Does it support modern Symfony features?

Yes, it leverages modern features like PHP 8 attributes, MapRequestPayload, and the Symfony Messenger component for asynchronous tasks.

How does it handle security logic?

It extracts complex access control logic from the controller into dedicated Symfony Voters, making authorization more robust and reusable.

What is a 'fat controller' in Symfony?

A fat controller is one that contains excessive logic such as database queries, business rules, and validation instead of just orchestrating the request and response.

How does this skill improve application testing?

By moving logic into services and DTOs, it allows you to write lightweight unit tests for business rules without the overhead of the full HTTP stack.

Will my API routes change during refactoring?

No, the skill is designed to refactor the internal implementation while preserving the existing routing structure and response formats.

API Development

Refactors bloated Symfony controllers into clean, maintainable code by extracting business logic into services and DTOs.

This skill helps developers transform complex 'fat' Symfony controllers into 'lean' controllers by adhering to best practices and the Single Responsibility Principle. It identifies business logic, validation, and authorization within controller actions and automates their extraction into dedicated services, Data Transfer Objects (DTOs), and Symfony Voters. By streamlining request handling and offloading side effects to asynchronous messages, it significantly improves code maintainability, reduces technical debt, and makes your application easier to unit test.

Key Features

01Implements validated Data Transfer Objects (DTOs) for request payloads

02Offloads authorization checks to custom Symfony Voters

03Transition side effects to asynchronous messages using Symfony Messenger

04Extracts complex business logic into dedicated, reusable service classes

05Configures MapRequestPayload and ParamConverter for modern input handling
