Reusability Of Symfony Component - Mindworks

Posted by artodeto on Wednesday, October 9. 2013

Take a look to knpbundles.

Hurdles

problem is solved in other language
problem is solved in other licence
can be solved by design patterns (abstract solution)
write a good bundle/component that is general enough takes much more time

Anti-Pattern

Reuseage by copy and paste.

decreases maintainability
decreases testability
violates dry principle

Scenario

community web application
users seek other users by interests
how to input data to easy up matching?

What Do We Need?

form widget (js and css based)
data transformer (converts format from storage to human readable presentation and back)
form type (provides name for form widget, called in FormTypes, gets TagManager injected and defines DataTransformer)
Entity Trait (avoid copy and paste)
Taggable Subscriber
Make it reusable (dedicated bundle, created composer project)
Use JavaScript and CSS via "composer component" (see web/bundles, RobLoach/component-installer)
