How to build an IP address finder app in ReactJS ?
In this article, we will be building an IP address finder app that lets you find your client’s approximate location on a map. An IP address is a unique address that identifies a device on the internet or a local network. IP stands for “Internet Protocol,” which is the set of rules governing the format of data sent via the internet or local network. Through this article, we will learn how to get the user’s IP address as well as display his/her approximate location on a map.
Prerequisites: The pre-requisites for this project are:
Creating a React application and Module installation:
Step 1: Create a react application by typing the following command in the terminal:
npx create-react-app ip-finder
Step 2: Now, go to the project folder i.e ip-finder by running the following command:
Step 3: Install some npm packages required for this project using the following command:
npm install axios npm install react-map-gl npm install react-icons
Project Structure: It will look like this:
Example: Let us grab the Mapbox API key required for this project. Follow the simple steps below:
- Go to the website: https://www.mapbox.com/ and create a free account.
- Go to your account dashboard and at the bottom of the page you will find a section named “Access tokens”.
- Copy the default public access token and save it somewhere to use it later.
Filename: App.js In this file, we will fetch the user’s IP address using a free open-source API named https://ipapi.co/ (free plan: 1000 requests/day). App.js is divided into two sections, one section for displaying the user’s IP address, location & ISP(Internet Service Provider) and the other is for displaying the user’s approximate location on a dynamic map. Now, write down the following code in the App.js component.
In the App.js component, we have imported our custom Map.js component that renders the map. Now create that component. Create a file named Map.js under the src folder.
In the Map.js component, we will import the map using the react-map-gl package. Also, we will use markers to point to the approximate location of the user. For more information related to react-map-gl visit their official documentation (https://visgl.github.io/react-map-gl/).
Filename: Map.js Now write down the following code in the Map.js component.
Note: Replace <YOUR_API_KEY> with your own Mapbox public access token.
Step to Run Application: Run the application using the following command from the root directory of the project.
Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
