# Create a server using NodeJS and Typescript

Step 1: Set up a new project folder Create a new folder for your project and navigate to it in your terminal.

Step 2: Initialize the project Run the following command to initialize a new Node.js project with npm:

```bash
npm init -y
```

Step 3: Install dependencies Install the required dependencies for the project:

```bash
npm install express typescript nodemon --save-dev
```

Step 4: Create a TypeScript configuration file Create a file named `tsconfig.json` in the root of your project and add the following configuration:

```bash
{
  "compilerOptions": {
    "target": "ES2021",
    "module": "commonjs",
    "outDir": "dist",
    "strict": true,
    "esModuleInterop": true
  },
  "include": [
    "src/**/*.ts"
  ],
  "exclude": [
    "node_modules"
  ]
}
```

Step 5: Create the source files Create a folder named `src` in the root of your project and create a file named `app.ts` inside the `src` folder. This will be your main application file. Add the following code to it:

```bash
import express from 'express';

const app = express();
const port = 3000;

app.get('/', (req, res) => {
  res.send('Hello, world!');
});

app.listen(port, () => {
  console.log(`Server running at http://localhost:${port}`);
});
```

Step 6: Add a start script Open the `package.json` file and add the following `"start"` script inside the `"scripts"` section:

```bash
"scripts": {
  "start": "nodemon --exec ts-node src/app.ts"
}
```

Step 7: Start the server To start the server, run the following command in your terminal:

```bash
npm start
```

Now, whenever you make changes to your TypeScript files, Nodemon will automatically restart the server for you, so you don't have to do it manually.

That's it! You now have a Node.js and TypeScript setup with Nodemon to avoid manually restarting the server every time you make changes. Feel free to customize and expand on this setup as needed for your project.
