    Class Logger

    Represents a logger that can be used to log messages with different severity levels.

    Change the static level property to change the severity level of messages that are logged.

    Change the static transports property to change the way messages are logged.

    Use Logger.ignore to ignore a severity level.

    const logger = new Logger("MyLogger");
    Logger.level = LogLevel.DEBUG;
    Logger.transports = { debug: print, info: print, warn: print, error: print };

    Methods

    • Logs a debug message.

      Debug messages are less verbose than trace messages and should be used for debugging.

      Parameters

      • message: string

        The message to be logged.

      Returns void

      const logger = new Logger("MyLogger");
      logger.debug("This is a debug message");

    • Logs an error message.

      Error messages are the least verbose and should be used for logging errors.

      Parameters

      • message: string

        The message to be logged.

      Returns void

      const logger = new Logger("MyLogger");
      logger.error("This is an error message");

    • Logs an info message.

      Info messages are less verbose than debug messages and should be used for logging information.

      Parameters

      • message: string

        The message to be logged.

      Returns void

      const logger = new Logger("MyLogger");
      logger.info("This is an info message");

    • Logs a trace message.

      Trace messages are the most verbose and should only be used for debugging.

      Parameters

      • message: string

        The message to be logged.

      Returns void

      const logger = new Logger("MyLogger");
      logger.trace("This is a trace message");

    • Logs a warning message.

      Warning messages are less verbose than info messages and should be used for logging warnings.

      Parameters

      • message: string

        The message to be logged.

      Returns void

      const logger = new Logger("MyLogger");
      logger.warn("This is a warning message");

    • A transport function that does nothing.

      Use this to ignore a severity level as an alternative to setting the LogLevel, this can be useful where for example the trace transport is enabled but sending to an alternative location, but you want to disable info.

      Returns void

      const logger = new Logger("MyLogger");
      logger.transports = { debug: Logger.ignore, info: Logger.ignore, warn: print, error: print };
