About

@barry-bot/logger is a powerful logger package that provides a flexible and customizable logging solution for Node.js applications. It offers various features such as log severity levels, error handling, log formatting, and integration with Sentry for error reporting.

Features

  • Log Severity Levels: Log messages with different severity levels such as DEBUG, ERROR, FATAL, INFO, TRACE, and WARN.
  • Sentry Integration: Integrate with Sentry for advanced error tracking and reporting.
  • Flexible Configuration: Customize the logger options to control log behavior, minimum severity level, date display, and more.
  • Log Formatting: Format log messages using printf-style string interpolation.
  • Colorful Output: Log messages are displayed with colors based on their severity level for easy visual identification.

Installation

Node.js version 20 or later is required.

npm install @barry-bot/logger
# or
yarn add @barry-bot/logger

Example Usage

import { Logger, LogSeverity } from "@barry-bot/logger";

// Create a new logger instance.
const logger = new Logger({
    minSeverity: LogSeverity.INFO,
    showDate: true,
    sentry: {
        dsn: "YOUR_SENTRY_DSN",
        minSeverity: LogSeverity.Error
    }
});

// Log messages with different severity levels.
logger.trace("This is a trace message");
logger.debug("This is a debug message");
logger.info("This is an info message");
logger.warn("This is a warning message");
logger.error("This is an error message");
logger.fatal("This is a fatal message");

// Log formatted messages using printf-style string interpolation.
logger.info("Hello %s", "World");

// Log an error.
const error = new Error("Oh no!");
logger.fatal("An error has occurred:", error);
