[Documentation] useMutation example for Vue Composition API about graphql-code-generator-community

[spencerbull]

@DarkLite1 I was having the same issue, so thanks for posting the question and ask for documentation.

To extend on what @cdrx mentioned, you cannot "initialize" the mutate by const { mutate, loading, error, onDone } = useSetLanguageMutation()

You need to initialize it with an empty object. const { mutate, loading, error, onDone } = useSetLanguageMutation({})

Then you can call mutate({ language: newLanguage })

[cdrx]

Anything you pass to mutate() is merged with anything you pass to useSetLanguageMutation({variables: ... }) so it can work both ways.

In your case uou can pass your variables directly to mutate(), you don't need to pass them to useSetLanguageMutation({variables: ...}) also.

The functions created by this library are thin wrappers around vue-apollo's composition API, you can find some documentation here: https://v4.apollo.vuejs.org/guide-composable/mutation.html
