##### DEPENDENCIES

FROM --platform=linux/amd64 oven/bun:1-alpine AS deps
RUN apk add --no-cache libc6-compat openssl
WORKDIR /app

ARG DATABASE_URL

ARG NEXT_PUBLIC_CLIENTVAR
# NEXT_PUBLIC_* vars are inlined into the client bundle at build time, so they
# must be present during `bun run build`. Railway exposes service variables as
# build args automatically; promote it to an ENV so Next.js picks it up.

# Placeholder so import-time clients (e.g. Resend) don't throw during the build.
# Build-only; the runner stage is a separate image and supplies real values at runtime.
