Why should you care?

Local demos are not deployable systems.

See it live — copy this example

Run examples in your MernVerse client/ (Vite React) or server/ (Express) folders. Keep secrets in .env.

# Deploy Frontend Separately
npm run build --prefix client
NODE_ENV=production node server/index.js

What happened?

• Build the SPA, configure env per environment, and add health checks.
• Follow the steps below — typing the code yourself is the fastest way to learn.

Practice next

1. Reproduce the snippet in your your MERN app folders.
2. Change one line and re-run client or server.
3. Confirm the other side still works (CORS/API).
4. Extract a shared helper.
5. Add a quick happy-path test later.

Remember

You can explain Deploy Frontend Separately simply. You ran a small MERN demo. You know one pitfall.

Deploy Frontend Separately in MernVerse

Your team applies deploy frontend separately on a SaaS feature.

Outcome: A concrete next coding step exists.
