SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill fixes slow Vite build performance and bloated production bundles that hurt startup time, navigation speed, and Core Web Vitals.

Core Features & Use Cases

Avoid barrel import bottlenecks that force unused modules to load, especially in large React UI/icon libraries.
Split bundles deliberately using manual chunking and route-level dynamic imports to improve caching and reduce initial payload.
Optimize runtime work by deferring third-party scripts, preloading critical route assets, and tuning dependency pre-bundling.

Quick Start

Ask the AI to optimize your Vite production build by removing barrel imports, adding manualChunks, and introducing route-based dynamic imports for your React pages.

FAQPage Schema

How do I fix slow Vite build performance and oversized vendor chunks?▼

To fix slow Vite build performance and oversized vendor chunks, apply manual chunk splitting, remove barrel imports, and use route-level dynamic imports. This reduces initial payload and improves app loading speed.

What is the best way to split bundles in a Vite and React application?▼

The best way to split bundles in a Vite and React application is combining manual chunking with route-level dynamic imports. This deliberately divides code to improve caching and reduce the initial payload.

Why does my Vite app have excessive dev startup time and poor route loading?▼

Excessive dev startup time and poor route loading in Vite often stem from barrel import bottlenecks and unoptimized dependency pre-bundling. Deferring third-party scripts and preloading critical assets resolves these performance regressions.

How do barrel imports affect bundle optimization in Vite?▼

Barrel imports negatively affect bundle optimization in Vite by forcing unused modules to load, especially in large React UI libraries. Removing them prevents unnecessary payload bloat and improves startup time.

Can I use dynamic imports to improve Core Web Vitals in Vite?▼

Yes, you can use dynamic imports to improve Core Web Vitals in Vite. By splitting route-level bundles and deferring third-party initialization, you reduce initial JavaScript execution and improve navigation speed.

Does this bundle optimization approach work for Vite + React applications specifically?▼

Yes, this bundle optimization approach is designed for Vite + React applications. It applies Rollup bundle splitting, dependency pre-bundling, and dynamic imports to prevent performance regressions in React components.
