viteVite Dev Speed Comes From Native ESM, Not Faster Bundling
Vite avoids slow cold starts by serving source files as native ES modules in dev and pre-bundling CommonJS dependencies on demand with esbuild. This keeps startup fast and HMR stable when configured with optimizeDeps.
Vite dependency pre-bundling: why dev goes stale and how optimizeDeps fixes it
Vite pre-bundles node_modules with esbuild in dev, so a stale optimized bundle is usually a cache and discovery problem — not a broken install.
vitejsWhy Your Vite Dev Server Starts Fast: Dependency Pre-Bundling with optimizeDeps
Vite pre-bundles your dependencies with esbuild at dev-server startup, turning hundreds of module requests into one per package. Here's how it works, how to verify it, and when to tune optimizeDeps.
Vite Dependency Pre-Bundling: How esbuild Speeds Up Your Dev Server
Vite pre-bundles CommonJS dependencies with esbuild at startup to serve native ES modules instantly. Learn how the cache works, how to tune optimizeDeps, and the trade-offs for dev server speed.
Why Vite Pre-Bundles Dependencies with esbuild and How to Manage the Trade-offs
Vite speeds up dev server startup by pre‑bundling node_modules with esbuild, caching the result, and letting you control the process via optimizeDeps. Learn how it works, its limits, and practical checks.
Vite's Dependency Pre-Bundling: How the Cache Works and When to Override It
Vite's dev server feels instant because esbuild pre-bundles node_modules into single-file ESM before the browser ever asks. Here's how the cache invalidates — and the monorepo case it misses.

javascriptWhy Vite Feels Instant: Native ESM Serving and Dependency Pre-Bundling Explained
Vite's speed comes from two decisions: serving source as native ES modules and pre-bundling dependencies once. Here's how both work, how to verify them, and where they break down.
