NatrHistorian

A logging library for Angular projects. This is done with decorators.

Install

npm install @natr/historian --save

or

yarn add @natr/historian

Usage

By default, log level is set to DEBUG. You can change this in environment{.*}?.ts

CurrentLogLevel.LOG_LEVEL = LogLevel.DEBUG;

export const environment = {
...
}

Then in a given class.

import {Logging} from '@natr/historian';

@Logging
@Component({
...
})
export class SomeComponent implements OnInit {
  logger: HistorianService;
  
  constructor() {
    this.logger.debug('wow, cool');
  }
} 

Not that there's some magic going on there. I'm not usually a fan of 'magic', but, here we are. Anyway, to get your typing to pass, you need to define a 'logger' property of HistorianService type, then it's automagically set for you, and away you go.
