Hitting Cloudflare Workers' 3MB size limit while deploying Next.js
A builder is trying to deploy a stack of Next.js, Better Auth, Stripe, and OpenNext (used to build a starter called LaunchSaaS) to , but the Worker bundle exceeds the platform's 3MB size limit. Even after enabling Miniflare, minifying the code, and applying basic s, the bundle stays too large.

The request is for real s, , and fixes from anyone who has successfully shipped a similar stack on Workers.
