How do I handle circular references in API Platform?

Use the MaxDepth attribute on your entity properties and enable 'enable_max_depth' in the normalization context to prevent infinite recursion during serialization.

How do I restrict certain fields to admin users only?

Implement a Context Builder to dynamically add an 'admin:read' group to the serialization context if the current user has the 'ROLE_ADMIN' permission.

Can I add fields to an API response that aren't in my database?

Yes, you can use Custom Normalizers to inject computed fields or use the Serializer's context to add dynamic data during the normalization process.

What is the best practice for naming serialization groups?

It is recommended to use a consistent 'entity:operation' convention, such as 'user:read' for GET operations and 'user:create' for POST operations.

Desarrollo de API

Manages API data transformation and visibility using serialization groups, custom normalizers, and dynamic context builders in Symfony.

Acerca de

This skill provides comprehensive patterns for controlling how PHP entities are transformed into JSON or XML formats within Symfony's API Platform. It guides developers through implementing granular access control via serialization groups, adding computed fields through custom normalizers, and managing complex object relations with max-depth settings. By leveraging these patterns, developers can ensure secure data exposure, optimize payload sizes, and handle dynamic requirements like role-based field visibility, ensuring a professional and secure API architecture.

Características Principales

Dynamic serialization context builders for role-based and ownership-based data visibility
21 GitHub stars
Granular control over API output using operation-specific serialization groups
Circular reference prevention using MaxDepth and circular reference handlers
Custom normalizers for adding computed fields and logic-based data transformations
Clean separation of read and write contexts to handle input/output requirements independently

Casos de Uso

Including calculated data such as full names or aggregate counts in API responses without polluting database entities
Hiding sensitive fields like passwords or internal notes from public API endpoints based on user roles
Managing complex entity relationships to prevent deep nesting and improve API performance
