Cannot access Cloudflare bindings (env) – always undefined with vite-plugin-cloudflare & nitro-cloudflare-dev

[akawahuynh]

I'm working on integrating Cloudflare D1 with a frontend app using TanStack Start, and trying to run API routes (Cloudflare Pages Functions style) locally with vite-plugin-cloudflare and nitro-cloudflare-dev.

However, env (which should include D1 bindings) is always undefined, both locally and in preview builds.

Guidance on whether this setup is supported

If vite-plugin-cloudflare supports Pages bindings like env.DB

Or if there's a better way to emulate full env bindings locally

Thanks a ton in advance! Appreciate all the work you’re doing in both projects
