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)
