# How to Build Your First Full-Stack Web App

Building a full-stack application is the perfect way to understand how the web really works. You'll learn frontend, backend, databases, and how they all connect.

## What You'll Build

A simple note-taking app where users can create, read, update, and delete notes. It will have:
- A React frontend
- A Node.js/Express backend
- A MongoDB database

## Step 1: Set Up Your Backend

Create a new folder and initialize Node.js:
```bash
mkdir my-first-app && cd my-first-app
mkdir server client
cd server && npm init -y
npm install express mongoose cors dotenv
```

Create a basic Express server and connect to MongoDB. Define a Note model with title and content fields.

## Step 2: Build Your API

Create RESTful endpoints: GET /api/notes, POST /api/notes, PUT /api/notes/:id, DELETE /api/notes/:id.

## Step 3: Set Up React Frontend

```bash
cd ../client
npx create-react-app .
npm install axios react-router-dom
```

Build components for listing notes, creating notes, and editing notes.

## Step 4: Connect Frontend to Backend

Use Axios to call your API from React components. Display loading states, handle errors, and refresh the list after mutations.

## Step 5: Deploy

Deploy the backend on Render or Railway, the frontend on Vercel or Netlify.
