So when should you use either one? Many will say that federation is the overall winner, as it allows teams to focus on their application without needing to maintain a gateway. But if you have different types of APIs, you have to go with schema stitching. The supergraph eliminates that complexity by enabling and automating organization-wide composability that delivers better performance and This feature is only available with a GraphOS Enterprise plan.If your organization doesn't currently have an Enterprise plan, you can test this functionality by signing up for a free Enterprise trial. We can use the @apollo/gateway or @mercuriusjs/gateway modules to create the gateway. The integration of both technologies is similar: You should manage internal access to your supergraph as thoughtfully as you manage communication from external clients. GraphOS provides both graph API keys and personal API keys to restrict access to the graphs within an organization. It also supports SSO integration and different member roles so that team members can be assigned appropriate permissions when contributing the graph.

This initial schema fetch is a one-time action to help you get started. Whenever your API's schema changes , Studio doesn't automatically fetch it again. This means your router doesn't know about those changes. Clients can't include any new schema field s in their queries until your router does know about the changes! The services created above expose the GraphQL endpoint and run on ports 4001 and 4002. The introspection action of the gateway calls the endpoint, merges the subgraph schemas, and provides the client with a unified schema. Implement the supergraph gateway with Apollo gateway Complete the first step of Get started with GraphOS ( Create your Apollo account ), then return here. Create a graph in GraphOS StudioThe exact details for deploying the router depend on which platform you use, but these high-level steps hold true for most platforms: An an intermediate level, you can set a timeout on the router 's requests to individual subgraph s. You can configure timeouts at both the HTTP and subgraph levels using the Apollo Router's traffic shaping configuration .

Many GraphQL servers improve their developer experience by providing detailed error information in operation responses when something goes wrong. In your production supergraph , make sure that verbose error details are removed from API responses. Rather than relying on custom code to combine subgraphs, subgraphs reference and extend each other through a principled set of primitives. Thanks to our incredible developer community, Federation supports subgraphs written in over 20 programming languages and a growing number of GraphQL-native services and products.In addition to the library I showed you previously in this blog post, Apollo provides a high-performance router that is built in Rust.
