How to modularize GraphQL schema when using `buildSchema`?

Question

It has been about a year since I updated my graphql-js dependency. I see now that there is a utility that simplifies schema generation: buildSchema. This function takes, as an arg, your entire schema, as a string, in the GraphQL language. That's awesome, but is there a way to modularize this? My schema is not super small, and would suck to cram into a single .graphql file. Is there some sort of utility or pattern for storing each type definition in its own file, for example?

Answer 1

If you have the graphql-tools package, you can use makeExecutableSchema to modularize your schema like so:

const schema = makeExecutableSchema({
    typeDefs: [schema1, schema2, schema3, ...],
    resolvers: resolvers,
});

That way each type can be defined in its own file.
