Building Custom Directives
Create your own schema directives to add custom logic, validation, or transformation to your GraphQL fields.
Directives: Extending GraphQL
GraphQL directives are powerful tools that allow you to add custom behavior or metadata to your schema. You might already know built-in directives like @deprecated or @skip.
Custom directives let you define your own, extending GraphQL's capabilities to fit your unique application needs.
Power of Custom Directives
Custom directives offer several benefits:
- Reusability: Apply the same logic across multiple fields or types without repeating code.
- Separation of Concerns: Keep business logic separate from schema definitions.
- Cross-Cutting Concerns: Easily add features like logging, authorization, or validation to many parts of your API.
