React-fetch and Whatwg-fetch are both libraries for making HTTP requests in a React application, but they are used for different purposes and have different features.
React–fetch: react-fetch is a library that provides a higher-order component (HOC) for fetching data and handling errors in a React application. It allows you to wrap your components with the withFetch HOC, which provides a data prop that contains the data fetched from the server, and a status prop that indicates the status of the fetch request. It also allows you to handle errors in a centralized way. This means that you can define a single error-handling function that will be called when an error occurs during the fetch request, and this function will be passed down to all wrapped components through props.
Example:
Javascript
import withFetch from 'react-fetch'; class MyComponent extends React.Component { render() { if (this.props.status === 'loading') { return <div>Loading...</div>; } if (this.props.status === 'error') { return <div>Error: {this.props.error.message}</div>; } return <div>Data: {this.props.data}</div>; } } const MyFetchingComponent = withFetch(MyComponent, { method: 'GET', }); |
Whatwg-fetch: It is a library that provides a minimal polyfill for the fetch API, which is a modern standard for making HTTP requests in JavaScript. The Fetch API provides an interface for fetching resources (including across the network). It will seem familiar to anyone who has used XMLHttpRequest, but the new API provides a more powerful and flexible feature set. It allows you to use the fetch function to make requests, and it returns a promise that resolves with a Response object, which contains the data and headers of the response. You can then use the json() method on the response object to parse the response as json.
Example:
Javascript
.then(response => response.json()) .then(data => { console.log(data); }); |
Difference between React-fetch and Whatwg-fetch:
- React-fetch is a library that provides a higher-order component (HOC) for fetching data and handling errors in a React application. It allows you to wrap your components with the withFetch HOC, which provides a data prop that contains the data fetched from the server, and a status prop that indicates the status of the fetch request.

- Whatwg-fetch is a library that provides a minimal polyfill for the fetch API, which is a modern standard for making HTTP requests in JavaScript. It allows you to use the fetch function to make requests, and it returns a promise that resolves with a Response object, which contains the data and headers of the response. It allows you to handle errors by chaining a .catch method to the promise.
