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-v3we have added multiple non-UI services and have introduced pub/sub pattern to reduce coupling between layers.
