| mutationFn: postTodo, | |
| })) | |
| ``` | |

| ```ts | |
| import { | |
| injectMutation, | |
| QueryClient, | |
| } from '@tanstack/angular-query-experimental' | |
| export class TodosComponent { | |
| queryClient = inject(QueryClient) | |
| // When this mutation succeeds, invalidate any queries with the `todos` or `reminders` query key | |
| mutation = injectMutation(() => ({ | |
| mutationFn: addTodo, | |
| onSuccess: () => { | |
| this.queryClient.invalidateQueries({ queryKey: ['todos'] }) | |
| this.queryClient.invalidateQueries({ queryKey: ['reminders'] }) | |
| }, | |
| })) | |
| } | |
| ``` | |
| [//]: # 'Example2' | |
| You can wire up your invalidations to happen using any of the callbacks available in the [`injectMutation` function](../mutations.md) | |
