I want to make hook to get data from Snapshot to display proposals. I use graphql-request library to get data. I want to get this data in component for example: const { data } = useSnapshotProposalsQuery(). How can i do this? For now i can only get const data = useSnapshotProposalsQuery() and when i am console.log(data) i get Promise{<opening>}. My code:

import { gql, request } from 'graphql-request';

export const useSnapshotProposals = gql`
  query Proposals {
    proposals(
      first: 20
      skip: 0
      where: { space_in: ["example.eth"] }
      orderBy: "created"
      orderDirection: desc
    ) {
      id
      title
      body
      choices
      start
      end
      snapshot
      state
      author
      space {
        id
        name
      }
    }
  }
`;

export const useSnapshotProposalsQuery = () => {
  return request('https://hub.snapshot.org/graphql', useSnapshotProposals).then((data) => data);
};

You create a custom hook. and that hook returns a state. when sideeffect inside that hook happens, the state is updated and your outer component gets re-rendered. (react docs)

export const useSnapshotProposalsQuery = () => {

  const [myData, setMyData] = useState(null);

  useEffect(()=>{
   request('https://hub.snapshot.org/graphql', useSnapshotProposals).then((data) => {setMyData(data)});
  }, []); // run only one time

  return myData;
};

in outer component:

function ABCcomponent () {

 const myData = useSnapshotProposalsQuery(); // it will be null at first, but will be filled with data later.
 
 return (
  /*ui that uses myData */
 )
}
