How to implement a toast notification system in Next.js

Implementing a toast notification system in a Next.js application can be achieved using third-party libraries that provide pre-built components and functionality for displaying toast messages. One popular library for this purpose is react-toast-notifications. Here's a step-by-step guide on how to implement a toast notification system in a Next.js application using this library:

1. Create a Next.js App: If you haven't already, create a new Next.js app using the following commands:

   bashCopy code
   npx create-next-app my-toast-app
   
   cd my-toast-app
   

2. Install react-toast-notifications: Install the react-toast-notifications library using npm or yarn:

   bashCopy code
   npm install react-toast-notifications
   # or
   yarn add react-toast-notifications
   

3. Create a Toast Component: Create a new component for your toast notifications. For example, create a file named Toast.js:

   jsxCopy code
   import React from 'react';
   import { useToasts } from 'react-toast-notifications';
   
   const Toast = ({ content }) => {
     const { addToast } = useToasts();
   
     const showToast = () => {
       addToast(content, { appearance: 'success', autoDismiss: true });
     };
   
     return (
       <div>
         <button onClick={showToast}>Show Toast</button>
       </div>
     );
   };
   
   export default Toast;
   

4. Integrate Toast Component: Integrate the Toast component into your pages or components where you want to display toast notifications. For example, in your pages/index.js:

   jsxCopy code
   import React from 'react';
   import Toast from '../components/Toast';
   
   const Home = () => {
     return (
       <div>
         <h1>Next.js Toast Notifications</h1>
         <Toast content="Hello, this is a toast message!" />
       </div>
     );
   };
   
   export default Home;
   

5. Wrap Your App with ToastProvider: In your _app.js or _app.tsx file, wrap your entire app with the ToastProvider to make the toast notifications available throughout the app:

   jsxCopy code
   import { ToastProvider } from 'react-toast-notifications';
   
   function MyApp({ Component, pageProps }) {
     return (
       <ToastProvider>
         <Component {...pageProps} />
       </ToastProvider>
     );
   }
   
   export default MyApp;
   

6. Style Toast Notifications (Optional): You can customize the appearance of the toast notifications by adding your own styles. Check the documentation of react-toast-notifications for more information on customization.

7. Run Your Next.js App: Start your Next.js app and see the toast notifications in action:

   bashCopy code
   npm run dev
   # or
   yarn dev
   

Now, when you click the "Show Toast" button, a toast notification should appear on your page. You can customize the appearance and behavior of the toast notifications by referring to the react-toast-notifications documentation: https://www.npmjs.com/package/react-toast-notifications
