Workers - Improved React Server Components support in the Cloudflare Vite plugin

The Cloudflare Vite plugin now integrates seamlessly @vitejs/plugin-rsc ↗︎, the official Vite plugin for React Server Components ↗︎.

A childEnvironments option has been added to the plugin config to enable using multiple environments within a single Worker. The parent environment can then import modules from a child environment in order to access a separate module graph. For a typical RSC use case, the plugin might be configured as in the following example:

vite.config.tsts

export default defineConfig({
	plugins: [
		cloudflare({
			viteEnvironment: {
				name: "rsc",
				childEnvironments: ["ssr"],
			},
		}),
	],
});

@vitejs/plugin-rsc provides the lower level functionality that frameworks, such as React Router ↗︎, build upon. The GitHub repository includes a basic Cloudflare example ↗︎.
