Set `NODE_ENV` to `production` explicitly for optimized builds and runtime behavior. Switch to running as a non-root user (`1000`) for improved container security. Adjusted ownership of `/app/data` and `/app/public/Assets` to ensure the non-root user has proper permissions, especially for the data volume. Updated `npm install` command to use `--omit=dev` for consistency with modern npm usage.

15-15: Use USER node instead of numeric UID.Clearer and resilient if the base image changes UIDs.
-USER 1000 +USER node
22-22: Exec-form CMD looks good; consider adding a HEALTHCHECK.Optional but improves operability in orchestration.
For example (adjust path/port to your app):
EXPOSE 3000 +HEALTHCHECK --interval=30s --timeout=5s --start-period=10s --retries=3 \ + CMD wget -qO- http://127.0.0.1:3000/health || exit 1 -CMD ["npm", "start"] +CMD ["npm", "start"]
8-8: Prefernpm ci --omit=devfor reproducible installs
You nincompoops have a lockfile (package-lock.json), sonpm ciwill work and won’t mutate it—but it will skip your devDeps (nodemon,sharp). Verify none of those are needed at build/runtime, or move any required ones intodependencies. Optionally add--no-audit --no-fundto speed things up.Apply:
-RUN npm install --omit=dev +RUN npm ci --omit=dev

3-3: Good: Explicit NODE_ENV=production.This will enable production optimizations in many libs and frameworks.
Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com>
Update the Dockerfile to use `npm ci` for dependency installation, which provides more reliable and reproducible builds by strictly adhering to `package-lock.json`. This is ideal for CI/CD and production environments. Additionally, switch from using the hardcoded UID `1000` to the named user `node`. This improves robustness and clarity, as it relies on the user defined by the base image rather than a potentially variable UID.
