If you, in fact, can not speak - then you 'have' to write!

Logging is for you!

Logging library for writing to and exporting from local storage. Can also be used to log to Google Analytics, the console, and it's expandable.

Made for Angular 4+ compatibility. Maintained by niikoo for use with:

What is it?

This TypeScript library for Angular 4+ provides a mechanism to log to local storage and export the most recent entries. It will overwrite the oldest entries when writing a new entry if adding the entry makes the log bigger than maxLogSizeInBytes.

Installation

npm install --save ng-alogy

Usage

This is how you can use the logging functionality:

Add the module in app-module.ts or another module to use it as injectable service.

This example is based on that:

import { Injectable } from '@angular/core';
import { Alogy } from 'ng-alogy';

@Injectable()
export class LogService {
  constructor(
  	private _alogy: Alogy
  ) {
    this._alogy.create(
      AlogyLogDestination.LOCAL_STORAGE,
      <ILocalStorageLoggerConfiguration>{
        logName: 'testLog', // Log name
        maxLogSizeInBytes: 2^20 // Log size - in bytes
    });
  }
  
  /**
   * Logging interface, logging in a specific logging group.
   * 
   * @param {number} logGroup The log group ID number (for example: 3 or 5)
   * @returns 
   * @memberof LogService
   */
  getLoggingInterface(logGroup: number) : ILog {
    return this._alogy.getLogAPI(
      logGroup,
      AlogyLogDestination.LOCAL_STORAGE
    );
  }
}

Then, from whatever component or service you'd like:

import { LogService } from './log.service'
import { ILog } from 'ng-alogy';

export class Example {
  private _log: ILog;
  constructor(
  	private _logService: LogService
  ) {
    this.log = this._logService.getLoggingInterface(15); //15 as an example group
  }

  isItTrue(test:boolean):void {
    if(test) {
      this._log.info('it is true');
    } else {
      this._log.error('it is not true');
    }
  }
}
