Architecture of apollo federation

hello, I want to know in a microservice branch, the resolver.js and schema.graph are necessary? but in the tutorial of odyssey-voyage-II-server there is no any resolvers.js and schema.graphql within it . why?

Hey there @chained_women - There are resolvers and a schema in that repo. You can see them here:

You do need these for the GraphQL server to run.

I think the presence of resolver.js and schema.graphql files depends on the specific implementation and framework used. In the Odyssey Voyage II server tutorial, these files may be omitted because the tutorial might be using an alternative method for defining and resolving GraphQL schemas, such as schema-first development with embedded schema definitions in code.
