Workflow and tooling for GraphQL

As per the data graph (data structure) way of thinking in GraphQL, data is exposed using an API consisting of graphs of objects. These objects are connected using relations. GraphQL only exposes a single API endpoint. Clients query this endpoint, which uses a single data graph. On top of that, the data graph may resolve data from a single source, or multiple sources, by following the OneGraph principle of GraphQL. These sources could be a database, legacy system, or services that expose data using REST/gRPC/SOAP.

The GraphQL server can be implemented in the following two ways:

Standalone GraphQL service: A standalone GraphQL service contains a single data graph. It could be a monolithic app or based on a microservice architecture that fetches the data from single or multiple sources (having no GraphQL API).
Federated GraphQL services: It’s very easy to query a single data graph for comprehensive data fetching. However, enterprise...
