PieLogger

PieLogger is a feature-rich, customizable, and lightweight logger for Node.js applications. It supports multiple log levels, structured logging, colored console output, and file-based logging.

Installation

Install the package using npm:

npm install pie-logger

Usage

1. Basic Setup

import { PieLogger } from "pie-logger";

const logger = new PieLogger({ loggerName: "MyAppLogger" });

logger.info("This is an info message.");
logger.error("This is an error message.", { error: "Sample Error" });

2. Available Log Levels

Example:

logger.debug("Debugging a process.");
logger.info("This is an informational message.");
logger.warning("This is a warning message.");
logger.error("This is an error message.", { errorCode: 500 });
logger.critical("Critical failure!", { service: "Database" });

3. Configuration Options

You can customize PieLogger with several configuration options:

const logger = new PieLogger({
  loggerName: "MyAppLogger", // Name of the logger
  logToFile: true, // Enable/Disable file-based logging (default: true)
  logDirectory: "logs", // Directory for log files (default: 'logs')
  minimumLogLevel: PieLogLevel.DEBUG, // Minimum log level (default: INFO)
  colorful: true, // Enable colored console output (default: true)
});

4. Structured Logging

PieLogger supports structured logging with additional details:

logger.info("User logged in", { userId: 123, action: "login" });
logger.error("Error processing request", {
  endpoint: "/api/data",
  errorCode: 400,
});

5. File Logging

Logs are automatically saved to files when logToFile is enabled. Files are rotated when they reach the size limit (32MB by default).
