Why a GraphQL Client?

In the Clients section in the GraphQL part, we already covered the responsibilities of a GraphQL client on a higher level, now it’s time to get more concrete.

In short, you should use a GraphQL client for tasks that are repetitive and agnostic to the app you’re building. For example, being able to send queries and mutations without having to worry about lower-level networking details or maintaining a local cache. This is functionality you’ll want in any frontend application that’s talking to a GraphQL server – why build it yourself when you can use one of the amazing GraphQL clients out there?
