 GraphQL by PoP follows the [code-first approach](https://graphql-by-pop.com/docs/architecture/code-first.html) to generate the schema (it can be customized for different clients/applications). Fields are dynamically "subscribed" to types, and may or may not be added to the schema depending on the context.
