oRPC + Cloudflare + Tanstack Start build error "cloudflare:workers" #685
Description
Issue
When I create a project combining oPRC and Tanstack Start and run bun run build, I get an error "Module not found, treating it as an external dependency" from "cloudflare:workers". It seems that importing the auth package from the web is the cause.
Configuration
bun create better-t-stack@latest my-app --frontend tanstack-start native-nativewind --backend hono --runtime workers --api orpc --auth better-auth --payments none --database sqlite --orm drizzle --db-setup turso --package-manager bun --git --web-deploy none --server-deploy alchemy --install --addons oxlint turborepo --examples todo
