# client/Dockerfile
# 1. Use an official Node.js image as the base
FROM node:19-alpine AS builder

# 2. Create and set the working directory
WORKDIR /app

# 3. Copy package manifests and install dependencies
COPY package*.json ./
RUN npm install

# 4. Copy your Next.js source code
COPY . .

# 5. Build the Next.js app
RUN npm run build

# 6. Use a lightweight webserver for the final image (or continue with Node SSR)
#   Option A: If you use Next.js "standalone" + "output: 'standalone'" in next.config.js:
#       https://nextjs.org/docs/advanced-features/output-file-tracing
#   Option B: Run Next.js in Node as usual.
#   We'll do SSR with Node below.
