FAQPage Schema
How do I migrate a project from Vite 6 to Vite 8 with Rolldown?

To migrate from Vite 6 to Vite 8, update your vite.config.ts for Rolldown bundler compatibility, account for Oxc transformer changes, and verify multi-environment support to keep TypeScript and ESM workflows intact.

How does the Vite plugin API work for SSR middleware and library builds?

The Vite plugin API uses specific hooks, virtual modules, and ordering rules to process assets and HMR. It integrates with the JavaScript API to manage build tasks for SSR middleware and library outputs.

What is the best way to configure vite.config.ts for a multi-tenant React app?

Configuring vite.config.ts for multi-tenant React apps involves using defineConfig, conditional setups, loadEnv, and alias management. This ensures proper environment variable loading and path resolution for your specific project structure.

Does Vite 8 with Rolldown support conditional build setups and import.meta.glob?

Yes, Vite 8 with Rolldown supports conditional build setups and import.meta.glob. It provides environment APIs and asset query handling to manage complex build configurations and dynamic module loading effectively.

Why do I need to adjust plugin ordering when using the Rolldown bundler in Vite 8?

Adjusting plugin ordering is necessary because the Rolldown bundler changes how hooks and virtual modules are processed. Correct ordering ensures HMR, asset queries, and SSR middleware function without environment conflicts.
