-- `__tests__` contains the unit tests.
-- `__tests-pacts__` contains the contract test.
-- `src/internals` contains a couple of internal data structures. In most cases, you won't need to touch this. Here we hide complexity that isn't needed for typical development tasks.
-- `src/model` defines the model.
-- `src/schema` defines the GraphQL schema.
