Wxt Browser Extensions

A comprehensive performance guide for WXT browser extension development with 49 prioritized rules across eight categories, from critical service worker lifecycle patterns to TypeScript conventions. Use this when building or refactoring WXT extensions to catch common pitfalls like service worker state management, content script injection timing, and messaging architecture mistakes. The categorization by impact level (critical to low-medium) is genuinely useful for knowing what to focus on first. Covers the full stack of extension development including manifest configuration, storage patterns, and bundle optimization. Updated for WXT v0.20+, so it reflects current best practices rather than outdated patterns that still float around in extension development tutorials.
