Display Builder Dev Tools

This module follows the Display Builder 1.0.x-dev branch and may break at any time when used with a different version.

Overview

Display Builder Dev Tools is a companion module for local development and debugging. It is not intended for production use — it exposes destructive bulk operations and raw internal state that would be inappropriate on a live site.

Admin actions

• Import / export instance sources — serialize a display_builder_instance source tree to YAML and restore it, useful for sharing or reproducing layouts across environments
• Delete instances — remove instances that are not managed by config (i.e. standalone runtime instances)
• Delete history — wipe all undo/redo revisions across every instance to free storage during heavy iteration
• Delete all presets — bulk-remove every saved preset

Debug API endpoints

Adds three read-only JSON endpoints on any instance for inspecting internal state:

• /admin/structure/display-builder/instance/{id}/state — current resolved source tree
• /admin/structure/display-builder/instance/{id}/index — the path index cache
• /admin/structure/display-builder/instance/{id}/structure — normalized flat structure maps
