Introduction to RabbitMQ Logger

RabbitMQ Logger is a robust logging library designed to provide comprehensive logging functionalities for applications utilizing RabbitMQ. It simplifies the process of capturing and storing logs, enabling developers to monitor and troubleshoot their RabbitMQ-based systems efficiently.

Key Features

• Easy integration with RabbitMQ.
• Flexible and customizable logging levels.
• Supports multiple output formats (JSON, Plain text).
• Enhanced performance with asynchronous logging.

API Overview

Initialization

    const logger = require('rabbitmq-logger');
    const log = new logger({
        host: 'localhost',
        port: 5672
    });

Basic Logging

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

Advanced Logging

    log.debug('This is a debug message');
    log.verbose('This is a verbose message');
    log.silly('This is a silly message');

Custom Logging Levels

    log.log({
        level: 'custom',
        message: 'This is a custom level log message'
    });

Logging with Metadata

    log.info('User logged in', { userId: 123, username: 'johndoe' });

JSON Format Logging

    log.info('This log will be in JSON format', {
        format: 'json'
    });

Asynchronous Logging

    log.async('This is an asynchronous log message', async () => {
        // Do some async operations
    });

Application Example

    const logger = require('rabbitmq-logger');
    const log = new logger({
        host: 'localhost',
        port: 5672
    });

    app.post('/login', (req, res) => {
        const { username, password } = req.body;

        log.info('Login request received', { username });

        authenticateUser(username, password)
            .then(user => {
                log.info('User authenticated', { userId: user.id });
                res.status(200).send(user);
            })
            .catch(err => {
                log.error('Authentication failed', { username, error: err.message });
                res.status(401).send({ error: 'Authentication failed' });
            });
    });

Through these examples, you can see how RabbitMQ Logger can be a valuable tool in maintaining and debugging RabbitMQ applications. Its comprehensive API allows for precise and effective log management, ensuring that all necessary information is captured and easily accessible.
