Workflow Canvas
Overview
The Workflow Canvas is a visual jsPlumb-based interface for designing learning journeys, managing system functions, and building content workflows.

BPMN Workflow Designer
The Workflow Designer at /admin/workflow-designer.php provides a full BPMN-compatible visual process designer:
- Node types: Start, End, Task, Decision (Gateway), Timer, Webhook, Notification
- Drag-and-drop connections between nodes
- Export/import workflow definitions
- Live instance monitoring at
/admin/workflow-instances.php - Process monitoring and control at
/admin/workflow-monitor.php - Dead Letter Queue at
/admin/workflow-dlq.php
Timer Node
The Timer node pauses a workflow execution for a defined duration before continuing. Use cases:
- Delayed notifications (e.g. “Send reminder 3 days after enrolment”)
- Spaced learning sequences
- SLA escalation after timeout
Timer nodes are processed by the workflow_timers cron job (runs every minute).
Meeting Canvas
The Meetings canvas (/organisation/workflow_meetings.php?ref=…) requires an organisation reference and provides:
| Button | Action |
|---|---|
| Create | Create a new meeting |
| Manage | Edit meeting details |
| Attendees | Manage who is invited |
| Minutes | Record meeting minutes |
| Actions | Track action items |
| Report | View meeting report |
| Export | Export meeting data |
| Delete | Delete a meeting |
Mobile Tile View
All 19 canvases render a mobile tile view on screens below 768px. Tiles are grouped by functional area and are touch-friendly. Groups are defined in the canvas PHP function (e.g. “Users”, “Database”, “Security”).
