Image Processor - Node.js

Automate image optimization by converting image files to WebP format with ease. This module provides real-time directory watching, metadata logging, and customizable settings, all powered by Node.js. Perfect for developers looking to streamline image processing for web projects.

Features

• Convert to WebP: Automatically optimize images with customizable quality settings (default: 80).
• Real-Time Monitoring: Watch directories for new images and process them instantly.
• Metadata Display: Log image details like format, dimensions, and file size.
• Comprehensive Logging: Track actions and errors in both the console and a log file.
• Environment Variables: Fully customizable settings using a .env file.

Installation

1. Install via NPM
   Run the following command:

   npm install image-processor

2. Set Up Environment Variables
   Create a .env file in your project’s root directory to customize settings, such as image quality.
   Example .env file:

   IMAGE_QUALITY=90

Usage

1. Manual Execution

Run the image processor directly from the terminal:

node imageProcessor.js

This will:

• Convert existing images in the public/images directory to WebP format.
• Monitor the public/images directory for new images and process them automatically.

2. Importing as a Module

You can also import and use it in your own Node.js application:

const imageProcessor = require('image-processor');

// Start the processing and monitoring
imageProcessor.start();

Functions

• start()

  • Converts existing images in the directory.
  • Starts monitoring the directory for new image files.

• convertAndReplace(filePath)

  • Converts a single image to WebP format and replaces the original file.

• processExistingFiles()

  • Processes all existing files in the directory.

• startWatcher()

  • Watches the directory for new image files and processes them automatically.

Directory Structure

The default directory structure is:

/
├── public/
│   └── images/            # Directory containing the images to process
├── imageProcessor.js      # Main script
├── imageProcessor.log     # Log file
├── .env                   # Environment variables file
└── package.json           # Node.js project file

Logging

The module uses Winston for logging:

• Logs are displayed in the console.
• Logs are saved to a file named imageProcessor.log.

Troubleshooting

• Ensure the public/images directory exists and contains images.
• If you encounter permission issues, check the directory's file permissions.
• If images aren’t being processed, try deleting node_modules and reinstalling:

  rm -rf node_modules
  npm install
