GraphOS Studio is the final piece of the puzzle for building and operating a supergraph. Its delivery pipeline provides the validation, automation, and observability you need to deliver changes rapidly and safely, making it possible to constantly evolve the supergraph schema, particularly when teams leverage and extend each other’s contributions.

Note that if you use Federation 1 composition and any of your subgraph s uses a Federation 2 schema , composition will fail! In addition to the l Post: This implements the post data and can retrieve the information about the author (that’s a specific type of user) Set the APOLLO_KEY and APOLLO_GRAPH_REF environment variable s in the router 's deployment environment, as we did locally in this step .

Supports GraphQL federation natively

Consider using 3-way merges and overriding the APOLLO_VCS_COMMIT and/or APOLLO_VCS_BRANCH to correlate schema changes for subgraph changes. A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Are you sure you want to create this branch?

If composition succeeds, the variant 's router automatically begins using the updated supergraph schema . This means clients can no longer query the router for field s that are defined only in the deleted subgraph . routing_url is the URL the Apollo Router will use to send GraphQL operations to a subgraph at runtime To add a subgraph to your supergraph with Rover , you publish the subgraph's schema ! To do this, you use the exact same Rover command as updating an existing subgraph . The only difference is that you provide the name of the new subgraph to the command. Initially developed by Facebook, which provided just a reference implementation, GraphQL was mostly implemented in the JS ecosystem in Apollo and Mercurius. Speaking of references, I recommend you view the mercurius-apollo-playground repo created by Andrea Carraro. It provides you with invaluable context because it contains the code and the benchmark commands for the project that inspired this blog post.Each subgraph is itself a GraphQL API. Therefore, it uses a GraphQL server library to handle queries forwarded along by your graph router .

The URLs may or may not be the same; in this case, the URLs differ. For example, planets-service.schema.subgraph_url is http://localhost:8001 because I If you already have an Apollo account, and you created your organization prior to October 2022, you might need to create a new organization to create cloud supergraph s: It can be challenging to represent an entire enterprise-scale graph with a monolithic GraphQL server. Performance might degrade as your users and features increase, and teams across your organization are all committing changes to the same application:

Note: The generated ./graph-api.env holds your APOLLO_KEY and APOLLO_GRAPH_REF. Publish Subgraph Schemas to the Apollo Registry
