Collection of libraries and how they import from `graphql`

[phryneas]

In the April meeting of the graphql-js-wg, there was discussion about bundling changes in the graphql package (#4062).
As these changes would also add an exports field, @benjie suggested that we might want to have a restrictive set of exports entry points (only graphql, maybe one or two more?), to discourage from deep-importing from implementation details we do not consider the public interface of the library and which would result in uninteded breaking changes upon e.g. code reorganization.

In this issue, we want to collect libraries and how they are importing from graphql, to ensure that this is a feasible idea so we can discuss this further in the next graphql-js-wg meeting.

If you are generally opposed to a change like this, this issue (or the next WG meeting) are a good place to write your concerns down :)

@apollo/client

Where do you import from in your library?

• graphql

(If you use deep imports) why do you use deep imports?

• yes
• no

graphql-tag

Where do you import from in your library?

• graphql
• graphql/language/ast

(If you use deep imports) why do you use deep imports?

Maybe for historical reasons, but everything we import is also exported from graphql itself.

Would it be okay for you only import from graphql, too?

• yes
• no

grafast

Where do you import from in your library?

• graphql
• graphql/jsutils/PromiseOrValue
• graphql/execution/execute
• graphql/type/schema

(If you use deep imports) why do you use deep imports?

• graphql/jsutils/PromiseOrValue
  • the type isn't exported directly, and redefining it in every file is annoying. Also, auto-import pulls it in
• graphql/execution/execute (specifically the buildExecutionContext function)
  • In order to emulate GraphQLResolveInfo as used in GraphQL resolvers, Grafast needs to get the same execution context. It also needs to coerce the variables and do all the other things that buildExecutionContext does (and isn't where Grafast adds value); so it makes sense to use the underlying function.
• graphql/type/schema
  • specifically the type GraphQLSchemaNormalizedConfig which is marked as internal but used as the return type of schema.toConfig(). Could be worked around via ReturnType<GraphQLSchema['toConfig']> or similar.

Would it be okay for you only import from graphql, too?

• yes
• no

graphql-hive

Where do you import from in your library?

• graphql

(If you use deep imports) why do you use deep imports?

• import { validateSDL } from 'graphql/validation/validate' - as I only need to validate SDL, not build GraphQLSchema

Would it be okay for you only import from graphql, too?

• yes
• no

graphql-yoga

Where do you import from in your library?

• graphql
• graphql/jsutils/Maybe (only in tests for convenience)
• graphql/validation/validate (only for test helpers)
• graphql/validation/ValidationContext (for tests)

(If you use deep imports) why do you use deep imports?

See comments behind the import - we only use them in tests for testing specific features of the GraphQL server

Would it be okay for you only import from graphql, too?

• yes (if the things are exported from the main graphql entry, as it would be annoying to double maintain the declarations ourself
• no
