React Toastify is a popular library for displaying toast notifications in a React application. Here's a step-by-step guide on how to connect React Toastify to your React application:

Install React Toastify using npm or yarn:

npm install react-toastify

or

yarn add react-toastify

Import the necessary components from React Toastify into your React application:

import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';

Render the ToastContainer component in your React application:

function App() {
  return (
    <div>
      <ToastContainer />
      ...
    </div>
  );
}

Use the toast function to display a notification:

function handleClick() {
  toast('Hello World!');
}

function App() {
  return (
    <div>
      <ToastContainer />
      <button onClick={handleClick}>Click Me</button>
    </div>
  );
}

Customize the notification by passing options to the toast function:

function handleClick() {
  toast.success('Hello World!', {
    position: toast.POSITION.TOP_RIGHT
  });
}

function App() {
  return (
    <div>
      <ToastContainer />
      <button onClick={handleClick}>Click Me</button>
    </div>
  );
}
