Track: Prisma 7 + Turbopack WASM compatibility

[ColdByDefault]

Issue Summary

Currently using Webpack for production builds due to Prisma 7 WASM query compiler incompatibility with Turbopack.

Current Workaround

• Dev: Uses Turbopack (
  ext dev --turbopack) - works fine
• Build: Uses Webpack (
  ext build --webpack) - required for Prisma WASM

Root Cause

Prisma 7's WASM query compiler modules (\query_compiler_fast_bg.postgresql.mjs) aren't properly resolved by Turbopack during builds.

Error:
\
Module not found: Can't resolve '@prisma/client/runtime/query_compiler_fast_bg.postgresql.mjs'
\\

Affected Packages

• \prisma: 7.3.0
• @prisma/client: 7.3.0
• @prisma/adapter-pg: 7.3.0
• 
  ext: 16.1.x

Action Items

• Monitor Prisma releases for Turbopack support
• Monitor Next.js releases for improved WASM handling in Turbopack
• Test switching back to
  ext build --turbopack\ when either is fixed
• Consider opening upstream issue with Prisma if not already tracked

Notes

Webpack build works but is slower than Turbopack. Re-enable Turbopack for builds once compatibility is resolved.
