How can I use Next.js with generators?
You can use generators in Next.js to create dynamic routes and handle data fetching efficiently. Would you like a code example?
Yes, please provide a code example.
Sure! Here's a simple example:
// pages/posts/[id].js
import { useRouter } from 'next/router';
const Post = ({ post }) => {
return <div>{post.title}</div>;
};
export async function getStaticPaths() {
const res = await fetch('https://api.example.com/posts');
const posts = await res.json();
const paths = posts.map(post => ({ params: { id: post.id.toString() } }));
return { paths, fallback: false };
}
export async function getStaticProps({ params }) {
const res = await fetch(`https://api.example.com/posts/${params.id}`);
const post = await res.json();
return { props: { post } };
}
export default Post;
What does getStaticPaths do in this example?
getStaticPaths
generates the paths for dynamic routes at build time, allowing Next.js to pre-render pages for each post.
