Single Logger

single-logger is a lightweight Node.js logging utility designed to provide simple event logging capabilities. It helps you manage logs in a structured manner and facilitates easy integration into your Node.js applications.

Installation

You can install single-logger using npm:

npm install single-logger

Usage

importing the module

First, import the logger module into your Node.js application:

const logger = require("single-logger");

Logging Events

To log events using single-logger, you can call the 'logEvent functuion:

logger.logEvent(event, level, message);
  • 'event': A descriptive label for the event being logged.

  • level: The severity level of the event (e.g., "INFO", "WARNING", "ERROR").

  • message: The message or details associated with the event.

example:

const event = "app";
const level = "INFO";
const message = "GET request received";
logger.logEvent(event, level, message);

Integration with Event Emitter

single-logger can be integrated with Node.js' built-in Event Emitter or other event-driven architectures for streamlined event logging.

Example integration with Event Emitter:

const events = require("events");
const emitEvent = new events.EventEmitter();

// Define a listener for your events
emitEvent.on("log", (event, level, message) => {
  logger.logEvent(event, level, message);
});

// Emit an event
emitEvent.emit("log", "app", "INFO", "GET request received");

Configuration

You can configure certain aspects of single-logger by modifying the code according to your needs. The following aspects can be customized:

  • log formatting: The way log messages are structured, including the date format and fields order.

  • log directory: The directory structure where log files are stored. By default, logs are saved in the logs/YYYY/MM/ directory structure.

Please refer to the source code for detailed information on how to customize these aspects.
