Using skipToken
in that manner will immediately put the query into fetchPolicy: "standby"
, which should never issue a network request.
This is highly curious. Could you provide us with a reproduction showing that happening?
I have figured out that the problem has to do with <React.StrictMode>
somehow (StrictMode
causes render functions to be called twice, among other things). Without StrictMode
, the skipping works as intended. Under StrictMode
, both skipToken
and {skip: true}
seem to not result in skipping.
The repro seems to be as simple as:
const client = new ApolloClient({
uri: "/graphql",
connectToDevTools: true,
cache: new InMemoryCache(),
});
ReactDOM.createRoot(document.getElementById("root")!).render(
<React.StrictMode>
<ApolloProvider client={client}>
<DummyComponent />
</ApolloProvider>
</React.StrictMode>,
);
export const DummyComponent: React.FunctionComponent<
PropsWithChildren<unknown>
> = ({children}) => {
console.log("!!! DummyComponent render");
let data: GetSpecQuery;
const {data: res} = useQuery(GET_BINARIES, skipToken);
console.log("!!! DummyComponent. data: ", res);
return <>DummyComponent</>;
};
FWIW, useQuery
with {skip: true}
works fine (including under StrictMode
).
Please tell me if this doesn't repro and I'll work on packaging it somehow.
@andreimatei out of curiosity, is this reproducible using version 3.9.9? Also in the code snippet above, I'm assuming you meant {skip: true}
instead of skipToken
as being passed to useQuery
? As useQuery
does not accept skipToken
.

No, it does not seem to reproduce on 3.9.9! So the issue seems to have been introduced in 3.9.10. Going back and forth between these two versions reliably introduces and removes the problem.
Also in the code snippet above, I'm assuming you meant {skip: true} instead of skipToken as being passed to useQuery? As useQuery does not accept skipToken.
Sorry, the snippet was supposed to use useSuspenseQuery
. It was supposed to be
export const DummyComponent: React.FunctionComponent<
PropsWithChildren<unknown>
> = ({children}) => {
console.log("!!! DummyComponent render");
let data: GetSpecQuery;
const {data: res} = useSuspenseQuery(GET_BINARIES, skipToken);
console.log("!!! DummyComponent. data: ", res);
return <>DummyComponent</>;
};
useQuery
works fine.
Thanks for confirming that, @andreimatei! I believe @jerelmiller has some thoughts here on how to reconcile the fix we shipped in 3.9.10 with the issue you're seeing. We're also working on releasing 3.10 this week, so I can't give a precise timeline on the fix here, but we're looking into it. Thanks!
167 useSuspenseQuery
tests and this wasn't one of them 😂. Thanks for reporting!

Issue Description
I'm unconditionally using
skipToken
and yet thisuseSuspenseQuery
call produces a network request for the respective query.Am I misunderstanding that
skipToken
is supposed to not generate a request? Or what could be the matter?Link to Reproduction
