refactor: enhance z-index management for nodes and remove unused hook #1896
Conversation
- Implemented z-index management for nodes in the Flow component based on the selected node. - Removed the useSelectedNodeZIndex hook from various node components to streamline logic and improve performance. - Updated the prepareAddNode utility to conditionally connect nodes based on their type. - Ensured compliance with coding standards, including optional chaining and nullish coalescing for safer property access.
WalkthroughCentralizes z-index management from individual node hooks to a shared Flow component effect; removes the distributed Changes

400-407: Consider separating z-index reset into a dedicated effect.The z-index reset logic is currently embedded in the event handler registration effect (lines 381-420), mixing two distinct concerns. This could lead to unnecessary z-index resets whenever any of the event handler dependencies change.
🔎 Proposed refactor to separate concerns
Move the z-index reset into its own effect that runs only once on mount:
+ // Reset z-index for memo nodes on mount + useEffect(() => { + setNodes((nodes) => + nodes.map((n) => { + if (n.id === id) { + return { ...n, style: { ...n.style, zIndex: 0 } }; + } + return n; + }), + ); + }, [id, setNodes]); + // Add event handling useEffect(() => { // Create node-specific event handlers const handleNodeAddToContext = () => handleAddToContext(); const handleNodeDelete = () => handleDelete(); const handleNodeInsertToDoc = () => handleInsertToDoc(); const handleNodeAskAI = (event?: { dragCreateInfo?: NodeDragCreateInfo; }) => handleAskAI(event); const handleNodeDuplicate = (event?: { dragCreateInfo?: NodeDragCreateInfo; }) => handleDuplicate(event); // Register events with node ID nodeActionEmitter.on(createNodeEventName(id, 'addToContext'), handleNodeAddToContext); nodeActionEmitter.on(createNodeEventName(id, 'delete'), handleNodeDelete); nodeActionEmitter.on(createNodeEventName(id, 'insertToDoc'), handleNodeInsertToDoc); nodeActionEmitter.on(createNodeEventName(id, 'askAI'), handleNodeAskAI); nodeActionEmitter.on(createNodeEventName(id, 'duplicate'), handleNodeDuplicate); - setNodes((nodes) => - nodes.map((n) => { - if (n.id === id) { - return { ...n, style: { ...n.style, zIndex: 0 } }; - } - return n; - }), - ); - return () => { // Cleanup events when component unmounts nodeActionEmitter.off(createNodeEventName(id, 'addToContext'), handleNodeAddToContext); nodeActionEmitter.off(createNodeEventName(id, 'delete'), handleNodeDelete); nodeActionEmitter.off(createNodeEventName(id, 'insertToDoc'), handleNodeInsertToDoc); nodeActionEmitter.off(createNodeEventName(id, 'askAI'), handleNodeAskAI); nodeActionEmitter.off(createNodeEventName(id, 'duplicate'), handleNodeDuplicate); // Clean up all node events cleanupNodeEvents(id); }; }, [id, handleAddToContext, handleDelete, handleInsertToDoc, handleAskAI, handleDuplicate]);This improves maintainability by:
- Separating z-index initialization from event handling
- Ensuring z-index is only reset once on mount (or when id/setNodes change)
- Making the event registration effect focus solely on event handler lifecycle
Based on learnings, extract complex logic into custom hooks or separate effects for better code organization.

🔇 Additional comments (5)
packages/canvas-common/src/utils.ts (1)
73-73: LGTM! Memo node exclusion from auto-connect is consistent with the broader architecture.The conditional logic correctly prevents memo nodes from automatically connecting to the start node, aligning with the special handling of memo nodes throughout this PR (orphan-node disconnection, z-index management).
packages/ai-workspace-common/src/hooks/use-handle-orphan-node.ts (1)
78-81: LGTM! Memo node handling is clear and aligns with the PR's architectural changes.The early-exit pattern cleanly ensures memo nodes are disconnected from the start node and skip further orphan processing, consistent with the memo-specific behavior introduced across this PR.

onHoverStartcall now includes theselectedstate, and the dependency array properly includesselectedto avoid stale closures.

1079-1095: LGTM! Centralized z-index management successfully replaces per-node hooks.The effect correctly applies z-index styling to bring the selected node to the foreground (z-index 1000) while keeping others at z-index 1. Memo nodes are appropriately skipped, maintaining their independent z-index handling.
The dependency array includes
reactFlowInstance, which is a stable reference fromuseReactFlow, so it won't cause unnecessary re-renders.
