NGX Logger

NGX Logger is a simple logging module for angular (currently supports angular 5.*). It allows "pretty print" to the console, as well as allowing log messages to be POSTed to a URL for server-side logging.

Dependencies

• @angular/common
• @angular/core

Installation

npm install --save ngx-logger

Once installed you need to import our main module:

import { LoggerModule, NgxLoggerLevel } from 'ngx-logger';

The only remaining part is to list the imported module in your application module, passing in a config to intialize the logger.

@NgModule({
  declarations: [AppComponent, ...],
  imports: [LoggerModule.forRoot({serverLoggingUrl: '/api/logs', level: NgxLoggerLevel.DEBUG, serverLogLevel: NgxLoggerLevel.ERROR}), ...],
  bootstrap: [AppComponent]
})
export class AppModule {
}

Usage

To use the Logger, you will need import it locally, then call one of the logging functions

import { Component } from '@angular/core';
import { NGXLogger } from 'ngx-logger';

@Component({
  selector: 'your-component',
  templateUrl: './your.component.html',
  styleUrls: ['your.component.less'],
  providers: [NGXLogger]
})
export class YourComponent {
    constructor(private logger: NGXLogger) {
        this.logger.debug('Your log message goes here');
        this.logger.debug('Multiple', 'Argument', 'support');
    };
}

Config Options

• serverLogLevel - Only sends logs to the server for the level specified or higher (OFF disables the logger for the server)
• serverLoggingUrl - URL to POST logs
• level: The app will only log message for that level or higher (OFF disables the logger for the client)

TRACE|DEBUG|INFO|LOG|WARN|ERROR|OFF

Server Side Logging

If serverLogginUrl exists, NGX Logger will attempt to POST that log to the server.

Payload Example {level: 'DEBUG', message: 'Your log message goes here'}
