Poem

In a burrow deep, I found a file anew,
Docker Compose hops in, with tasks to do!
Node runs the show, dependencies in tow,
Port three thousand open, let the dev winds blow.
A rabbit’s joy, containers deploy—
Now code can grow, oh what a flow! 🐇🚀

  • @coderabbitai help me debug CodeRabbit configuration file.

Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

🧹 Nitpick comments (5)

apps/page/docker-compose.yml (5)

1-1: Prefer Compose spec 3.9 (or omit version) for modern feature-set
Compose v3 without a minor version is from 2016 and lacks newer fields (e.g., profiles, deploy). Unless you are targeting a legacy Docker Engine, bump to 3.9 or drop the version key entirely (Compose v2 CLI treats this as latest).

---

4-5: Pin the Node image to an exact patch version
node:18-alpine is a moving tag; tomorrow’s build may silently pull a different revision and break reproducibility. Pick an explicit patch (node:18.20.2-alpine) or use a locally built image via build:.

---

6-7: Mounting the whole project overwrites the container’s node_modules
Because /app is bind-mounted, any dependencies installed during image build are lost and npm install must re-run on every container start, which is slow. Typical dev pattern:

volumes:
  - .:/app
  - /app/node_modules            # anonymous volume shields installed deps

or switch to npm ci inside command: for deterministic, faster installs.

---

8-8: Replace npm install && npm run dev with npm ci for deterministic installs
npm install may mutate package-lock.json; npm ci is faster and guarantees exact lockfile versions.

-    command: sh -c "npm install && npm run dev"
+    command: sh -c "npm ci && npm run dev"

---

9-10: Expose host port via env to avoid clashes
Hard-coding 3000:3000 collides if multiple apps bind to 3000 locally. Consider:

ports:
  - "${HOST_PORT-3000}:3000"

and add HOST_PORT to .env.example.
