Welcome to the Ultimate Guide on ipc-logger

The ipc-logger library stands out as a powerful tool for IPC (Inter-Process Communication) and logging mechanisms. Leveraging this library can significantly improve efficiencies and streamline debugging for complex applications. In this guide, we introduce ipc-logger and walk you through dozens of useful APIs with practical code snippets. Let’s dive in!

Getting Started

First, ensure you have ipc-logger installed in your project:

  
    npm install ipc-logger
  

Basic Configuration

Initialize the logger with a basic configuration:

  
    const IPCLogger = require('ipc-logger');
    const logger = new IPCLogger({
      level: 'info',
      transport: 'file',
      filename: 'app.log'
    });
    logger.info('Logger initialized');
  

IPC Communication

Setting up basic IPC communication between processes:

  
    const { fork } = require('child_process');
    const child = fork('child.js');
    
    child.on('message', (message) => {
      logger.info('Received from child process:', message);
    });
    
    child.send('Hello from parent process');
  

In child.js:

  
    process.on('message', (message) => {
      logger.info('Received from parent process:', message);
      process.send('Hello from child process');
    });
  

Advanced Logging

Leveraging advanced logging features such as different levels and transports:

  
    const advancedLogger = new IPCLogger({
      level: 'debug',
      transports: ['file', 'console'],
      filename: 'advanced_app.log'
    });
    
    advancedLogger.debug('Debugging information');
    advancedLogger.error('An error occurred');
  

Custom Loggers

Creating custom loggers for different parts of your application:

  
    const customLogger = new IPCLogger({
      level: 'warn',
      transport: 'file',
      filename: 'custom_app.log',
      category: 'custom'
    });
    
    customLogger.warn('This is a warning from custom logger');
  

Building an Application with ipc-logger

Below is an example of a small application leveraging various APIs from ipc-logger:

  
    const express = require('express');
    const IPCLogger = require('ipc-logger');
    
    const app = express();
    const logger = new IPCLogger({
      level: 'info',
      transport: 'file',
      filename: 'server.log'
    });
    
    app.use((req, res, next) => {
      logger.info(`Request URL: ${req.url}`);
      next();
    });
    
    app.get('/', (req, res) => {
      logger.debug('Handling GET request for /');
      res.send('Hello, ipc-logger!');
      logger.info('Response sent: Hello, ipc-logger!');
    });
    
    app.listen(3000, () => {
      logger.info('Server is running on port 3000');
    });
  

In this example, we use ipc-logger for various logging levels and handling HTTP requests. This thorough monitoring approach can substantially aid in debugging and optimizing application performance.

In conclusion, ipc-logger is a versatile tool for improving communication and logging within applications. We hope this guide helps you get started and make the most of its functionalities.
