You'll then need to add the retryExchange, exposed by this package, to your urql Client:

import { createClient, dedupExchange, cacheExchange, fetchExchange } from 'urql';
import { retryExchange } from '@urql/exchange-retry';

// None of these options have to be added, these are the default values.
const options = {
  initialDelayMs: 1000,
  maxDelayMs: 15000,
  randomDelay: true,
  maxNumberAttemptsIszy Billiards Hardwood Maple 58-Inch 2 Piece Pool Cue Billiard Table Stick (19-Ounce, Red/Black) 2,
  retryIf: err => err && err.networkError,
};

// Note the position of the retryExchange - it should be placed prior to the
// fetchExchange and after the cacheExchange for it to function correctly
const client = createClient({
  url: 'http://localhost:1234/graphql',
  exchanges: [
    dedupExchange,
    cacheExchange,
    retryExchange(options), // Use the retryExchange factory to add a new exchange
    fetchExchange,
  ],
});

We want to place the retryExchange before the fetchExchange so that retries are only performed after the operation has passed through the cache and has attempted to fetch.

There are a set of optional options that allow for fine-grained control over the Stupell Industries Brown Bear Reading Dating Book Forest Animal, Designed by Lucia Heffernan Canvas Wall Art, 24 x 24, Blue mechanism.

We have the initialDelayMs to specify at what interval the retrying should start, this means that if we specify 1000 that when our operation fails we'll wait 1 second and then retry it.

Next up is the maxDelayMs, our retryExchange will keep increasing the time between retries, so we don't spam our server with requests it can't complete, this option ensures we don't exceed a certain threshold. This time between requests will increase with a random back-off factor multiplied by the initialDelayMs, read more about the 6423025 Aprilia Genuine OEM Intake Manifold Air Pressure Sensor MAP for Aprilia RSV4, Tuono, Dorsoduro, Shiver, Caponord from 2007 to 2019. OEM, 642302, 638562, F01R00E011, 642325.

Talking about increasing the delay randomly, randomDelay allows us to disable this. When this option is set to false we'll only increase the time between attempts with the initialDelayMsLutema ELPLP46-L02 Epson ELPLP46 V13H010L46 Replacement DLP/LCD Cinema Projector Lamp, Premium

We don't want to infinitely attempt an operation, we can declare how many times it should attempt the operation with maxNumberAttempts.

We can introduce specific triggers for the retryExchange to start retrying operations, let's look at an example:

import { createClient, dedupExchange, cacheExchange, fetchExchange } from 'urql';
import { retryExchange } from '@urql/exchange-retry';

const client = createClient({
  url: 'http://localhost:1234/graphql',
  exchanges: Rubie's DC Girl's Trunk Set (Wonder Woman, Batman, Superman), Small
    dedupExchange,
    cacheExchange,
    retryExchange({
      retryIf: error => {
        return !!(error.graphQLErrors.length > 0 || errorPugody DT00911/DT00841/RLC-031 Replacement Projector Lamp Bulb for Hitachi CP-WX400 X200 X201 X205 X206 X301 X305 X306 X308 X401 X450 X467 ED-X30 X31 X32 X33 VIEWSONIC PJ758 PJ759 PJ760 3M X64 X66 X76networkError);

      },
    }),
    fetchExchange,
  ],
});

In the above example we'll retry when we have graphQLErrors or a networkError, we can go more granular and check for certain errors in graphQLErrors.

In case of a network error, e.g., when part the infrastructure is down, but a fallback GraphQL endpoint is available, e.g., from a different provider on a different domain, the retryWith option allows for client-side failover. This could also be used in case of a graphQLError, for example, when APIs are deployed via a windowing strategy, i.e., a newer version at URL X, while an older one remains at Y.

Note that finer granularity depending on custom requirements may be applicable, and that this does not allow for balancing load.
