**Short answer.** Build in one stage with dev dependencies, then copy only the built output and production dependencies into a slim final image.

## Example

```dockerfile
FROM node:24-alpine AS build
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build && npm prune --omit=dev

FROM node:24-alpine
WORKDIR /app
ENV NODE_ENV=production
COPY --from=build /app/node_modules ./node_modules
COPY --from=build /app/dist ./dist
COPY package.json .
USER node
CMD ["node", "dist/index.js"]
```

## Details

- Copy `package*.json` before the source so the dependency layer caches until dependencies change.
- `npm ci` needs a lockfile and is deterministic; `npm install` is not.
- Run as a non-root user; the official images provide `node`.
- Add a `.dockerignore` with `node_modules`, `.git`, and build output.

## Pitfalls

- Native modules built on Alpine (musl) differ from Debian (glibc); use the same base in both stages.
- Missing `HEALTHCHECK` or signal handling; `node` as PID 1 does not forward signals without `--init` or `tini`.
