lazy-image: A Next-Generation Image Processing Engine for Node.js

lazy-image is an advanced image processing engine designed for Node.js, focused on delivering smaller files with better quality and efficiency. Developed with a core in Rust and utilizing state-of-the-art compression technologies such as mozjpeg and AVIF, it ensures a balance between performance and memory efficiency.

Key Features

• Optimized File Sizes: Reduces image sizes significantly compared to traditional methods, achieving up to -9.7% smaller files for JPEG and -13.2% for complex pipelines when compared to similar libraries.
• Fast Processing Speeds: Processes images faster with improved throughput, for example, 1.06x faster for JPEG compression.
• Cross-Platform Compatibility: Works seamlessly across macOS, Windows, and Linux systems, accommodating various architectures including ARM and x64.
• Memory Efficiency: Employs a zero-copy architecture to minimize memory usage during image processing. This is particularly beneficial for batch processing applications.
• Comprehensive Format Support: Supports cutting-edge image formats such as JPEG, AVIF, WebP, and PNG, making it versatile for different use cases.

Usage

With a fluent API design, lazy-image facilitates straightforward image manipulation operations such as resizing, rotating, and format conversion. Here’s a simple JavaScript example for basic usage:

const { ImageEngine } = require('@alberteinshutoin/lazy-image');

const result = await ImageEngine.from('input.png')
    .resize(800, null) // Resize to width 800, auto height
    .rotate(90)        // Rotate by 90 degrees
    .toBuffer('avif', 60); // Convert to AVIF with quality 60

Why Choose lazy-image?

• Smaller Packages: Unlike other libraries that require large dependencies, lazy-image offers a total installation size between 6-9MB depending on the platform, which is significantly smaller than alternatives.
• Memory Safety: Built in Rust, it avoids common vulnerabilities like buffer overflows and memory leaks.
• Serverless Optimized: Designed for modern serverless environments, ensuring quick startup times and minimal resource consumption.
