Hastily: Fastly Image Optimization for Express

Hastily is an Express.js middleware designed to replicate the functionality of the Fastly Image Optimization API directly within your Node.js application. It enables on-the-fly image transformations and optimizations by parsing Fastly-compatible URL parameters and applying them to images served by an existing Express static server or image-serving middleware. This allows developers to integrate powerful image manipulation capabilities without relying on an external CDN service for basic optimizations. The package is currently at version 0.5.0, indicating pre-1.0 development where minor version bumps might introduce breaking changes. Its key differentiators include its drop-in compatibility with Express, leverage of the high-performance `sharp` library for image processing, and its focus on mimicking the Fastly API for familiar usage patterns.
