Support Cloudflare Vinext (Next.js on Vite/Workers) #19514

Cloudflare released vinext, a ground-up reimplementation of the Next.js API as a Vite plugin targeting Cloudflare Workers. It replaces webpack with Vite and runs everything in the workerd runtime.

We're investigating what it would take to support it.

Initial assessment

• vinext supports instrumentation.ts with the same register() + onRequestError() hooks our Next.js SDK uses
• @sentry/cloudflare already has first-class Workers support
• @sentry/vite-plugin should handle source map upload
• Our webpack/turbopack-based auto-instrumentation (wrapping loaders, route manifest, value injection) won't transfer — needs Vite equivalents
• Client-side routing instrumentation likely needs adaptation
• Server-side context propagation between vinext's separate RSC/SSR environments needs investigation

Status

Vinext is still experimental. We'll start with low-cost validation to see how far existing SDKs get us.
