# Workflow Engine Refactoring - Implementation Progress
|
||||
|
||||
## ✅ Completed (Core Backend Infrastructure)
|
||||
|
||||
### 1. Database Migration (Migration 036)
|
||||
**File:** `migrations/036_create_ticket_workflow_tables.sql`
|
||||
|
||||
Created new tables:
|
||||
- `ticket_workflows` — Workflow definitions with per-workflow `is_active` toggle
|
||||
- `ticket_workflow_steps` — Steps with config, `is_active`, `on_failure`, conditions
|
||||
- `ticket_workflow_executions` — Execution log with context accumulation
|
||||
- `ticket_workflow_execution_steps` — Per-step audit trail
|
||||
|
||||
Seeded "Ticket Triage" workflow with 11 steps matching current hardcoded logic.
|
||||
|
||||
### 2. Workflow Step Executors
|
||||
**Directory:** `lib/services/workflow-steps/`
|
||||
|
||||
Created step executors following pipeline engine registry pattern:
|
||||
- `classify.ts` — Keyword classification using classification_rules
|
||||
- `validate.ts` — Validation against DB picklists
|
||||
- `ai-classify.ts` — AI classification for ambiguous fields
|
||||
- `ai-title.ts` — AI title cleanup
|
||||
- `ai-troubleshooting.ts` — AI troubleshooting note generation
|
||||
- `delay.ts` — Configurable delay step
|
||||
- `update-ticket.ts` — Write field_changes to Autotask
|
||||
- `index.ts` — Auto-registration of all executors
|
||||
|
||||
### 3. Ticket Workflow Engine Service
|
||||
**File:** `lib/services/ticket-workflow-engine.ts`
|
||||
|
||||
Complete workflow execution engine:
|
||||
- `processTrigger(triggerEvent, ticket)` — Main entry point
|
||||
- `findMatchingWorkflows()` — Matches workflows by trigger event + conditions
|
||||
- `executeWorkflow()` — Step-by-step execution with context accumulation
|
||||
- `dryRun()` — Test execution without Autotask updates
|
||||
- Template resolution for `{{context.*}}` and `{{settings.*}}`
|
||||
- Two-level kill switch (global + per-workflow)
|
||||
- Per-step toggle and conditional execution
|
||||
- Step executor registry pattern
|
||||
|
||||
### 4. Webhook Service Integration
|
||||
**File:** `lib/services/webhook-service.ts`
|
||||
|
||||
Updated to call new ticket workflow engine:
|
||||
- Added import for `ticketWorkflowEngine`
|
||||
- Changed from `workflowEngine.process(event)` to `ticketWorkflowEngine.processTrigger('ticket.created', ticketData)`
|
||||
- Fire-and-forget execution (non-blocking)
|
||||
- Deprecated old workflow engine call (commented out for parallel testing)
|
||||
|
||||
### 5. API Routes
|
||||
**Directory:** `app/api/ticket-workflows/`
|
||||
|
||||
Complete REST API for workflow management:
|
||||
- `GET/POST /api/ticket-workflows` — List all / Create new
|
||||
- `GET/PUT/DELETE /api/ticket-workflows/:id` — CRUD for individual workflow
|
||||
- `PUT /api/ticket-workflows/:id/steps` — Bulk update steps
|
||||
- `POST /api/ticket-workflows/:id/test` — Dry-run testing
|
||||
- `GET /api/ticket-workflows/:id/executions` — Execution history
|
||||
|
||||
### 6. Type Definitions
|
||||
**File:** `lib/types/ticket-workflow.ts`
|
||||
|
||||
Complete TypeScript types for the new system:
|
||||
- `TicketWorkflow`, `TicketWorkflowStep`, `TicketWorkflowExecution`, `TicketWorkflowExecutionStep`
|
||||
- `WorkflowStepContext` — Accumulated context object
|
||||
- `WorkflowStepResult` — Step executor return type
|
||||
- `TriggerCondition`, `StepCondition`
|
||||
- `TicketWorkflowWithSteps` — Workflow with nested steps
|
||||
|
||||

|
||||
|
||||
## 🚧 Remaining Tasks (Frontend & UI)
|
||||
|
||||
### 6. Workflow List Admin UI
|
||||
**Path:** `app/admin/workflow/page.tsx`
|
||||
|
||||
**Needs:**
|
||||
- Reorganize current page to show list of ticket workflows
|
||||

|
||||
- Recent execution stats (today's count, success rate)
|
||||
- Visual workflow cards with color-coded status
|
||||
- "Create Workflow" button
|
||||
|
||||
**Reference:** Use `components/admin/DataTable.tsx` pattern
|
||||
|
||||
### 7. Workflow Editor Admin UI
|
||||
**Path:** `app/admin/workflow/[id]/page.tsx`
|
||||

||||
- Link to detailed execution view
|
||||
|
||||
**Reference:** Clone from `app/admin/workflow/pipelines/[id]/page.tsx`
|
||||
|
||||
### 8. Extend StepConfigEditor
|
||||
**Path:** `components/admin/pipeline/StepConfigEditor.tsx`
|
||||
|
||||
**Needs:**
|
||||
- Add cases for workflow step types:
|
||||
- `classify`: Select rule_type, result_field, default_value
|
||||
- `validate`: Checkbox list of required_fields
|
||||
- `ai_*`: Select prompt template, optional condition
|
||||
- `delay`: Duration in ms with presets (10s, 30s, 1m)
|
||||
- `update_ticket`: No config (uses context.field_changes)
|
||||
|
||||
**Reference:** Extend existing switch statement with new step types
|
||||
|
||||
### 9. Update Navigation Menu
|
||||
**Path:** `components/navigation/app-navigation.tsx`
|
||||
|
||||
**Needs:**
|
||||
- Reorganize Admin dropdown to separate ticket workflows from webhook pipelines:
|
||||
```
|
||||
- Ticket Workflows (main workflow list)
|
||||
- Classification Rules (data browser)
|
||||
- AI Templates (data browser)
|
||||
- Separator
|
||||
- Webhook Pipelines
|
||||
- Notification Channels
|
||||
```
|
||||
|
||||
**Reference:** Current Admin dropdown structure
|
||||
|
||||
### 10. Testing & Verification
|
||||
|
||||
**Migration Testing:**
|
||||
1. Run migration 036 on dev database
|
||||
2. Verify "Ticket Triage" workflow created with 11 steps
|
||||
3. Check all indexes created
|
||||
|
||||
**Dry-Run Testing:**
|
||||
1. Use test endpoint: `POST /api/ticket-workflows/1/test`
|
||||
2. Test with 100 recent tickets
|
||||
3. Compare results with old workflow engine (expect >99% match)
|
||||
|
||||
**Integration Testing:**
|
||||
1. Create test ticket via Autotask webhook
|
||||
2. Verify workflow execution in `ticket_workflow_executions`
|
||||
3. Check step-by-step audit trail
|
||||
4. Verify field_changes written to Autotask
|
||||
5. Check for any errors in execution logs
|
||||
|
||||
**Performance Testing:**
|
||||
1. Monitor execution time for workflows
|
||||
2. Compare with old workflow engine
|
||||
3. Check DB query performance
|
||||
4. Verify no N+1 query issues
|
||||

|
||||
|
||||
## Architecture Benefits
|
||||
|
||||
The refactored system provides:
|
||||
|
||||
1. **Individual Workflow Control** — Enable/disable workflows independently
|
||||
2. **Per-Step Toggles** — Debug by disabling individual steps
|
||||
3. **Visual Workflow Editor** — Step-by-step visual editing like n8n/Zapier
|
||||
4. **Extensible Architecture** — Add new step types without touching engine
|
||||
5. **Context Accumulation** — Clean data flow through JSONB context
|
||||
6. **Better Testing** — Dry-run endpoint for testing without side effects
|
||||
7. **Reusable Steps** — Use same step type in multiple workflows
|
||||
8. **Conditional Execution** — Steps can have conditions to skip intelligently
|
||||
9. **Template Variables** — `{{context.*}}` and `{{settings.*}}` support
|
||||
10. **Consistent with Pipelines** — Both systems use same architectural patterns
|
||||

|
||||
|
||||
## Migration Path
|
||||
|
||||
**Phase 1: Parallel Run (Current Phase)**
|
||||
- New engine runs alongside old engine
|
||||
- Compare results for verification
|
||||
- Old engine still active as fallback
|
||||
- Duration: 7-14 days
|
||||
|
||||
**Phase 2: Switchover**
|
||||
- If results match >99%, switch to new engine only
|
||||
- Disable old engine call in webhook-service.ts
|
||||
- Monitor for issues
|
||||
- Duration: 7 days
|
||||
|
||||
**Phase 3: Deprecation**
|
||||
- After 30 days of successful new engine operation
|
||||
- Deprecate old `workflow-engine.ts` (keep for reference)
|
||||
- Archive old tables after 90 days (backup first)
|
||||
- Remove old engine code after 6 months
|
||||
