TL;DR

Learn how to build a currency converter app using React, Tailwind CSS, and custom hooks to fetch data from an API and handle user input.

Key Insights

• 🏛️ Building smaller projects that focus on specific concepts, like component reusability, is an effective approach for beginners to learn React.
• 💨 Customized hooks in React provide a way to encapsulate complex logic and make it reusable across multiple components.
• 👻 Tailwind CSS is a helpful framework for quickly styling UI components, allowing developers to focus on functionality rather than design.
• ☠️ APIs provide a convenient way to access and leverage external data within an application, such as currency conversion rates.

Questions & Answers

Q: How does the customized hook in this project work?

The customized hook, called "useCurrencyInfo," fetches currency conversion data from an API based on the selected currency. It returns the data, which includes all conversion rates for various currencies, allowing the app to display the most up-to-date results.

Q: How is component reusability implemented in this project?

Component reusability is a core principle of React, and it is demonstrated in this project through the creation of the "InputBox" component. This component accepts props like label, amount, currency options, and handlers for amount and currency change, making it easily reusable in different parts of the app.

Q: How does the app handle user input for currency conversion?

The app uses input fields and dropdown menus to capture user input. By tracking changes in the input fields and dropdown menus, the app updates the corresponding states (amount, from currency, to currency), triggers the conversion function, and displays the converted amount in real-time.

Q: Can the app handle conversions for currencies other than USD and INR?

Yes, the app is designed to fetch conversion rates for multiple currencies from the API. By providing the appropriate URL and currency parameters, the app can convert between any two currencies supported by the API.
