How do I install SweetAlert2 in a React project?

Run npm install sweetalert2 or yarn add sweetalert2. Then import Swal from 'sweetalert2' in any component. For React-specific bindings, also install sweetalert2-react-content via npm install sweetalert2-react-content.

Can SweetAlert2 handle async operations like API calls in React?

Yes. Use the preConfirm option inside Swal.fire() to return a Promise. SweetAlert2 will show a loading state automatically while your async function (e.g., an axios POST) resolves or rejects.

How do you use SweetAlert2 with React hooks and functional components?

Create a custom hook — e.g., useConfirm() — that wraps Swal.fire() and returns a Promise. Call it inside event handlers or useEffect. This pattern keeps your component logic clean and fully testable.
