+# Reconnect
+
+If your connection is lost while you are connected to a room, the app will automatically handle the reconnection process. You can monitor these events by utilizing the `useReconnection` hook.
+
+### Example code that logs the current status to the console:
+
+```ts
+import { useEffect, useRef } from "react";
+import {
+  ReconnectionStatus,
+  useReconnection,
+} from "@fishjam-cloud/react-native-client";
+
+function Component() {
+  const prevStatus = useRef<ReconnectionStatus>("idle");
+  const { reconnectionStatus } = useReconnection();
+
+  useEffect(() => {
+    if (prevStatus.current == reconnectionStatus) return;
+    prevStatus.current = reconnectionStatus;
+    if (reconnectionStatus == "error") {
+      console.log("Failed to reconnect");
+    } else if (reconnectionStatus == "reconnecting") {
+      console.log("Connection is broken, reconnecting...");
+    } else {
+      console.log("Connected succesfully");
+    }
+  }, [reconnectionStatus]);
+
+  return <View/>;
+}
+```
