Frictionless logger

Frictionless logger is a highly customizable logger with support for both production and development environments

Setting up the logger

import Logger, { FileSizeUnits, LoggerLevels } from 'frictionless-logger';

interface LoggerOptions {
  silent?: LoggerLevels[] | boolean;
  file?: LoggerFileOptions;
  notify?: LoggerNotifyOptions;
  message?: LoggerMessageOptions;
  showSourceFile?: ColorsEnum;
  colors?: boolean;
  name?: string;
}

const logger = new Logger({
  silent: true, // Stop the logger from printing to the console. Default is false
  file: {
    newLogFileFrequency: '12h', // How often the current logfile should be archived and a new log file to be created
    maxFileSize: {
      value: 10 // How large the log file should be before it is archived
      unit: FileSizeUnits.MB // size unit
    },
    zipArchive: true, // Should archived log files be zipped,
    dirname: 'logs', // The name of the logs folder
    absolutePath: 'C://user/desktop/logs', // The absolute path the logs folder should be created at
    filename: 'log', // The name of the current log file. Default is "current"
    extenstion: 'log' // What file extenstion should the log file have. Default is log
  },
  notify: { // Notify is optional. Leave it undefined if you dont want/need notifications
    levels: [LoggerLevels.Error], // What log level should trigger a notification. False for disabled which is default
    recipiants: ["[email protected]"],
    transport: Transporter, // Nodemailer transporter
    sender: "[email protected]", // Who is the sender of the email
    applicationName: "Name of your application", // This is used for the subject line in the email
  },
  message: {
    {
      // Static is a label in your log message where you can specify a static message. For example in your
      // authentication router you could have "Authentication" and it would print it in your logs
      static: {
        color: ColorsEnum.BrightGreen, // Color of the static message
        text: "Authentication" // The label name
      },
      level: {
        silly: Format, // Format follows the same format as static
        debug: Format,
        verbose: Format,
        http: Format,
        info: Format,
        warn: Format,
        error: Format,
      },
      timestamp: boolean,
      color: ColorsEnum, // The color your logs
    }
  },
  showSourceFile: ColorsEnum.Yellow, // ShowSourceFile will tell what the name of the file is where your log is comming from. Default is undefined
  colors: false, // Should colors be enabled or not. Default is true
}, true); // If true is passed as a second argument the config passed into the logger constructor will be saved for future initializations of the logger

// In the case the second argument is true the logger below will have the same config

const logger2 = new Logger();

Using the logger

const logger = new Logger();

logger.silly('silly message');
logger.debug('debug message');
logger.verbose('verbose message');
logger.http('http message');
logger.info('info message');
logger.warn('warn message');
logger.error('error message');

// In the case the logger is silenced but you still want a log to print to the console you cant pass an argument after your message
logger.info('This log is really important', {
  notify: true, // This will send an email notification to the desired recipiants
  force: true, // This will force the log to the terminal if you have silenced the logger
});

Advanced logger configuration

import Logger from 'frictionless-logger';

const config = {
  file: {
    newLogFileFrequency: '12h', // How often the current logfile should be archived and a new log file to be created
    maxFileSize: {
      value: 10 // How large the log file should be before it is archived
      unit: FileSizeUnits.MB // size unit
    },
    zipArchive: true, // Should archived log files be zipped,
    dirname: 'logs', // The name of the logs folder
    absolutePath: 'C://user/desktop/logs', // The absolute path the logs folder should be created at
    filename: 'log', // The name of the current log file. Default is "current"
    extenstion: 'log' // What file extenstion should the log file have. Default is log
  }
}

const logger1 = new Logger(); // Will not have global config


// This will save as a global config which will initialize on all new loggers
new Logger(
  Logger.combine( // Deep merge of objects
    config,
    {
      notify: {
        levels: [LoggerLevels.Error],
        recipiants: ["[email protected]"],
        transport: Transporter,
        sender: "[email protected]",
        applicationName: "Name of your application",
    }
}), true);


const logger = new Logger(); // Has global config
