Integrating APIs with React
The React library is widely used to create user interfaces in JavaScript. You can make UI components that are both reusable and easy to maintain with React’s component-based architecture.
By using this approach, developers may more easily incorporate APIs, making it easier for components to retrieve and show data. For dynamic apps that depend on real-time data from APIs like Fixer API, React is a great option because its virtual DOM guarantees quick updates and rendering.
Here we will demonstrate how to incorporate an APILayer into a React application.
Example API: Fixer API
Based on 15+ exchange rate data sources, the Fixer API provides real-time exchange rates for 170 currencies. Each API endpoint serves a particular purpose. Endpoint functions include collecting the current exchange rate data for all or a specific set of currencies, converting quantities, retrieving Time-Series data for multiple currencies, and accessing the API for daily fluctuation data. Make sure you get your API Key before you start using Fixer API.
Available Endpoints
- /symbols – Returns all available currencies.
- /latest – Returns real-time exchange rate data for all available or a specific set of currencies.
- /convert – Allows for conversion of any amount from one currency to another.
- /{date} – Returns historical exchange rate data for all available or a specific set of currencies.
- /timeseries – Returns daily historical exchange rate data between two specified dates for all available or a specific set of currencies.
- /fluctuation – Returns fluctuation data between two specified dates for all available or a specific set of currencies.
