# Nakama with Custom Chess Modules
# =============================================================================
# Two-stage build:
#   1. Build TypeScript modules with Node.js
#   2. Copy compiled JS to Nakama runtime
# =============================================================================

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

WORKDIR /app

# Copy module files
COPY modules/package*.json ./
RUN npm ci

# Copy source and build
COPY modules/tsconfig.json ./
COPY modules/src ./src

# Build with esbuild (output to build/index.js)
RUN npm run build

# Verify build output exists
RUN ls -la build/ && test -f build/index.js

# Stage 2: Nakama runtime with modules
FROM registry.heroiclabs.com/heroiclabs/nakama:3.21.1

# Copy compiled JavaScript modules
# Nakama expects modules at /nakama/data/modules/
COPY --from=builder /app/build/index.js /nakama/data/modules/main.js

# Copy config file (optional - can also be passed via CLI)
COPY config.yml /nakama/data/config.yml
