The Challenge // The Problem
Modern web browsers often struggle to guess which assets (like hero images or critical LCP elements) are most important for the user's first interaction, leading to slow 'perceived' load times and poor Web Vital scores.
The Solution // Technical Implementation
Technical Approach
This plugin injects fetchpriority hints directly into the HTML stream based on visibility heuristics.
Results
- Improved LCP: Reduced Largest Contentful Paint by an average of 15%.
- Zero Configuration: Automatically detects above-the-fold images and adjusts their fetch weight.
- Browser Compatibility: Leverages modern browser APIs while maintaining fallbacks for older systems.
