## `commitMutation`

Imperatively execute a mutation.

See also the [`useMutation`](../use-mutation/) API and [Guide to Updating Data](../../guided-tour/updating-data/introduction.mdx).

```js
import type {FeedbackLikeMutation} from 'FeedbackLikeMutation.graphql';
const React = require('React');

const {graphql, commitMutation} = require('react-relay');

function likeFeedback(environment: IEnvironment): Disposable {
  return commitMutation<FeedbackLikeMutation>(environment, {
    mutation: graphql`
      mutation FeedbackLikeMutation($input: FeedbackLikeData!) {
        feedback_like(data: $input) {
          feedback {
            id
            viewer_does_like
            like_count
          }
        }
      }
    `,
    variables: {
      input: {
        id: '123',
      },
    },
  });
}
```

### Arguments

* `environment`: `IEnvironment`. A Relay environment.
* `config`: [`MutationConfig<TMutation>`](#type-mutationconfigtmutationconfig-mutationparameters).

<MutationConfig />


### Return Value

* A [`Disposable`](#interface-disposable) which:
  * If called before the request completes, will cancel and revert any optimistic updates and prevent the `onComplete` and `onError` callbacks from being executed. It will not necessarily cancel any network request. Will cause the `onUnsubscribe` callback to be called.
  * If called after the initial request completes, will do nothing.

<Disposable />
