ForesightJS is a lightweight, framework-agnostic JavaScript library that predicts user intent from mouse trajectory, keyboard navigation, scroll, and touch cues to trigger prefetching before a user reaches a link or element. It ships official integrations for React, Vue, Angular, and Astro, plus devtools for visual debugging.
Use cases
- prefetch links before the user hovers them
- predict user intent from mouse movement
- prefetch on keyboard tab navigation
- smart prefetching for mobile touch devices
- reduce perceived page load times
- prefetch content when user scrolls toward an element
- respect data-saver and slow connections when prefetching
When to choose
- you want intent-based prefetching that works out of the box with zero configuration
- you need framework-agnostic prefetching with official React, Vue, Angular, or Astro adapters
- you want to support both desktop (mouse/keyboard) and mobile (touch/viewport) prediction strategies
- you need to avoid wasting bandwidth on slow connections or data-saver mode
When to avoid
- you only need simple hover or click prefetching without intent prediction
- your app is not browser-based (e.g., server-side or native-only)
- you cannot tolerate any client-side JavaScript overhead for tracking user input
