Resolvers Everywhere: Rethinking Client and Server Boundaries in GraphQL

Session description

In GraphQL, a resolver is defined as “the internal function for determining the resolved value of a field.” Traditionally, resolvers live exclusively on the server—but should they? Many teams find themselves either duplicating business logic on the client or pushing client-specific concerns into backend code when trying to treat server models as view models. This talk explores an alternative: client-side resolvers. With Relay Resolvers, clients can define fields that combine and transform data locally. We'll walk through how they work and guidance for deciding when logic belongs on the server versus the client.
