MERN Notes App

A minimal MERN note-taking app with CRUD and a very simple UI (no build step, React via CDN).

Prerequisites

• Node.js 18+
• MongoDB running locally or a MongoDB URI

Setup

1. Install dependencies:

   npm install

2. Create .env from example and set your Mongo URI if needed:

   copy .env.example .env   # Windows
   # or
   cp .env.example .env     # macOS/Linux

3. Start server:

   npm run start
   # or during development with auto-reload
   npm run dev

4. Open http://localhost:3000 in your browser.

API

• GET /api/notes – list notes
• POST /api/notes – create note { title, content }
• GET /api/notes/:id – get one
• PUT /api/notes/:id – update { title, content }
• DELETE /api/notes/:id – delete

Notes

• The frontend is served from public/ and uses React 18 via CDN and Babel for JSX.
• Data model is title, content, and timestamps.
