Exploring Type Definitions in Vue Apollo version 4 and the Composition API

How can TypeScript be informed that Variables is the interface for the arguments of the myMutation function?

    interface Variables {
      uuid: string;
      value: string;
    }

    const { mutate: myMutation } = useMutation(myGqlMutation);

I am looking for an alternative to using myMutation like this:

 myMutation({
     uuid: '....',
     value: '....',
 } as any); // eliminate the use of any here ... 

Answer №1

Add generics to the useMutation function, as demonstrated here:

interface DataInput {
  id: number;
  name: string;
}

const { mutate: myFunction } = useMutation<{ input: DataInput }>(myGqlMutation);

For more information, refer to the documentation
