Function: createEditorStore()

function createEditorStore(overrides?): UseBoundStore<Write<StoreApi<EditorStore>, {
  temporal: StoreApi;
}>>;

Defined in: packages/visual-editor/src/store/editor-store.ts:416

Create an isolated zustand editor store instance.

Parameters

Parameter	Type	Description
overrides?	Partial<EditorState>	Optional partial initial state to override defaults.

Returns

UseBoundStore<Write<StoreApi<EditorStore>, { temporal: StoreApi; }>>

A zustand useStore hook bound to the new isolated store.

Remarks

Returns a new zustand useStore hook bound to a fresh store instance. Use this when embedding multiple independent RuneTypeGraph components in the same React tree — each graph must own a separate store.

The store is wrapped with zundo temporal middleware for undo/redo support. Access undo/redo via useTemporalStore.

Use When

• Rendering two or more RuneTypeGraph components simultaneously (different namespaces, split-pane editors, etc.)
• Writing tests that need an isolated store per test case

Avoid When

• You only need a single graph — use the pre-created useEditorStore singleton.

Pitfalls

• Each createEditorStore() call allocates a new Zustand store + Zundo temporal tracker. Do NOT call this inside a render function — call once at module level or in a useState initializer.
