guess-js/guess

Leverages Google Analytics data to build predictive navigation models that automatically optimize bundle splitting and prefetching strategies in Webpack, or enable client-side resource prediction for static sites. The core architecture parses framework routes, queries GA API for user transition probabilities, and uses those patterns to determine which code chunks or pages to prefetch based on connection speed and navigation likelihood. Supports both bundler-level optimization through the GuessPlugin and lightweight predictive-fetching for non-bundled sites.
