Services

Overview

Services are "concern-specific" code modules that can be consumed across layers. Services provide a set of operations, often tied to some shared state, and are made available to through out the app via the ServicesManager. Services are particularly well suited to address cross-cutting concerns.

Each service should be:

• self-contained
• able to fail and/or be removed without breaking the application
• completely interchangeable with another module implementing the same interface

In OHIF-v3 we have added multiple non-UI services and have introduced pub/sub pattern to reduce coupling between layers.
