We think it’s time to give this architecture a name, and after talking about it with the developers that have pioneered this approach in their companies, we’re calling it the supergraph. The principles of supergraph architecture Next, we'll cover some of the most common and important actions to perform on your new supergraph , including: Cloud supergraph s require an Apollo organization on the Serverless (Free) or Serverless plan. Learn more about plans. A microservices-like approach enables you to split the responsibilities into different services that can be maintained by separate teams and deployed in different ways.

header propagation: Apollo Router will remove all headers from an original GraphQL request and insertA self-hosted supergraph is a supergraph with a router that you host and manage in your own infrastructure . This is in contrast to a cloud supergraph , which uses a router that's hosted and managed by Apollo.

Learn morerole header from context to requests to all subgraphs (inserting a user’s role to context is performed by a custom Apollo Router plugin; it will be shown later) Platforms such as Shopify and GitHub are other good examples of what GraphQL is used for, as public APIs like this, with large groups of unknown users, need GraphQL’s flexibility in terms of satisfying so many different use cases. How Netflix scales its API with GraphQL federation is another strong example of GraphQL in action. The supergraph eliminates that complexity by enabling and automating organization-wide composability that delivers better performance and

Here's a powerful benefit of a cloud supergraph : because clients execute operation s against your GraphOS -managed router , the router automatically collects metrics on those operations and their field s. You can then visualize those metrics in Studio. You can omit @ and the variant name. If you do, Rover uses the default variant, named current . Composing a supergraph schema supergraph compose These are all customizable, open-source libraries with powerful caching and state management features. Client-side caching enables an application to locally replicate the parts of your supergraph that it cares about. The application can then query itself for data if it's already present, which dramatically improves performance by eliminating redundant network requests. Where do I start? Important: CI systems wipe away any persisted Rover configuration on each run, and they can't accept the interactive ELv2 prompt. To automatically accept the prompt in CI, do any of the following: Validating and sanitizing client-submitted data is important for any API, and a supergraph is no exception. In general, the usual rules for validation and sanitization of untrusted inputs apply to GraphQL when resolving field s based on user-provided inputs. And as previously discussed, when users supply invalid values as operation argument s, the resulting errors should provide as few details as possible in production environments.A real supergraph schema includes additional information that tells your router which subgraph is responsible for which types and field s. Learn more about composition. Server instances The Query._service object includes an sdl field , which includes the full SDL representation of the subgraph 's schema . This field exposes as much data about a subgraph's schema as a standard introspection query, which means it should not be accessible in production . Now all that’s left is for you to create your own hybrid system with Mercurius and Apollo, when the time is right for you to do so. Resources Let's execute some test queries against the supergraph . We'll look at metrics for those test queries in the next step. 7. View operation and field metrics Tyk and Apollo work well in parallel. Following is a general guide on how to implement federation with Apollo. Creating a gateway
