Dockerfile

# syntax=docker/dockerfile:1
#
# Production image for the OSForms web app (apps/web) in the pnpm + Turborepo
# monorepo. Builds @osforms/react + @osforms/types first (via Turbo's ^build),
# then the Next.js app with `output: "standalone"`, and runs the traced server
# on a minimal runtime. See SELF_HOSTING.md for the full self-host guide.

# Raise V8's heap ceiling above its ~2GB default so `next build` (Turbopack +
# React Compiler over a large app) doesn't OOM. 4GB clears the build while
# leaving VM headroom for Turbopack's native allocations. Needs a >=6GB Docker VM.

# node_modules copy, which is what breaks pnpm symlinks).
