# Copy package files AND .npmrc (critical for better-auth + Prisma 7 compatibility)
# .npmrc contains legacy-peer-deps=true to handle better-auth peer dependency warnings
COPY package.json package-lock.json* .npmrc ./

# Copy Prisma schema BEFORE npm ci
# This is required because the postinstall script runs "prisma generate"
COPY prisma ./prisma

# Install dependencies
# Uses npm ci for reproducible builds based on package-lock.json
# The postinstall script will run "prisma generate" automatically
RUN npm ci

# Copy application source
# Note: In development, source code is mounted as a volume in docker-compose.yml
# This COPY ensures the image can run standalone, but hot-reload comes from volume mount
COPY . .

# Expose Next.js development server port
EXPOSE 3000

# Set environment variables
# NODE_ENV=development enables Next.js dev features (Fast Refresh, better errors)
ENV NODE_ENV=development
ENV PORT=3000
# HOSTNAME="0.0.0.0" allows connections from outside the container
ENV HOSTNAME="0.0.0.0"

# Hot reload works through volume mounts configured in docker-compose.yml
