Summary  
This chapter explains how to group related components under a single wrapper and leverage React’s Suspense with a skeleton fallback to optimize asynchronous data fetching and avoid jarring visual loading effects.  

General domain of usage  
Web user interface development

What about the `Card` components, should we add the laoder for each card or how to handle this component. 

When fetching data for individual `<Card>` components, a potential issue arises - loading each card separately may cause a *popping effect* as they load in. This sudden visual change can be jarring for users.

To mitigate this problem, consider the following steps in the `page.tsx` file.

## Back to the Project
- Delete the `<Card>` components;
- Delete the `fetchCardData()` function;
- Import a new wrapper component called `<CardWrapper />`;
- Import a new skeleton component called `<CardsSkeleton />`;
- Wrap `<CardWrapper />` in `Suspense`.

- Navigate to `app/ui/dashboard/cards.tsx`;
- Import `fetchCardData()`;
- Invoke `fetchCardData()` inside the `<CardWrapper/>` component;
- Uncomment necessary code.

Learn to build modern, high-performance web applications using Next.js. Set up projects with structured layouts, styling, and routing for seamless navigation. Fetch and display data efficiently while optimizing rendering and performance. Implement advanced features like pagination, CRUD operations, and global search for dynamic web apps. Deploy your Next.js projects and connect them with databases, and add authentication to protect user data.

Let's discuss what you need to learn before diving into the Next.js framework, what to expect from this course, and what you'll build.

We will set up the project, inspect ways to add styling to our app and cover visual aspects such as images, fonts, pages, and layouts.

Learn how to easily create and manage a new view for your app and navigate through all pages seamlessly with an incorporated routing system.

Deploy the Next.js app using GitHub and Vercel accounts. Additionally, establish a database to supply the app with the necessary data.

Consider how to obtain and show data to the user clearly and efficiently.
