Vite deployment guide: zero-ops edge publishing with Cloudflare Pages
Git-driven Vite deployment in practice: commit to build, atomic publish to every edge node.
Quick answer
What breaks when Vite manualChunks is misconfigured?
Misconfiguration can pull CSS into JS or create circular dependencies, growing the first-paint bundle. Start with a coarse vendor split, then refine.

In-depth analysis
Vite's native-ESM dev server and Rollup-based production bundling set the baseline for modern frontend build performance and developer experience. At deploy time hand the built artifact to the edge platform and lean on static fallback plus security headers to hold the line on stability.
// vite.config.ts — production build, deep optimization
import { defineConfig } from 'vite';
export default defineConfig({
build: {
target: 'es2022',
cssCodeSplit: true,
rollupOptions: {
output: { manualChunks: { vendor: ['vue', 'react'] } },
},
},

FAQ & pitfalls
How do Vite build artifacts get long-cached at the edge?
Hash-filename assets get immutable long cache; entry HTML gets must-revalidate. Changing the filename changes the URL, which naturally sidesteps cache stampedes.

Questions that keep coming back in reader feedback, already answered.
- 01
What goes wrong when Vite manualChunks is misconfigured?
A wrong split pushes styles into the JS bundle or creates circular dependencies, and first-paint size goes up instead of down. Start with a coarse vendor split, then refine it.

Why is my Astro component's interactivity not working?
Components ship as zero-JS HTML by default, so an interactive one needs a client:* directive (client:load, client:visible, …). Without it the script is never bundled into the page.

Why is my custom Tailwind v4 brand colour not applied?
Colours must be declared in @theme (for example --color-brand). A missing @tailwindcss/vite plugin, or a leftover v3 config, makes bg-brand silently render nothing.
