Learn how Vite’s esbuild‑powered pre‑bundling trims dev‑server startup time, how to tweak it with optimizeDeps, and when it might backfire.
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 pre-bundles node_modules with esbuild in dev, so a stale optimized bundle is usually a cache and discovery problem — not a broken install.
Learn how Waku’s dev server watches files, rebuilds only changed modules, and serves assets with cache‑busting headers so you can see updates in the browser without manual refreshes.
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 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.
Get a Vite dev server running, prove HMR actually works via the WebSocket check, and fix the common Docker/reverse-proxy cases where hot reload silently fails.
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.
