Recently, I did a webinar on Refactoring Legacy Code and the question came up about whether or not it was possible to use ColdBox with existing code without converting everything to a ColdBox module or making changes to the existing codebase. In the first installation in this series, we took a tour of the various elements which make up ColdBox. In the second installation, we looked at creating layouts, views, and routes in the main site. In the third, we created a module and did the first integration of our existing code into our ColdBox site. In the fourth, we continued developing our module with a handler and passing variable back to Coldbox. Now we'll use Wirebox with and without ColdBox Modules to see how these approaches differ from a traditional approach.
