AUTOWIRED SERVICES

AUTOWIRING ALLOWS TO REGISTER SERVICES IN THE CONTAINER WITH MINIMAL CONFIGURATION. IT AUTOMATICALLY RESOLVES THE SERVICE DEPENDENCIES BASED ON THE CONSTRUCTOR'S TYPEHINT WHICH IS USEFUL IN THE FIELD OF RAPID APPLICATION DEVELOPMENT, WHEN DESIGNING PROTOTYPES IN EARLY STAGES OF LARGE PROJECTS. IT MAKES IT EASY TO REGISTER A SERVICE GRAPH AND EASES REFACTORING. The Symfony Book AUTOWIRED SERVICES

THE ADR PATTERN

THE ADR PATTERN INTRODUCTION ▸ Stand for Action-Domain-Responder ▸ Web-specific refinement of Model-View-Controller https://github.com/pmjones/adr

THE ADR PATTERN DETAILS ▸ Action: logic that connects the Domain and Responder. Uses the request input to interact with the Domain, and passes the Domain output to the Responder. ▸ Domain: logic to manipulate the domain, session, application, and environment data, modifying state and persistence as needed. ▸ Responder: logic to build an HTTP response or response description. It deals with body content, templates and views, headers and cookies, status codes, and so on. Source: https://github.com/pmjones/adr

DUNGLASACTIONBUNDLE THE ROAD TO REUSABLE AND CROSS FRAMEWORK ACTIONS ▸ Don’t depend of FrameworkBundle features ▸ Use PSR-7 instead of HttpFoundation: https:// dunglas.fr/2015/07/slides-using-psr-7-with- symfony/ ▸ Don’t use annotations (prefer XML or YAML for routing)
