Introduction to Jumbo Logger

Jumbo Logger is a powerful logging library designed for developers who seek efficiency and customization. It offers a wide range of APIs to meet diverse logging needs. Below, we explore some of its most useful APIs with practical code snippets.

API Examples

Basic Configuration

Setting up Jumbo Logger is straightforward. Here’s a simple example to get started:

  const JumboLogger = require('jumbo-logger');
  const logger = new JumboLogger();

Logging Messages

Log messages with different levels:

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

Custom Log Levels

Create custom log levels to suit your application’s needs:

   logger.addLevel('debug', 500, { color: 'blue' });
   logger.debug('This is a debug log');

Log to Multiple Destinations

Jumbo Logger can log to various destinations such as files, databases, or APIs:

   logger.addDestination('file', { filename: 'app.log' });
   logger.addDestination('db', { connectionString: 'mongodb://localhost:27017/logs' });

Conditional Logging

Log messages based on conditions:

   logger.setCondition('warn', (msg) => {
     return msg.includes('specific keyword');
   });

Error Handling

Gracefully handle and log errors:

   try {
     // some code that may throw an error
   } catch (err) {
     logger.error('An error occurred', err);
   }

App Example

Here’s an example of a simple Node.js application using Jumbo Logger:

   const JumboLogger = require('jumbo-logger');
   const express = require('express');
   const app = express();
   const logger = new JumboLogger();
   
   logger.addLevel('debug', 500, { color: 'blue' });
   
   app.use((req, res, next) => {
     logger.info(`Request received: ${req.method} ${req.url}`);
     next();
   });
   
   app.get('/', (req, res) => {
     logger.debug('Handling root endpoint');
     res.send('Hello, world!');
   });
   
   app.use((err, req, res, next) => {
     logger.error('An error occurred', err);
     res.status(500).send('Internal Server Error');
   });
   
   app.listen(3000, () => {
     logger.info('Server is running on port 3000');
   });

With these examples, you are well on your way to mastering Jumbo Logger. Happy logging!
