Create a Node.js application that fetches weather information from the OpenWeatherMap API for a given city and displays the current temperature, humidity, and wind speed.

To create a Node.js application that fetches weather information from the OpenWeatherMap API, follow these steps:

1. Install Node.js on your computer if you haven't already.

2. Create a new directory for your project and navigate to it in your terminal or command prompt.

3. Run `npm init` to create a package.json file for your project. Follow the prompts to set up your project's details.

4. Install the required packages: Axios (for making HTTP requests) and dotenv (for managing environment variables). To do this, run the following command:

```
npm install axios dotenv
```

5. Create a `.env` file in your project directory and add your OpenWeatherMap API key like this:

```
OPENWEATHERMAP_API_KEY=your_api_key_here
```

Replace "your_api_key_here" with your actual API key. You can obtain an API key by signing up for a free account at https://openweathermap.org/api.

6. Create a new file called `index.js` in your project directory and add the following code:

```javascript
require('dotenv').config();
const axios = require('axios');

const apiKey = process.env.OPENWEATHERMAP_API_KEY;
const city = 'New York'; // Replace with the desired city

const getWeatherData = async (city) => {
  try {
    const response = await axios.get(
      `https://api.openweathermap.org/data/2.5/weather?q=${city}&appid=${apiKey}&units=metric`
    );

    const { temp, humidity } = response.data.main;
    const { speed } = response.data.wind;

    console.log(`City: ${city}`);
    console.log(`Temperature: ${temp}°C`);
    console.log(`Humidity: ${humidity}%`);
    console.log(`Wind Speed: ${speed} m/s`);
  } catch (error) {
    console.error(`Error fetching weather data: ${error.message}`);
  }
};

getWeatherData(city);
```

Replace `'New York'` with the desired city for which you want to fetch the weather information.

7. Save your changes and run the application by executing `node index.js` in your terminal or command prompt. The current temperature, humidity, and wind speed for the specified city will be displayed.

Note that this is a simple example without user input or error handling for invalid cities. You can expand upon this code to create a more robust application if needed.
