• Everything is a module

• A module has one single purpose (no “Helper” or “Utility” modules)

• Modules are kept separated from each other (High Cohesion/Low Coupling)

• A module is self contained

• A module is as stable as possible

Modules


“The granule of reuse is the granule of release”https://en.wikipedia.org/wiki/Package_principles

• What belongs together is maintained and released together

• A module contains all types of data that are applicable to the module:

• Code

• Configuration

• Templates

• Renderings

• Items

Modules

https://en.wikipedia.org/wiki/Package_principles


“Classes that change together, belong together”https://en.wikipedia.org/wiki/Package_principles

• Define what belongs to a single module.• Minimize the risk of a change influencing the module

• The Habitat architecture is pointless without this

• Features output semantic HTML

• Site-specific styling belongs in the Project layer

• Only include files that belong to the module. Do not include out-of-the-box Sitecore files or other dependencies

Modules

• Levels of stability

• The closer to the Foundation layer, the more stable

• The more stable the module, the more abstract

Layers


“The abstractness of a package should be in proportion to its stability”https://en.wikipedia.org/wiki/Package_principles

Layers



Layers


“Depend in the direction of stability”https://en.wikipedia.org/wiki/Package_principles

• Project Layer -> Features Layer -> Foundation Layer

• Changes on a lower level layer have more impact and require more tests

• In order to maintain productivity, we must be able to trust the Foundation layer

Layers



Project layer modules

• Only website modules

• Very concrete and specific to the solution

• Can contain styling (CSS and design Javascript)

• No functional Javascript

• No business logic

Foundation layer modules

• API only

• High level of abstraction

• No references to the Features or Project layer

• Does not contain presentation

Features layer modules

• No references to the Project layer

• Avoid references to other Features layer modules

• No styling (CSS and design Javascript)

• Can contain functionalJavascript

• Outputs semantic HTML

• Contains configuration that is specific to the module

Layers


Cool:

• Solid architecture

• Easy to understand

• Future proof, designed for growth

• Community support

Not so cool:

• Conventions / reasoning not (fully) documented

• Build system

• Early days (stability)

• Not upgradable
