lazysizes: Detailed Overview & Metrics
Lazysizes is a fast, feature-rich, and self-initializing lazy loader for images (including responsive images), iframes, and scripts. It helps optimize web page loading performance by deferring the loading of non-essential resources until they are needed, reducing initial page load time and saving bandwidth. Lazysizes automatically detects and handles various types of elements that can benefit from lazy loading, making it easy to implement lazy loading without extensive configuration.
Compared to other lazy loading libraries, Lazysizes stands out for its simplicity, flexibility, and extensive browser support. It offers a wide range of features like automatic polyfilling, support for responsive images, and seamless integration with popular front-end frameworks.
