Vite 6: The Environment API Revolution
Vite 6 brings major improvements for server-side rendering and advanced build scenarios.

Environment API

The new Environment API allows you to define different module resolution strategies for client and server:

javascript

export default defineConfig({


  environments: {
    client: {
      // Client-specific config
    },
    ssr: {
      // SSR-specific config
    },
  },
});

More reliable HMR

Reduced memory usage

The build tool ecosystem keeps evolving.
