Core rules

• Prefer minimal configuration; extend only as needed.
• Keep index.html as a first-class entry point when using Vite defaults.
• Treat dev server settings and build settings separately.
• Document mode-dependent behavior for env variables and define.
• Use future config to opt-in to deprecation warnings before migration.

Recipes

• Scaffold a project with npm create vite@latest.
• Configure aliases, server options, and build outputs in vite.config.*.
• Load .env values into config with loadEnv when config needs them.
• Add plugins with plugins: [] and define apply or enforce when needed.
• Use HMR APIs for fine-grained updates when plugin or framework needs it.
• Use optimizeDeps.include/exclude when deps aren't discovered on startup.
• Use build.rollupOptions.input for multi-page apps.
• Enable deprecation warnings: future: {removeSsrLoadModule: 'warn'}.
• Use hotUpdate hook instead of handleHotUpdate for environment-aware HMR.
• Use this.environment instead of options.ssr in plugin hooks.

Release Highlights (8.0.0)

• Default browser target is raised again under baseline-widely-available.
• CommonJS default-import interop becomes more consistent and may expose packages that relied on older ambiguous behavior.
• Vite stops resolving browser vs module via format sniffing and follows configured resolve.mainFields more strictly.
• JS API build() now throws BundleError with nested .errors when multiple Rolldown-level errors are present.
• Rolldown transition becomes more explicit: build.rollupOptions / worker.rollupOptions are deprecated in favor of *.rolldownOptions.

Prohibitions

• Do not copy large verbatim chunks from vendor docs.
• Do not assume framework-specific behavior without verifying.
