Eleventy High Performance Blog
This project is a pre-configured static site template and web performance starter for building blogs using the Eleventy static site generator. It provides a foundation for creating high-performance websites through an automated build pipeline that transforms templates and content into optimized HTML files.
The framework distinguishes itself by implementing a strict security posture using hash-based content security policies and a privacy-centric analytics setup that proxies tracking requests through edge functions. It further emphasizes performance through the localization of remote images and the serving of web fonts from the local origin to prevent layout shifts.
The project covers comprehensive capabilities for media optimization, including the generation of multiple image formats and blurry placeholders. It includes built-in systems for SEO and social metadata management, XML sitemap generation, and the automated creation of RSS feeds and paginated content archives. Asset delivery is further optimized through CSS minification and immutable caching headers.
