@mibto if you’re asking how to make GET requests with Apollo Client, when you setup your ApolloClient instance, pass in an a new HttpLink instance with the property useGETForQueries set to true. Something like:
import { ApolloClient, InMemoryCache, HttpLink } from "@apollo/client";
const link = new HttpLink({
uri: '/graphql',
useGETForQueries: true,
});
const client = new ApolloClient({
cache: new InMemoryCache(),
link
});
