Vite

A comprehensive performance optimization guide for Vite with 42 rules across 8 priority-ranked categories, from dependency pre-bundling to advanced SSR patterns. Use this when configuring new Vite projects, debugging slow dev server startup, or optimizing production bundles. Each rule lives in its own reference file with detailed examples, and the priorities are clear: critical issues like deps configuration and plugin performance come first, then bundle optimization and imports, down to medium-priority concerns like CSS tooling. The categorization is genuinely useful because it tells you what to fix first when your Vite build feels slow, rather than throwing a wall of best practices at you.
