Country Information is a web application to get the country’s information using ReactJS. This project basically implements functional components and manages states. The user can insert the country name in the search input field, and after clicking the search button, this application makes an API call to retrieve the specific country information. If the country name is not valid, then it will show an error message. This application is implemented using ReactJS and has a simple and responsive UI.

Prerequisites and Technologies:
Approach/Functionalities:
Utilizes ReactJS functional components and state management to create an interactive web-based Country Information Finder. User can insert the country name in input element and after clicking on search button application makes an api call to external restcountries.com API to retrieve the information for specific country name. If API call is rejected then it shows an error message otherwise this API request provides various information about the specific country like country’s name, flag image, capital, population, borders, area, calling code etc.
Steps to create the application:
Step 1: Set up React project using the command
npx create-react-app <<name of project>>
Step 2: Navigate to the project folder using
cd <<Name_of_project>>
Step 3: Create a folder “components” and add three new files in it and name them as CountryInfo.js, CountryInformation.js and CountryInformation.css.

Example: Write the following code in respective files
- App.js: This file imports the CountryInformation components and exports it.
- CountryInformation.js: This file contains a logic to allow users to search for country information by entering a country name and passes the retrieve data to child component CountryInfo.js.
- CountryInfo.js: It displays data, including flags, capital, population, and more, providing a user-friendly interface for exploring country details.
- CountryInformation.css: This file contains the design of the CountryInformation elements.
