How to disable cache in apollo-link or apollo-client?

Question

I'm using apollo-client, apollo-link and react-apollo, I want to fully disable cache, but don't know how to do it.

I read the source of apollo-cache-inmemory, it has a config argument in its constructor, but I can't build a dummy storeFactory to make it works.

Answer 1

You can set defaultOptions to your client like this:

const defaultOptions: DefaultOptions = {
      watchQuery: {
        fetchPolicy: 'no-cache',
        errorPolicy: 'ignore',
      },
      query: {
        fetchPolicy: 'no-cache',
        errorPolicy: 'all',
      },
    }

const client = new ApolloClient({
    link: concat(authMiddleware, httpLink),
    cache: new InMemoryCache(),
    defaultOptions: defaultOptions,

});

fetchPolicy as no-cache avoids using the cache.

See https://www.apollographql.com/docs/react/api/core/ApolloClient/#defaultoptions

Answer 2

Actually, setting fetchPolicy to network-only still saves the response to the cache for later use, bypassing the reading and forcing a network request.

If you really want to disable the cache, read and write, use no-cache. Which is "similar to network-only, except the query's result is not stored in the cache."

Take a look at the official docs: https://www.apollographql.com/docs/react/data/queries/#configuring-fetch-logic

Answer 3

I would always suggest not to disable inbuild caching feature from apollo client. Instead you can always set fetchPolicy: 'network-only' for an individual queries. Something like this

<Query
    query={GET_DOG_PHOTO}
    variables={{ breed }}
    fetchPolicy='network-only'
>
 {({ loading, error, data, refetch, networkStatus }) => {
   ...
 }}
</Query>

While fetching data with this Query, it would always do a network request instead of reading from cache first.
