Reliable Logger: The Ultimate Logging Solution for Your Applications

Welcome to the world of reliable-logger – the most efficient and effective tool for handling all your logging requirements. In this article, we will introduce the reliable-logger, its various APIs with code snippets, and a sample application to demonstrate its integration and usage.

Introduction

reliable-logger is a powerful logging library designed to provide robust and scalable logging capabilities. Keeping track of log messages is essential for debugging, monitoring, and maintaining applications. With reliable-logger, you can easily log information, warnings, errors, and debug messages with ease and flexibility.

APIs and Code Snippets

Here are some of the most useful APIs provided by reliable-logger along with code snippets to demonstrate their usage:

1. Initializing the Logger

 const logger = require('reliable-logger').createLogger({
   level: 'info',
   transports: [
     new require('reliable-logger').transports.Console(),
     new require('reliable-logger').transports.File({ filename: 'app.log' })
   ]
 });

2. Logging Messages

Log different types of messages like info, warn, error, and debug.

 logger.info('This is an info message');
 logger.warn('This is a warning message');
 logger.error('This is an error message');
 logger.debug('This is a debug message');

3. Adding Metadata to Logs

You can attach additional metadata to your log messages.

 logger.info('User logged in', { userId: '12345' });

4. Customizing Log Levels

Define custom log levels for more granular control.

 logger.addLevels({
   customLevel: 0
 });
 logger.customLevel('This is a custom level message');

5. Asynchronous Logging

Ensure non-blocking log operations.

 await logger.async.info('This message is logged asynchronously');

Sample Application

Below is an example of a simple application that integrates reliable-logger to demonstrate its capabilities:

 const express = require('express');
 const logger = require('reliable-logger').createLogger({
   level: 'info',
   transports: [
     new require('reliable-logger').transports.Console(),
     new require('reliable-logger').transports.File({ filename: 'app.log' })
   ]
 });
 
 const app = express();
 
 app.use((req, res, next) => {
   logger.info('Incoming request', { method: req.method, url: req.url });
   next();
 });
 
 app.get('/', (req, res) => {
   res.send('Hello, world!');
   logger.info('Response sent');
 });
 
 app.listen(3000, () => {
   logger.info('Server is running on port 3000');
 });

With the above example, you can see how easy it is to integrate reliable-logger into your application and start logging important messages right away.
