the Site Assets library of your Web Application's root site collection. You may wish to check that library to ensure this has occurred.
Add Lightning Tools Actions to your sites
Lightning Tools Actions should be added as an app to a site by the site owner. Keep in mind that a user logged in as Farm Admin / System Account cannot install an app in SharePoint.
After adding the app to a site, you should see a Lightning Tools Actions option on the Command Bar of any SharePoint modern list (to which you have Full Control permission).
Updating Lightning Tools Actions
You can follow the same instructions to update Lightning Tools Actions when a new version is available. Note that you will also need to run the LTDeploy.exe application again, to update any of the JavaScript files that have been changed or added.
