Apollo server: cache data between resolvers

Help
1

I have this resolvers:

const resolvers = {
  Query: {
    getCurrencies: async (parent, args, context, info) => {

      //complex operation
      //const currencies = ...
      return currencies;

    },
    getUser: async (parent, args, context, info) => {

      const currencies = await resolvers.Query.getCurrencies(parent, args, context, info);

      // some code to get User
      //const user = ...
      
      return {
        ...user,
        currency: currencies.find(c => c.id === user.currencyId)
      }
    },
    getCountry: async (parent, args, context, info) => {

      const currencies = await resolvers.Query.getCurrencies(parent, args, context, info);

      // some code to get Country
      // const country = ...
            
      return {
        ...country,
        currency: currencies.find(c => c.id === country.currencyId)
      }
    }
  }
}

After in Apollo client I’m using both:

const user = useQuery(GET_USER)
const country = useQuery(GET_COUNTRY)

It’s possible to cache in some way getCurrencies?

A logical option would be pass currencies via client variables:

const currencies = useQuery(GET_USER)
const user = useQuery(GET_USER, {
 variables: currencies
})
const country = useQuery(GET_COUNTRY,{
 variables: currencies
})

But that would add a lot of complexity to my code…

@jdmoliner have you seen the Apollo Server Server-side caching docs?
