How does pagination work with custom DTOs?

The skill shows how to use the API Platform Pagination service and the TraversablePaginator to return paginated lists of DTOs correctly.

Why use DTOs instead of entities in API Platform?

DTOs decouple your public API contract from your internal database schema, improving security and allowing both to evolve independently without breaking changes.

Can I have different shapes for requests and responses?

Absolutely. This skill demonstrates how to configure separate Input and Output DTOs to ensure users only send or receive the data necessary for a specific operation.

Does this work with any data source?

Yes. Because DTO resources use custom State Providers, you can fetch data from SQL, NoSQL, external APIs, or even local files.

Desarrollo de API

Implements API-first design in Symfony by decoupling API resources from database entities using pure Data Transfer Objects (DTOs).

Acerca de

This skill provides a comprehensive guide and implementation pattern for using plain PHP classes (DTOs) as API Platform resources instead of traditional Doctrine entities. By moving logic into custom State Providers and Processors, it allows developers to create clean, versionable, and secure API contracts that are completely decoupled from the underlying database schema. This approach is ideal for complex business logic, multi-source data aggregation, and maintaining strict separation of concerns in modern Symfony applications.
