ApolloError has networkError prop, but it is set when server responds with 4** or 5** status code.
And how to check that the problem is caused by bad internet connection?
try {
apolloClient.query(someQuery)
} catch (error) {
if (isInternetConnectionError(error)) { // how to check this?
Alert.alert('Please check your internet connection!')
} else {
logException(error);
}
}
Seems that there is not good way to get that (nice work Apollo), but this is the exact error state that comes when there is no internet:
export const isNetworkError = (error: unknown) => {
return (
error instanceof ApolloError &&
error.message === 'Network request failed' &&
error.graphQLErrors.length === 0 &&
error.clientErrors.length === 0 &&
error.networkError &&
Object.keys(error.networkError).length === 0
);
};
Actual for "@apollo/client": "3.4.7"
Or here is much shorter version that should work:
export const isNetworkError = (error: unknown) => {
return (
error instanceof ApolloError &&
error.message === 'Network request failed'
);
};
