+title: Mutation Options
+---
+
+One of the best ways to share mutation options between multiple places,
+is to use the `mutationOptions` helper. At runtime, this helper just returns whatever you pass into it,
+but it has a lot of advantages when using it [with TypeScript](../typescript.md#typing-query-options).
+You can define all possible options for a mutation in one place,
+and you'll also get type inference and type safety for all of them.
+
+```ts
+export class QueriesService {
+  private readonly http = inject(HttpClient)
+
+  updatePost(id: number) {
+    return mutationOptions({
+      mutationFn: (post: Post) => Promise.resolve(post),
+      mutationKey: ['updatePost', id],
+      onSuccess: (newPost) => {
+        //           ^? newPost: Post
+        this.queryClient.setQueryData(['posts', id], newPost)
+      },
+    })
+  }
+}
+```
