Create a currency converter using Javascript and API

Hello friends, today in this blog, we will learn how to create a currency converter using Javascript and API. Our previous blog showed how to create a random color generator with a 3D Effect. You can check my other javascript projects after reading this blog.

In today's globalized world, it's not uncommon to need to convert currency regularly. Whether you're traveling abroad, making international transactions, or simply want to keep track of the value of your investments in different currencies, having access to an accurate and easy-to-use currency converter is essential. 

In this blog post, we'll show you how to create a currency converter using JavaScript and an API. JavaScript is a powerful and widely used programming language that can be used to create dynamic and interactive web applications, while an API (Application Programming Interface) allows us to connect to external services and retrieve data in a structured way. By combining these two tools, we can create a simple yet effective currency converter that can be used by anyone with an internet connection.

Whether you're a beginner or an experienced developer, this tutorial is designed to be accessible and easy to follow. We'll walk you through each step of the process, from setting up the project to fetching data from the API and displaying the results. By the end of this tutorial, you'll have a fully functional currency converter that you can use and customize to suit your needs. So, let's get started!

In this project, there is a currency converter as you can see in the image above. You just need to enter the amount and select the currency you want to convert. For example, let's assume I want to convert Indian Rupees. So I will click on the county Flag and a pop-up modal will be opened and I will be able to select a currency, there is a search option, and I can search currencies. I no result is found then this message will be shown:-
After selecting the currency, the results of all currencies will be shown and you can search which currency result you want.

Let's Set up the Project

  1. Create a new folder for your project and name it something descriptive.
  2. Inside the project folder, create a new file called index.html. This will be your main HTML file.
  3. Open index.html in a code editor such as Visual Studio Code.
  4. Inside the head section of index.html, create a new link element that links to your CSS file. The link element should look like this: "<link rel="stylesheet" href="styles.css">" Make sure to replace styles.css with the name of your CSS file.
  5. Save the changes to index.html.
  6. In the same project folder, create a new file called styles.css. This will be your main CSS file.
  7. Open styles.css in a code editor.
  8. Write your CSS rules inside styles.css.
  9. Save the changes to styles.css.
  10. In the head section of index.html, create a new script element that links to your JavaScript file. The script element should look like this: "<script src="script.js"></script>" Make sure to replace script.js with the name of your JavaScript file.
  11. Save the changes to index.html.
  12. In the same project folder, create a new file called script.js. This will be your main JavaScript file.
  13. Open script.js in a code editor.
  14. Write your JavaScript code inside script.js.
  15. Save the changes to script.js.
Now you have successfully created a basic HTML, CSS, and JavaScript file and linked them together. Any changes you make to your CSS or JavaScript files will be reflected in your index.html file when you refresh the page.

Here's the good news: you don't have to write all the code of this project from scratch! I have created a GitHub repository that contains all the HTML, CSS, and JavaScript code needed to build the app. You can check it out and use it as a starting point for your own project.

HTML CODE

Just paste this code into HTML File which you have created.
