Modeling Nested Objects & Relationships
Design schemas that represent hierarchical data and define relationships between different types.
Why Nested Data Matters
Real-world data is rarely flat. It has connections and hierarchies, like an author having multiple books, or a product having many reviews. GraphQL excels at modeling these complex relationships naturally.
This lesson explores how to design your schema to represent data with nested objects and various relationships, making your API more intuitive and powerful.
Understanding Nested Types
A nested object means one type contains another type as a field. For example, an Author might have a list of Book objects they've written.
This allows clients to fetch related data (like all books by an author) in a single GraphQL request, reducing over-fetching and under-fetching.
