+Add `useNodesData` composable
+
+## 🧙 Example
+
+### Single node id
+
+```ts
+const nodeId = '1'
+
+const data = useNodesData(nodeId)
+
+console.log(data.value) // '[{ /* ... */ }]
+```
+
+### Array of node ids
+```ts
+const nodeIds = ['1', '2', '3']
+
+const data = useNodesData(nodeIds)
+
+console.log(data.value) // '[{ /* ... */ }]
+```
+
+### Asserting data type
+```ts
+import type { Node } from '@vue-flow/core'
+
+interface Data {
+	foo: string;
+	bar: string;
+}
+
+type MyNode = Node<CustomNodeData>
+
+const nodeId = '1'
+
+const data = useNodesData([nodeId], (node): node is MyNode => {
+  return 'foo' in node.data && 'bar' in node.data
+})
+
+console.log(data.value) // '[{ /* foo: string; bar: string */ }]
+```
