# Debian (glibc), not alpine (musl): the @meshsdk/core-csl / whisky-evaluator
# WebAssembly modules don't resolve under musl during `next build`.
#
# Two stages:
#   - `base`  : deps + source. Used by the ci-runner service, which only runs
#               tsx scripts and must NOT run `next build`.
#   - `app`   : base + a production `next build`. Used by the app service.

# (`next build` + `next start`) and the ci-runner (tsx scripts that import the
# Mesh SDK) need it, so set it on the shared base stage.

# Pre-bundle the CI CLI scripts with esbuild and run them with plain node.
# tsx's esbuild loader can't defer whisky-evaluator's .wasm imports to node's
# native --experimental-wasm-modules handling, so `tsx bootstrap.ts` fails to
# load @meshsdk/core-csl. Bundling (resolving @/ aliases, externalizing
# node_modules) lets `node --experimental-wasm-modules` load the WASM natively.

# Build the production app so the smoke runs `next start` (not `next dev`) and
# exercises the same output Vercel deploys. `next dev` mis-resolves the
# @meshsdk/core-csl / whisky-evaluator WASM path at runtime, 500-ing tx routes.
# Connection URLs are only needed at runtime (compose overrides these); the
# dummy DATABASE_URL keeps build-time module evaluation of the pg adapter happy.
# (NODE_OPTIONS=--experimental-wasm-modules is inherited from the base stage.)
