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

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.
