What is Apollo?
When exploring the C#Bot Technology List: Server-Side used by C#Bot, we discussed how we use GraphQL to query the database. On the client-side, Apollo facilitates communication with GraphQL API, which is presented by the server-side. In essence, Apollo is an implementation of the GraphQL specification, and a way of binding data to the User Interface using GraphQL.
An example usage of Apollo is shown below:
function useLoading<T>(request: DocumentNode) {
const [loading, setLoading] = useState(true);
const [error, setError] = useState("");
const [data, setData] = useState<T>();
useEffect(() => {
store.apolloClient
.query<T>({ query: request })
.then((d) => {
console.log(d);
setLoading(false);
setData(d.data);
})
.catch((e) => {
console.log(e);
setLoading(false);
setError(e);
});
}, [request]);
return { loading, error, data };
}
