+<summary>Preventing hydration errors when server default value should be different from client default value</summary>
+<p></p>
+
+Using the `defaultValue` property to differ between server and client default values will cause hydration errors. To prevent them you can use the `defaultServerValue` property.
+
+```tsx
+// this will throw hydration error
+const [state, setState] = useLocalStorageState(
+    'key',
+    {
+      defaultValue() {
+        if (isServer) {
+          return "server default value";
+        }
+        return "client default value";
+      },
+    },
+  );
+```
+
+`defaultServerValue` will overwrite `defaultValue` in the `useSyncExternalStore()` hook's `getSnapshot()` function.
+Difference is server's `getSnapshot()` will run on server and client's hydration, then `defaultValue` or local storage value will be used after that.
+
+```tsx
+const [state, setState] = useLocalStorageState(
+    'key',
+    {
+      defaultValue: "client default value",
+      defaultServerValue: "server default value",
+    },
+  );
+```
+
+> Example use cases: You want to show a modal when the user's first enter and you are persistently storing that data on `localStorage`. Using `defaultServerValue` will allow you to show the modal only on the server.
