editing_presence 1.0.0-alpha1

First alpha release of Editing Presence. It shows who else is editing the same content, live, on the edit form. It is a soft lock: nobody is blocked, editors are just warned before they overwrite each other's changes.

Features

• A live "alice is also editing this content" notice at the top of edit forms, built on Drupal core HTMX (no custom polling JavaScript, Node.js or WebSocket server).
• Field-level presence: other editors see which field someone is working in, outlined with a badge and linked from the notice.
• The notice clears right away when an editor saves, leaves or closes the tab (sendBeacon). Otherwise the editor is dropped after a configurable timeout.
• Works with any content entity type (nodes by default).
• Settings page at Configuration » Content authoring » Editing Presence: tracked entity types, heartbeat interval (15 s) and presence timeout (90 s).
• Access aware: only users who can update an entity see or report presence on it, and a field is shown only to editors who can edit that field.
• POST-only, CSRF-protected endpoints. Stale rows are removed on cron and when an entity or user is deleted.
• Kernel and functional test coverage, plus GitLab CI.

Requirements

• Drupal 11.3 or later. No contributed modules needed.

Installation

composer require 'drupal/editing_presence:^1.0@alpha'
