Should Apollo retryLink
come before or after the errorLink
? Some examples show it as before https://medium.com/@joanvila/productionizing-apollo-links-4cdc11d278eb#3249 while some show it after https://www.apollographql.com/docs/react/api/link/apollo-link-rest/#link-order.
It depends how you want your errorLink
logic to work, from the docs
Additive composition involves combining a set of links into a serially executed chain
and the Error Link
is called after the GraphQL operation completes and execution is moving back up your link chain
so if you place the retryLink
before the errorLink
ApolloLink.from([retryLink, errorLink])
the errorLink
will also be executed with the retries once the respective result is traveling back up the chain, in other words (if you are using the default docs example), there should be a console log on every attempt and attempts.max
console logs in total.
In case the order is flipped the errorLink
will be called after the retryLink
is complete and the result traveled all the way back up, so there should be 1 console log from the errorLink
call.
