# Install all dependencies, including devDependencies needed for building
RUN npm ci
# Copy the rest of the application source code
COPY . .
# Compile TypeScript to JavaScript

# Copy package files again
COPY package*.json ./
# Install *only* production dependencies. This makes the image smaller.
RUN npm ci --only=production

# Create and switch to a non-root user for security.
# Running containers as root is a major security risk.
