README

Create REST APIs with just a few lines of Expressive config. This PSR7 compliant PHP library that uses Zend\Expressive Middleware config at its core.

• Allows creation of API end points using only config for Doctrine entities
• Allows configuration of common API concerns:
  • data-extractor - Getting arrays from data objects and object arrays
  • data-hydrator - Getting data from client into data objects and arrays
  • data-validate - Validating data from client
  • repository - Common repository methods
  • request-attributes - Common query params ('where', 'fields', 'limit', 'order', 'skip', etc...)
  • request-attributes-validate - Validate the params
  • request-format - Data format parsing the request data
  • response-format - Data format for response (JSON, etc...)
  • response-headers - Common headers for response (caching etc...)
