Workflow Operations

This final chapter covers fundamental workflow operations and critical usage considerations.

Core Operations​

Workflow Operation

The workflow canvas features essential controls organized into distinct functional areas:

Top Toolbar Functions​

Left to right:

  1. Undo: Reverts the last canvas action
  2. Redo: Restores the last undone operation
  3. Import: Loads workflows from external .json files
  4. Export: Saves current workflow to .json format
    ⚠️ Excludes sensitive credentials (e.g., LLM API keys)
  5. Refresh: Reloads canvas
    ⚡ resets workflow to pre-execution state without interrupting execution
  6. Fullscreen: Toggles full-screen display
  7. Chatflow: Shows/Hides the Chatflow panel
  8. Run: Executes the current workflow
  9. Debug: Runs workflow in debug mode
  10. Save: Persists workflow modifications to storage
  11. Clear: Resets canvas (removes all nodes)
    ⏹️ During execution, this becomes a Stop button to terminate workflow after current node completion.
IMPORTANT

• Undo/Redo history clears upon page refresh or navigation
• While auto-save functions periodically, manual saving is recommended
• Nodes default to 1-hour timeout
• Stop only interrupts after current node completion
• Always test workflows before execution to prevent infinite loops

Canvas Navigation Controls​

Bottom-left:

  • Zoom In: Enlarges view (+)
  • Zoom Out: Reduces view (-)
  • Reset View: Restores default zoom + centers workflow
  • Lock Toggle:
    🔓 Unlocked: Enables individual node movement
    🔒 Locked: Moves entire workflow during drag

Bottom-right:

  • Minimap: Workflow overview with viewport indicator

Debug Mode​

Workflow Debug

Debug mode functions similarly to code compilers. You can temporarily pause workflow execution using breakpoints to inspect variable values and compare them against initial states.

Key Features:​

  1. Breakpoint Setup
    • Available on all nodes except Start node
    • Click Debug button in node config's Output section
    • Active breakpoints show 🔴 icon next to node name

Debug Walkthrough​

Consider a workflow with two Code nodes managing three variables:
number_1, number_2, and sum

Node 1: Executes sum = number_1 + number_2
Node 2: Prints sum value

Debug Process:

  1. Set breakpoint on Node 2
  2. Run debug mode
  3. Observe Global Variables:
    • Current values: number_1=1, number_2=2, sum=3
    • Initial values: 1, 2, 0
  4. Continue execution → Node 2 prints 3
  5. Advanced: Force-change sum to 4 during debug → Final output becomes 4
