Product Information

Apollo GraphOS provides a managed mode for Apollo Federation, which helps you modify and grow your supergraph without any downtime. However, supporting this composability can be challenging for developers and backend API teams—not to mention that handwriting a backend-for-frontend could be burdensome. It's also responsible for combining multiple subgraph responses into a single response for the client.

It is a gateway such as Tyk, which can look at the different objects in the subgraphs and deliver data flexibly as a result, without the need for you to spend time defining the stitching in the gateway.

Learn GraphQL Today Take your GraphQL skills to the next level with our free interactive GraphQL tutorials, videos, quizzes and code challenges on Odyssey, Apollo's new official learning platform! Apollo GraphOS is the platform for building, managing, and scaling a supergraph : a unified network of your organization's microservices and their data source s—all composed into a single distributed API.

In this structure, the "graph team" might be a separate team that's dedicated to maintaining your router as part of back-end infrastructure, or it might be a "meta team" that includes representatives from other teams that maintain subgraph s. However, this type of platform approach requires careful coordination between frontend and backend teams. Instead, we have to think about how much of the graph an operation may traverse in the context of a single request. If you create a cloud supergraph with GraphOS , Apollo provisions and hosts your supergraph 's router for you! If other browser-based applications will query your supergraph , you need to modify your CORS settings.object includes an sdl field , which includes the full SDL representation of the subgraph 's schema .

After installing, run rover in your terminal with no argument s to confirm that it installed successfully. At the highest level, you can set a timeout on the router 's HTTP server (or an idle timeout on a load balancer in front of it). If you have existing client applications that connect directly to your GraphQL API, you can update their GraphQL endpoint URL to your router's URL. Clients can't include any new schema field s in their queries until your router does know about the changes! It does this through the use of schemas, which specify the types of objects that clients can request when they query the service.Make sure any existing clients that communicate directly with your API are updated to communicate with your router before you begin rejecting direct requests! Most commonly, a particular feature (or concern ) usually spans multiple types, which might belong to different subgraph s. This action is equivalent to removing all of the subgraph 's types and field s from your supergraph (unless they're also defined in another subgraph ).
