    marginBottom: "6px",
    letterSpacing: "0.3px",
    lineHeight: 1.3,
    color: "#f1f5f9",
  }}
>
  {it.label}
</div>;
{
  truncatedSubtitle && (
    <small
      className="text-muted"
      style={{
        lineHeight: 1.5,
        fontSize: "14px",
        color: "#cbd5e1",
        fontWeight: 400,
        letterSpacing: "0.2px",
      }}
    >
      {truncatedSubtitle}
    </small>
  );
}

styles.css:

.palette-item {
  min-height: 120px; /* Up from 88px */
  font-size: 16px; /* Up from 15px */
  padding: 20px 22px; /* Up from 16px 18px */
  gap: 20px; /* Up from 16px */
}

.palette-item-icon {
  font-size: 88px; /* Doubled from 44px */
  width: 96px; /* Doubled from 48px */
  height: 96px; /* Doubled from 48px */
}

---

🎯 Feature 2: Proper Case Module Names

What Changed

Before:

• TwilioSendModule → Displayed as "TwilioSendModule"
• FacebookPagePostModule → "FacebookPagePostModule"
• RestGenericModule → "RestGenericModule"

After:

• TwilioSendModule → "Twilio Send Module"
• FacebookPagePostModule → "Facebook Page Post Module"
• RestGenericModule → "Rest Generic Module"

Implementation

execModuleCatalog.ts:

/**
 * Convert camelCase or PascalCase module name to Proper Case with spaces
 */
export function convertToProperCase(moduleName: string): string {
  // Remove "Module" suffix
  let name = moduleName.replace(/Module$/, "");

  // Insert spaces before capital letters
  name = name.replace(/([A-Z])/g, " $1").trim();

  // Capitalize first letter of each word
  name = name
    .split(" ")
    .map((word) => word.charAt(0).toUpperCase() + word.slice(1).toLowerCase())
    .join(" ");

  return name;
}

// Auto-apply to modules without explicit titles
export const getExecModuleMetadata = (
  className?: string | null
): ExecModuleMetadata | undefined => {
  if (!className) {
    return undefined;
  }
  const meta = MODULES_BY_CLASS.get(className);

  // Generate proper case title from className if missing
  if (meta && !meta.title) {
    const simpleClassName = className.split(".").pop() || className;
    return {
      ...meta,
      title: convertToProperCase(simpleClassName),
    };
  }

  return meta;
};

🎯 Feature 3: Redux Canvas State with Undo/Redo

Architecture

State Structure:

{
  present: {
    nodes: Node[],
    edges: Edge[],
    selectedNodeId: string | null,
    viewport: { x, y, zoom }
  },
  past: [...previousStates],    // Undo history (max 50)
  future: [...nextStates],       // Redo history
  canUndo: boolean,
  canRedo: boolean,
  isDirty: boolean,
  lastSavedState: string         // Hash for dirty detection
}

Actions

Core Actions:

• initializeCanvas - Load workflow into canvas
• updateNodes - Update nodes (with history)
• updateEdges - Update edges (with history)
• applyNodeChanges - Apply ReactFlow node changes
• applyEdgeChanges - Apply ReactFlow edge changes
• undo - Restore previous state
• redo - Restore next state
• setSelectedNode - Update selection
• updateViewport - Update zoom/pan
• markCanvasSaved - Mark current state as saved
• resetCanvas - Clear canvas

Undo/Redo Logic

History Pattern:

Past: [state1, state2, state3]
Present: state4
Future: []

After undo():
Past: [state1, state2]
Present: state3
Future: [state4]

After redo():
Past: [state1, state2, state3]
Present: state4
Future: []

Limits:

• Maximum 50 states in history
• Automatic cleanup of oldest states
• Deep cloning to prevent mutations

Code

workflowCanvasSlice.ts (400 lines):

// Undo action
undo(state) {
  if (state.past.length === 0) return;

  // Move current to future
  state.future.unshift(cloneState(state.present));

  // Restore from past
  const previous = state.past.pop()!;
  state.present = previous;

  // Update metadata
  state.canUndo = state.past.length > 0;
  state.canRedo = state.future.length > 0;
  state.isDirty = stateHash(state.present) !== state.lastSavedState;
}

// Redo action
redo(state) {
  if (state.future.length === 0) return;

  // Move current to past
  state.past.push(cloneState(state.present));
  if (state.past.length > 50) state.past.shift();

  // Restore from future
  const next = state.future.shift()!;
  state.present = next;

  // Update metadata
  state.canUndo = state.past.length > 0;
  state.canRedo = state.future.length > 0;
  state.isDirty = stateHash(state.present) !== state.lastSavedState;
}

Keyboard Shortcuts

Usage:

// In WorkflowStudio component
useEffect(() => {
  const handleKeyDown = (e: KeyboardEvent) => {
    if (e.metaKey || e.ctrlKey) {
      if (e.key === "z" && !e.shiftKey) {
        e.preventDefault();
        dispatch(undo());
      } else if (e.key === "z" && e.shiftKey) {
        e.preventDefault();
        dispatch(redo());
      }
    }
  };

  window.addEventListener("keydown", handleKeyDown);
  return () => window.removeEventListener("keydown", handleKeyDown);
}, [dispatch]);

🎯 Feature 4: Auto-Save & State Persistence

Persistence Middleware

How It Works:

1. Listens to all workflowCanvas/* actions
2. Debounces saves (300ms) to avoid excessive writes
3. Serializes canvas state to localStorage
4. Only saves if canvas has content (nodes or edges)
5. Includes timestamp for age validation

Storage Key: valkyrAI_workflowCanvas_autosave

Code:

// Middleware auto-saves on every canvas change
export const workflowCanvasPersistenceMiddleware: Middleware =
  (store) => (next) => (action: AnyAction) => {
    const result = next(action);

    if (action.type?.startsWith("workflowCanvas/")) {
      // Debounce saves
      if (saveTimeout) clearTimeout(saveTimeout);

      saveTimeout = setTimeout(() => {
        const canvasState = store.getState().workflowCanvas;

        if (
          canvasState.present.nodes.length > 0 ||
          canvasState.present.edges.length > 0
        ) {
          const dataToSave = {
            present: canvasState.present,
            timestamp: new Date().toISOString(),
            version: "1.0",
          };

          localStorage.setItem(STORAGE_KEY, JSON.stringify(dataToSave));
        }
      }, 300); // 300ms debounce
    }

    return result;
  };

State Restoration

On Mount:

useEffect(() => {
  // Check if there's persisted state
  const persisted = loadPersistedCanvasState();

  if (persisted && !workflowDraft) {
    // Restore from localStorage
    dispatch(
      initializeCanvas({
        nodes: persisted.nodes,
        edges: persisted.edges,
        clearHistory: true,
      })
    );

    console.log("Restored canvas state from localStorage");
  }
}, []);

Age Validation:

• Persisted state expires after 7 days
• Prevents loading stale data
• Automatically cleared on expiry

Functions:

// Load persisted state (with age check)
loadPersistedCanvasState(): State | null

// Clear persisted state
clearPersistedCanvasState(): void

// Check if state exists
hasPersistedCanvasState(): boolean

🎯 Feature 5: Auto-Save on Node Drop

Implementation

Trigger Point: Immediately after node drop on canvas

Workflow:

User drags module → Drops on canvas → onDrop handler
  ↓
Add node to canvas
  ↓
Dispatch updateNodes(newNodes)
  ↓
Redux middleware detects action
  ↓
Debounced save to localStorage (300ms)
  ↓
Canvas state persisted ✅

Benefits:

• No data loss on accidental navigation
• Browser refresh preserves work
• Tab close/reopen restores state
• Network failures don't lose work

🚀 Next Steps

Immediate (Next 2 Hours)

1. Integrate Canvas Slice in WorkflowStudio:

   import { useAppDispatch, useAppSelector } from "../../redux/hooks";
   import {
     initializeCanvas,
     updateNodes,
     selectCanvasNodes,
     selectCanvasEdges,
   } from "../../redux/features/workflows/workflowCanvasSlice";
   
   const nodes = useAppSelector(selectCanvasNodes);
   const edges = useAppSelector(selectCanvasEdges);
   const dispatch = useAppDispatch();

2. Replace Local State with Redux:

   • Remove useNodesState and useEdgesState
   • Use Redux selectors instead
   • Dispatch updateNodes/updateEdges on changes

3. Add Keyboard Shortcuts:

   useEffect(() => {
     const handleKeyDown = (e: KeyboardEvent) => {
       if (e.metaKey || e.ctrlKey) {
         if (e.key === "z" && !e.shiftKey) {
           dispatch(undo());
         } else if (e.key === "z" && e.shiftKey) {
           dispatch(redo());
         }
       }
     };
   
     window.addEventListener("keydown", handleKeyDown);
     return () => window.removeEventListener("keydown", handleKeyDown);
   }, []);

4. Restore State on Mount:

   useEffect(() => {
     const persisted = loadPersistedCanvasState();
     if (persisted && !workflowDraft) {
       dispatch(
         initializeCanvas({
           nodes: persisted.nodes,
           edges: persisted.edges,
           clearHistory: true,
         })
       );
     }
   }, []);

Short Term (Next Day)

1. Add Undo/Redo UI:

   • Button toolbar with undo/redo icons
   • Keyboard shortcut hints
   • Disabled state when can't undo/redo

2. Visual Feedback:

   • Toast notification on auto-save
   • "Restored from autosave" message
   • Dirty indicator in toolbar

3. Clear Button:

   • "Clear Canvas" action
   • Confirmation dialog
   • Clears localStorage

Long Term (Next Week)

1. State Serialization:

   • Export canvas as JSON
   • Import from JSON file
   • Share workflow templates

2. Versioning:

   • Named checkpoints
   • Restore to checkpoint
   • Compare versions

3. Conflict Resolution:

   • Detect concurrent edits
   • Merge strategies
   • "Save as new" option
