# Dockerfile for web-antrean Nuxt.js Application
# Multi-stage build for optimized image size and native modules support

# Stage 1: Build Stage
FROM node:20-alpine AS builder

# Install build dependencies for compiling native addons (like better-sqlite3)
RUN apk add --no-cache python3 make g++ gcc libc-dev

# Set working directory
WORKDIR /app

# Copy package files
COPY package*.json ./

# Install dependencies (including devDependencies for build)
RUN npm ci

# Copy application files

# Build the application for production
RUN npm run build

# Stage 2: Production Stage
FROM node:20-alpine AS runner

# Install runtime dependencies (like libc6-compat for compatibility with precompiled binaries)
RUN apk add --no-cache libc6-compat

# Set working directory
WORKDIR /app

# Copy package files
COPY package*.json ./

# Copy built output and compiled node_modules from builder stage
# This avoids needing to install build tools (g++, make, python) in this slim production stage
