+## Cache options (alpha.8)

+```ts
+// staleTime — auto-stale after a timeout (ms)
+const cachedTeam = $.resource("cachedTeam", {
+  load: async () => loadTeam(),
+  cache: { staleTime: 50 },
+})
+
+// deduplicate — share in-flight promise between concurrent calls

+  autoLoad: false,
+  cache: { deduplicate: true },
+})
+```
+
+When no `cache` object is set, existing behavior is preserved (no deduplication, no time-based staleness).
