DESCRIPTION
In this session we will discuss the theory behind ColdBox 4 Modules, how and when to use them, why they are important, and how they can change how you architect your applications. We will also look at the ins about outs of creating modules and discuss some of the challenges associated with building them. So if you are new to ColdBox Modules or if you have already started down the path of modular architecture, this session if for you.

EVOLVE TO MODULARITY
WHAT IS A MODULE?
"In structured design and data-driven design, a module is a generic term used to describe a named
and addressable group of program statements” by Craig Borysowich (Chief Technology Tactician)
!“A software module is a deployable, manageable, natively reusable, composable, stateless unit of
software that provides a concise interface to consumers.”
by Kirk Knoernschild
MODULAR ARCHITECTURE
• Break up a monolithic application • Individual logical parts that work in unison • Separation of concerns • Reusability concerns • Manageable dependencies
“As a system evolves, It’s complexity will increase unless work is done to maintain or reduce it.”
Lehman’s 2nd Law of software evolution
WHY MODULARIZE
• Represent separation of concerns • Creates logical boundaries and encapsulation • Provide behavior isolation • Improves maintainability • Improves reusability • Improves extensibility
COLDBOX MODULES
• Apply Modular Architecture • Module = A self-contained ColdBox application • Hierarchical MVC • Addressable • Composed • Dependencies • Runtime Installed • Reloaded • Unloaded

COLDBOX 4 - MODULES
• Everything became a module in ColdBox 4 • CommandBox CLI & Package Management • Modules Now Can:
• Automatically maps model objects with @namespace
• Execution aliases • Improved data/setting retrievals • Inception • Bundles • Dependencies • Register ColdFusion Mappings
Anatomy of a Module

handlers
layouts

modules
views
Module Name(unique on disk)
box.json
box.json
MODULECONFIG.CFC
• Simple CFC • Bootstraps your module • Must exist in the root of your module folder • Has public properties • configure() for configuration • 2 callback methods: onLoad(), onUnload() • Tier-detection enabled • It’s an interceptor too!

HOW IT WORKS?
• Download Source: https://github.com/Ortus-Solutions/ContentBox and install as a new site or a sub-folder in a site
• Create a database in your favorite database engine
• Create a datasource called “contentbox” in your CF admin that points to that database
• Hit your ContentBox install: http://localhost/index.cfm
Demo Time!
Thanks!
Go Modularize!
