I maintained then, and do now, that a “factory” always-and-only returns a new instance. If you have a “factory” that returns anything other than a new instanc... Radar: A PSR-7 Action-Domain-Responder Framework 2015-05-19T10:00:58-05:00 Radar is a PSR-7 compliant Action-Domain-Responder (ADR) system. While it may look like a micro-framework, it is more like a wrapper around the real core of your application domain. Its architecture makes it an excellent complement to Domain Driven D... MVC and ADR are User-Interface Patterns, Not Application Architectures 2015-01-21T09:54:31-06:00 N.b.: I am the author of the Action-Domain-Responder paper referenced in this article. In his post on MVC alternatives (including Action-Domain-Responder), Anthony Ferrara makes a claim that is central to his discussion. While I agree with much he s... What's The Difference Between A "Pivot Table" And An "Association Table"? 2014-10-09T06:43:29-05:00 An “association table” is a table that joins other tables in a many-to-many relationship.

What's The Difference Between Tightly-, Loosely-, and De-Coupled ? 2014-10-06T07:00:02-05:00 In a tweetstorm that spun up late last week, Taylor Otwell produced the following commentary: look guys I’m “decoupled” because this package doesn’t have composer dependencies!!! HAHAHAHA LOL how many composer packages a given pa... Action-Domain-Responder and the "Domain Payload" Pattern 2019-12-10T11:08:00-06:00 tl;dr: Instead of inspecting a Domain result to determine how to present it, consider using a Domain Payload Object to wrap the results of Domain interaction and simulataneously indicate the status of the attempted interaction. The Domain already kno... Action-Domain-Responder, Content Negotiation, and Routers 2014-07-17T11:55:08-05:00 While talking about Action-Domain-Responder on the Crafting Code Tour, one of the common questions I got was: "Where does content negotiation happen?" My response was always: "Where does it happen in Model-View-Controller?" That opened up a discuss... Refactoring To Action-Domain-Responder 2014-06-05T10:20:50-05:00 The v1 version of the Aura framework includes a controller to handle web assets. The idea for this controller was that an Aura package might have images, scripts, and stylesheets that need to be publicly available, but in development you don't necess... The Template Is Not The View 2014-05-26T11:23:18-05:00 As server-side web developers, we tend to think of our templating system as providing the View layer in a Model-View-Controller architecture. I have recently come to the conclusion that this is an incorrect approach. Instead, we need to think of th... Stephan Hochdörfer and Action-Domain-Responder 2014-05-19T11:10:18-05:00 I've been asking for feedback on the Action-Domain-Responder pattern, a refinement of MVC, to discover how it's being used in the wild already, and to solicit criticism of the pattern to find weak points. The key points of Action-Domain-Responder: ...
