How can you achieve dynamic route-based code splitting without using getServerSideProps in Next.js?
Here are two effective ways to achieve dynamic route-based code splitting in Next.js without relying on getServerSideProps
:
1. Dynamic Imports with next/dynamic
:
- Utilize
next/dynamic
to wrap components that you want to load lazily based on route parameters or other conditions. - When the wrapped component is required for rendering, Next.js automatically fetches its code and dependencies in a separate chunk, reducing initial load time.
Javascript
import dynamic from 'next/dynamic' ; const BlogPost = dynamic(() => import( '../components/BlogPost' ), { loading: () => <p>Loading post...</p>, }); function BlogPage({ postId }) { // ...fetch post data... return <BlogPost post={postData} />; } export default BlogPage; |
2. Client-Side Rendering (CSR) with Router:
- Employ Next.js’s
router
object within a client-side rendered component to handle navigation and dynamic route loading. - When a user navigates to a route that hasn’t been loaded yet, the JavaScript code for that route is fetched and executed on the client-side.
Javascript
import { useRouter } from 'next/router' ; function BlogPage() { const router = useRouter(); const { postId } = router.query; // ...fetch post data based on postId... return <div>...</div>; } export default BlogPage; |

10. Explain the concept of dynamic routing in Next JS:
Next.js uses a client-side navigation approach that leverages the HTML5 History API. This enables smooth transitions between pages on the client side without a full page reload. The framework provides a built-in Link component that facilitates client-side navigation, and it supports both traditional anchor () tags and programmatically navigating through the next/router module....
