Introduction to 0db-logger

The 0db-logger is a versatile and efficient logging library designed for Node.js applications. It offers a wide range of features and APIs to help developers implement robust logging mechanisms quickly and effortlessly.

Getting Started with 0db-logger

First, you need to install the 0db-logger package in your Node.js application:

npm install 0db-logger

Basic Usage

Here is a simple example to get started with 0db-logger:

const Logger = require('0db-logger');
const logger = new Logger();

logger.info('This is an informational message');
logger.error('This is an error message');

Advanced Configuration

0db-logger allows advanced configurations to customize the logging behavior:

const Logger = require('0db-logger');

const config = {
  level: 'debug',
  transports: [
    'console',
    {
      type: 'file',
      filename: 'app.log',
      maxSize: 1000000
    }
  ]
};

const logger = new Logger(config);

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

Custom Transports

Create and use custom transports for logging:

const Logger = require('0db-logger');

class CustomTransport {
  log(level, message) {
    // Implement custom logging logic
    console.log(`[${level.toUpperCase()}]: ${message}`);
  }
}

const config = {
  transports: [new CustomTransport()]
};

const logger = new Logger(config);
logger.info('This is a message with custom transport');

Using Middleware

Integrate 0db-logger with Express for HTTP request logging:

const express = require('express');
const Logger = require('0db-logger');

const app = express();
const logger = new Logger();

app.use(logger.middleware());

app.get('/', (req, res) => {
  res.send('Hello, World!');
});

app.listen(3000, () => {
  logger.info('Server is running on port 3000');
});

Application Example

Below is an example application that utilizes the discussed APIs:

// app.js
const express = require('express');
const Logger = require('0db-logger');

const app = express();
const logger = new Logger({
  level: 'debug',
  transports: [
    'console',
    {
      type: 'file',
      filename: 'app.log',
      maxSize: 500000
    }
  ]
});

app.use(logger.middleware());

app.get('/', (req, res) => {
  logger.info('Root endpoint hit');
  res.send('Logging with 0db-logger!');
});

app.listen(3000, () => {
  logger.debug('Application is running on http://localhost:3000');
});

By following this guide, you can effectively implement and utilize 0db-logger in your Node.js applications for better logging and debugging capabilities. Enhance your application’s maintainability and performance with efficient logging practices.
