# Running `npm ci` removes the existing node_modules directory and passing in --only=production ensures that only the production dependencies are installed. This ensures that the node_modules directory is as optimized as possible
RUN npm ci --only=production && npm cache clean --force

USER node

FROM node:20-alpine
