What is a DTO in the context of API Platform?

A Data Transfer Object (DTO) is an object used to represent the data sent to or received from an API, allowing you to separate the public API contract from your internal database entities.

How does the skill handle the mapping between DTOs and Entities?

It generates specialized State Providers (for reading) and State Processors (for writing) that manage the transformation logic between your DTOs and your Symfony entities.

Does it automatically update my existing Entity classes?

It updates the #[ApiResource] attribute on your entity to register the new DTO classes, providers, and processors, but it does not modify your core entity properties.

Does this skill handle validation for Input DTOs?

Yes, it generates Input DTOs with Symfony Validator constraints, ensuring data is validated before it is ever transformed into an entity.

Can I generate only an Output DTO without an Input DTO?

Yes, the skill provides an interactive workflow where you can choose to generate an Input DTO, an Output DTO, or both simultaneously.

API Development

Automates the creation of Input/Output Data Transfer Objects (DTOs), State Providers, and Processors for API Platform resources.

This skill streamlines the implementation of the DTO pattern in API Platform applications by generating boilerplate code for data transfer, mapping, and state management. It handles the creation of immutable Output DTOs for data exposure and validated Input DTOs for data ingestion. By automatically scaffolding the necessary Symfony State Providers and Processors, it helps developers decouple their public API contracts from internal database entities, facilitating better API versioning and cleaner domain logic.

Key Features

01Creates validated Input DTOs with Symfony Constraints and entity mapping logic

02Generates immutable final readonly Output DTOs with static factory methods

030 GitHub stars

04Detects project namespaces and entity structures directly from your codebase

05Automatically updates #[ApiResource] attributes with correct input, output, and state classes

06Scaffolds custom State Providers and Processors to handle DTO-Entity transformation

Use Cases

01Decoupling API response structures from underlying database entity schemas

02Creating optimized read representations with calculated fields for specific API endpoints

03Implementing specialized validation logic for write operations without bloating entities
