Here, we will learn a step-by-step process to add a country flag icon using Angular in an easy way.

Introduction

 
In this article, we will learn how to add a country flag icon on a website using Angular and Bootstrap 4.
 
Prerequisites
  • Node

Description
 
Here, I will show you the steps to add country flag icons on our website. Also, we can add flag icons for corresponding countries with languages for translating the website to other languages.
 
Note
Before going through this session, please visit my previous article related to Angular 7 application.
Step 1
 
In this step, we need to install the flag icon packages using NPM by using the below command.
 
npm install flag-icon-css 
 
Step 2
 
After successful installation, the file structure in the node_modules folder should look like the below image. Here, we can get a collection of all country flags in SVG with the CSS for easier integration.

Code Desc

In this section, for using the flags inline with text, add the classes .flag-icon and .flag-icon-xx (where xx is the ISO 3166-1-alpha-2 code of a country) to an empty <span>. If you want to have a squared version flag, then add the class flag-icon-squared. For example, I have added an Indian flag. The ISO 3166-1-alpha-2 code of India is "in" and this code should be case sensitive.
 
Here is the list of ISO 3166 country codes and flags for future reference.
