Introduction to Moment Logger

Moment Logger simplifies the process of tracking and recording events in your application. Whether you need detailed logs for debugging or just want to keep a record of user actions, Moment Logger has you covered.

Basic Setup

  
    // Install the library
    npm install moment-logger

    // Import the library
    import MomentLogger from 'moment-logger';

    // Initialize the logger
    const logger = new MomentLogger();
  

APIs and Examples

1. Log Messages

  
    // Log an info message
    logger.log('info', 'Application started');

    // Log a warning message
    logger.log('warn', 'Deprecated function called');

    // Log an error message
    logger.log('error', 'An error occurred');
  

2. Set Log Level

  
    // Set the log level to 'debug'
    logger.setLogLevel('debug');

    // Now only messages of debug level and above will be logged
    logger.log('debug', 'Debugging info');
  

3. Custom Log Formats

  
    // Set a custom log format
    logger.setFormat(({ level, message, timestamp }) => {
      return `${timestamp} [${level.toUpperCase()}] - ${message}`;
    });

    logger.log('info', 'Custom formatted log message');
  

4. Log with Context

  
    // Log a message with additional context
    logger.log('info', 'User logged in', { username: 'johndoe', role: 'admin' });

    // Log an error with stack trace
    try {
      // Code that throws an error
    } catch (error) {
      logger.log('error', 'Unhandled exception', { error });
    }
  

Sample Application

  
    import MomentLogger from 'moment-logger';

    const logger = new MomentLogger();

    function startApp() {
      logger.log('info', 'Starting the application');

      try {
        // Application logic here
        logger.log('info', 'Application is running');
      } catch (error) {
        logger.log('error', 'Application crashed', { error });
      }
    }

    // Start the application
    startApp();
