Function: reconcileArrayById()#

function reconcileArrayById<TItem, TKey>(idKey): IStateReconciler<TItem[]>;

Defined in: retree-query/src/reconcile.ts:31

Create a reconciler for arrays of objects with stable IDs.

Type Parameters#

Parameters#

Returns#

IStateReconciler<TItem[]>

A reconciler that updates matching array items in place.

Remarks#

Use this for arrays whose items have stable IDs. Reconciliation updates matching items in place so child object identity stays stable for useNode(item) rows and Retree parent relationships.

Do not use index-based reconciliation for lists that can reorder. Prefer a stable ID from the server.

Example#

const node = new QueryNode(source, {
    args: { projectId },
    reconcile: reconcileArrayById("id"),
});
