FinlexLogger (@finlexlabs/logger)

Library Name: finlex-logger

Package Name: @finlexlabs/logger

Repo Name: fx-ng-components

Description:

There's a lot of risk in instantiating the logger outside of angular's DI that the logger updates it's dependencies and breaks your code.

The solution is to instantiate the logger using a class that supports Angular DI, and create a singleton that your non-angular files can use.

Import logger in any of the non-angular files you can just import the instance of NGXLogger.

When to use this module:

Only when the angular’s dependency is not available (e.g. model, a class outside angular, etc)

When not to use this module:

If the ngx-logger can be imported and instantiated using the normal Angular DI (e.g. components, services, pipes that have angular DI available).
