Is it possible to persist in localstorage (or similar) until offline is ready?

I read docs on website and offline RFC issue.

But then I saw this code in this file: https://github.com/FormidableLabs/urql/blob/master/exchanges/graphcache/src/cacheExchange.ts

export interface CacheExchangeOpts {
  updates?: Partial<UpdatesConfig>;
  resolvers?: ResolverConfig;
  optimistic?: OptimisticMutationConfig;
  keys?: KeyingConfig;
  schema?: IntrospectionQuery;
  storage?: StorageAdapter;
}

So the questionis:

Until https://github.com/FormidableLabs/urql/issues/683 is ready, is it possible to use localstorage today at least temporarily?

Something like: https://github.com/apollographql/apollo-cache-persist?

The persistence is indeed already functional and you can find an example of this in our persisted-store sample app: https://github.com/FormidableLabs/urql/blob/master/exchanges/graphcache/examples/persisted-store/src/app/index.tsx

That persistence is fully functional but we may make small tweaks to the API as we’re adding full offline support. Overall it should be stable and work correctly, but do treat it as experimental until it’s documented and announced please ♥️

When you use it, it should fully work as expected minus what’s mentioned in the RFC, eg optimistic mutations having special handling when a mutation fails due to being offline, or ignoring certain errored results.

I ask you to wait a little longer before closing this: I will try this today.

Well, the question itself is answered so the typically close the issue out after a response.

But don’t worry, you can keep commenting and ask more questions if you need, even when the issue is closed! 🙌

Btw, I’ve noticed you’re opening a lot of issues that end up being questions rather than bugs or actual issues. Maybe you’ll want to take a look at our Spectrum community? It may be a better place for us to help you with questions since it’s more of a message board / forum
