What is this?
Frontend Vite React App prepares your MERN toolchain and project shape.
Why should you care?
Without clean setup, React and Express fight ports, CORS, and env.
See it live — copy this example
Run examples in your MernVerse client/ (Vite React) or server/ (Express) folders. Keep secrets in .env.
# Frontend Vite React App
# client (Vite) :5173 server (Express) :5000
echo "MernVerse folders + env ready"What happened?
- Separate client/server, pin Node LTS, and keep secrets in .env.
- Follow the steps below — typing the code yourself is the fastest way to learn.
Practice next
- Reproduce the snippet in your your MERN app folders.
- Change one line and re-run client or server.
- Confirm the other side still works (CORS/API).
- Extract a shared helper.
- Add a quick happy-path test later.
