What are the differences between React Query and React Async?

What are the differences between React Query and React Async?

React Query is a powerful data-fetching library that provides caching, synchronization, and background updates, while React Async is a simpler library focused on handling asynchronous operations with a more straightforward API.

Which one should I use for my project?

It depends on your project's needs. If you require advanced features like caching and automatic refetching, React Query is the better choice. For simpler use cases, React Async might be sufficient.

Can you give me an example of how to use React Query?

Sure! Here's a basic example: you can use the useQuery hook to fetch data. For instance:

import { useQuery } from 'react-query';

const { data, error, isLoading } = useQuery('todos', fetchTodos);

This will fetch the todos and manage loading and error states for you.

What about error handling in React Async?

In React Async, you can handle errors using the onError callback in the Async component. For example:

<Async promise={fetchData()} onError={handleError}>
  {({ data }) => <div>{data}</div>}
</Async>
