## Creating Your First Node.js Project
### Initializing the Project
1. Open the terminal (press Ctrl+` in VS Code)
2. Create project folder and enter: mkdir my-node-app
cd my-node-app

### Creating the Main File
1. Create `app.js` file in VS Code
2. Enter the following code: ## Example
const http = require('http');
const server = http.createServer((req, res)=>{
res.statusCode=200;
res.setHeader('Content-Type','text/plain');
res.end(' TUTORIAL Node Test ~ Hello, Node.js!n');
});
const port =3000;
server.listen(port,()=>{
console.log(`Server running atοΌhttp://localhost:${port}/`);
});
### Running the Project
1. Execute in terminal: node app.js
!(#)
2. Open browser and visit `http://localhost:3000`
