Describe the Bug

Cloudflare's Vite plugin works without error, but causes the following warnings:

You or a plugin you are using have set `optimizeDeps.esbuildOptions` but this option is now deprecated. Vite now uses Rolldown to optimize the dependencies. Please use `optimizeDeps.rolldownOptions` instead.

Please provide any relevant error logs

No response

Thanks for the issue. We'll be improving compatibility with Vite 8 during the beta period.

FYI one thing that doesn't work between the Cloudflare Vite plugin and Vite 8 is that the Cloudflare plugin sets "es2024" as the build target and Vite errors on build with

error during build:
Build failed with 1 error:

[plugin vite:css-post]
Error: [lightningcss minify] Unsupported target "es2024"

I've created an issue and a PR for the Vite CSS plugin to add "es2024" as a build target.

This just landed in 8.0.0-beta.4.

Hi @bndkt. Thanks so much for opening the PR to Vite to fix this!
