It is designed to work with Confluent Platform for a robust and scalable log management solution. This blog will introduce you to the Confluent Logger and provide useful API explanations along with code snippets to get you started.

Getting Started with Confluent Logger

First, you need to install the Confluent Logger package. You can do this using npm or yarn:

 npm install confluent-logger

 yarn add confluent-logger

Useful APIs and Code Snippets

1. Basic Configuration

Initialize the Confluent Logger with basic configurations:

 
  const ConfluentLogger = require('confluent-logger');
  
  const logger = new ConfluentLogger({
    brokers: ['localhost:9092'],
    clientId: 'my-app',
    level: 'info'
  });
 

2. Logging Messages

Log messages with different levels of severity:

 
  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. Structured Logging

Log structured data for better insights:

 
  logger.info({
    event: 'user_signup',
    user: 'john_doe',
    timestamp: Date.now()
  });
 

4. Using Middleware

Integrate Confluent Logger middleware in your Express.js application:

 
  const express = require('express');
  const app = express();
  
  app.use(logger.middleware());
  
  app.get('/', (req, res) => {
    res.send('Hello World');
  });
  
  app.listen(3000, () => {
    console.log('Server is running on port 3000');
  });
 

5. Custom Transports

Create custom transports to manage log outputs:

 
  logger.addTransport(new ConfluentLogger.Transport.File({
    filename: 'app.log',
    level: 'debug'
  }));
  
  logger.addTransport(new ConfluentLogger.Transport.Console());
 

Full Example Application

Below is a full example of an Express.js application integrated with Confluent Logger:

 
  const express = require('express');
  const ConfluentLogger = require('confluent-logger');
  
  const app = express();
  const logger = new ConfluentLogger({
    brokers: ['localhost:9092'],
    clientId: 'my-app',
    level: 'info'
  });
  
  app.use(logger.middleware());
  
  app.get('/', (req, res) => {
    logger.info('Home page requested');
    res.send('Hello World');
  });
  
  app.listen(3000, () => {
    logger.info('Server is running on port 3000');
  });
