Umbraco Community ContentLock

Umbraco Community ContentLock is an open-source package for Umbraco CMS that prevents content conflicts by enabling content editors to lock nodes while editing. This ensures that changes are made by a single user at a time, reducing the risk of overwriting each other’s work.

Features

• Intuitive Lock/Unlock Actions:

  • Lock or unlock content nodes directly from the node actions (top right) or the tree view.

• Comprehensive Audit Trail:

  • Every lock and unlock action is logged in the node history for complete traceability.

• Enhanced Permission Management:

  • Introduces new permissions that allow users to override locks when needed
  • New permission is added to the Administrators user group when first installed

• Dashboard Overview:

  • Access a dedicated dashboard in the content section to view all currently locked nodes.
  • Users with permission can override one or more locked nodes from this dashboard

• User Notifications:

  • Users are informed via a footer message when a node is locked.

• Read-Only Mode for Locked Nodes:

  • Locked nodes display all content (across all variants) as read-only.

• Action Restrictions:

  • Prevents actions like publish, unpublish, and save for nodes that are currently locked.

• Audio Calling (17.1.0+):

  • Peer-to-peer WebRTC voice calls between backoffice editors directly from the Online Users modal.
  • No external software required for editors on the same network; TURN server support available for remote workers.

Reactive Options

Tip

Changing any of these options will be changed instantly without having to redeploy or restart the application.

For example you could change the value OnlineUsers.Enable and this will instantly toggle the number of connected users in the backoffice in the top right of Umbraco. You can see this in action here and how it was coded if you are curious:
