Overview

System uses GraphQL as its primary API layer for all core applications including Headless CMS, Website Builder, and File Manager. GraphQL provides a flexible, type-safe way to query and mutate data, allowing clients to request exactly the data they need.

GraphQL Schema Factory
anchor

System implements a factory pattern for building GraphQL schemas. The GraphQLSchemaFactory interface allows you to extend and customize the GraphQL API by:

  • Adding type definitions - Define your own GraphQL types, inputs, queries, and mutations
  • Registering resolvers - Implement the logic that handles GraphQL operations
  • Dependency injection - Access services and use cases within your resolvers
  • Modular architecture - Build your schema in a composable, maintainable way

This approach keeps your GraphQL layer thin and focused on data access, while business logic lives in dedicated service classes. You can extend existing schemas or create entirely new GraphQL APIs that integrate seamlessly with the system’s infrastructure.
