Introduction

Pagination is a crucial feature in many web applications, allowing users to navigate through large datasets in a manageable and user-friendly way. In this article, we will explore how to add pagination to your application using a server-side approach, handling search and pagination with URL search parameters, and utilizing the useRouter router hook for smoother client-side transitions.

Why Server-Side Pagination?

When it comes to pagination, it's essential to fetch data on the server rather than on the client. This approach has several benefits, including:

Security: By fetching data on the server, you avoid exposing your database secrets to the client-side code. This is particularly important when using a Client Component, as you don't want to risk exposing sensitive information.
Scalability: Server-side pagination allows you to handle large datasets more efficiently, as the server can handle the data processing and return only the necessary pages to the client.
Improved Performance: By reducing the amount of data transferred between the client and server, you can improve the overall performance of your application.

Handling Search and Pagination with URL Search Parameters

To handle search and pagination with URL search parameters, you can use a library like query-string to parse and manipulate the URL query string. This approach allows you to keep the search and pagination state separate from the client-side state, making it easier to manage and persist the data.

Fetch Data on the Server

To fetch data on the server, you can use a library like express to create a server-side API. This API can handle requests for specific pages of data, taking into account the search and pagination parameters.

Using the `useRouter` Router Hook

The useRouter router hook is a powerful tool for managing client-side routing in your application. By using this hook, you can create a seamless navigation experience for your users, with smooth transitions between pages.

Implementing Pagination

To implement pagination, you'll need to create a component that displays the pagination controls, such as page numbers and navigation links. You can use a library like react-pagination to simplify the process.

Here's an example of how you might implement pagination using the useRouter router hook:

import { useRouter } from 'next/router';
import Pagination from '../components/Pagination';

function MyComponent() {
  const router = useRouter();
  const { page, search } = router.query;

  // Fetch data from the server based on the search and pagination parameters
  const data = await fetchData(page, search);

  return (
    <div>
      <Pagination
        page={page}
        search={search}
        data={data}
        onChange={(newPage, newSearch) => {
          router.push({
            pathname: '/my-component',
            query: { page: newPage, search: newSearch },
          });
        }}
      />
    </div>
  );
}

In this example, we're using the useRouter hook to get the current page and search parameters from the URL query string. We're then passing these parameters to the fetchData function to retrieve the data from the server. Finally, we're rendering the Pagination component, passing it the current page, search parameters, and data.

Conclusion

Adding pagination to your application is a crucial step in providing a user-friendly and manageable experience for your users. By using a server-side approach, handling search and pagination with URL search parameters, and utilizing the useRouter router hook, you can create a seamless navigation experience for your users. Remember to keep your database secrets secure and handle large datasets efficiently to ensure the best possible performance for your application.

Example Use Cases

E-commerce Website: An e-commerce website can use pagination to display a large number of products, allowing users to navigate through the products and find what they're looking for.
Blog Website: A blog website can use pagination to display a large number of articles, allowing users to navigate through the articles and find what they're interested in.
Social Media Platform: A social media platform can use pagination to display a large number of posts, allowing users to navigate through the posts and engage with their friends and followers.

Best Practices

Use a server-side approach: Fetch data on the server rather than on the client to ensure security and scalability.
Handle search and pagination with URL search parameters: Keep the search and pagination state separate from the client-side state to make it easier to manage and persist the data.
Use the useRouter router hook: Create a seamless navigation experience for your users with smooth transitions between pages.
Implement pagination controls: Display pagination controls, such as page numbers and navigation links, to allow users to navigate through the data.
