Is there  an example somewhere of using Apollo Client's optimistic UI when doing a nested mutation?

<@U42DA0Q66> not that I'm aware of, did you set up Apollo's optimistic UI for normal mutations already?

How does that differ from nested mutations?

here is the documentation I'm looking at: <http://dev.apollodata.com/react/optimistic-ui.html>

In their example, `submitComment` creates a comment

but if I use `updateUser` to create a team and associate that team with a user, then two things are changing, and a relationship between those two things is also created

```
          optimisticResponse: {
            __typename: 'Mutation',
            submitComment: {
              __typename: 'Comment',
              postedBy: ownProps.currentUser,
              createdAt: +new Date,
              content: commentContent,
            },
          },
```

you can replace `submitComment` with `updateUser`, and then have a key `team` and the value is a team object

so instead of `submitComment` would I just have an `updateUser`, or would I also have a `createTeam` in there?

```
optimisticResponse: {
  __typename: 'Mutation',
  updateUser: {
    __typename: 'User',
    team: {
      __typename: 'Team'
      name: 'Some team'
    },
  },
},
```

`updateQueries` works differently, you need to include a key for every query that you want to update

```
updateQueries: {
  // Would update the query that looks like:
  // query myUserQuery { ... }
  myUserQuery: (previousResult, { mutationResult }) =&gt; {
    // ...
  },
  myTeamQuery: (previousResult, { mutationResult }) =&gt; {
    // ...
  },
}
```
