In this tutorial, we will learn how to retrieve our IP address using Node.js. Knowing your IP address can be very useful in various scenarios, such as setting up a server, troubleshooting network issues, or implementing security measures. Node.js is a popular runtime environment that allows you to run JavaScript on the server side.
To get started, make sure you have Node.js installed on your system. You can download the latest version from the official Node.js website (https://nodejs.org/).
Now, let’s create a new Node.js project. Open a terminal or command prompt and run the following command:
mkdir get-ip-address
cd get-ip-address
npm init -y
This will create a new directory called get-ip-address
and initialize a new Node.js project. Next, we need to install a package called request
that will help us make HTTP requests. Run the following command in the terminal:
npm install request
Once the package is installed, create a new file called getIpAddress.js
in the get-ip-address
directory. Open the file in a text editor and add the following code:
const request = require('request');
request('https://api.ipify.org', function (error, response, body) {
if (!error && response.statusCode === 200) {
console.log('Your IP address is: ', body);
} else {
console.log('Failed to fetch IP address');
}
});
In this code, we are using the request
package to make an HTTP GET request to https://api.ipify.org
, which is a free service that returns your IP address. When the request is successful, we log the IP address to the console. If there is an error, we log a failure message.
Save the file and return to the terminal. Run the following command to execute the script:
node getIpAddress.js
You should see your IP address printed on the console. Congratulations, you have successfully retrieved your IP address using Node.js!
This is just a simple example of how to get your IP address using Node.js. You can further enhance this script by adding error handling, logging the IP address to a file, or integrating it into a larger application.
