Next.js - Routing
Next.js uses file system based router. Whenever we add any page to pages directory, it is automatically available via url. Following are the rules of this router.
Index Routes − An index.js file present in a folder maps to root of directory. For example −
pages/index.js maps to '/'.
pages/posts/index.js maps to '/posts'.
Nested Routes − Any nested folder structure in pages directory because router url automatically. For example −
pages/settings/dashboard/about.js maps to '/settings/dashboard/about'.
pages/posts/first.js maps to '/posts/first'.
Dynamic Routes − We can use named parameter as well to match url. Use brackets for the same. For example −
pages/posts/[id].js maps to '/posts/:id' where we can use URL like '/posts/1'.
pages/[user]/settings.js maps to '/posts/:user/settings' where we can use URL like '/abc/settings'.
pages/posts/[...all].js maps to '/posts/*' where we can use any URL like '/posts/2020/jun/'.
Page Linking
Next.JS allows to link pages on client side using Link react component. It has following properties −
href − name of the page in pages directory. For example /posts/first which refers to first.js present in pages/posts directory.
Let's create an example to demonstrate the same.
In this example, we'll update index.js and first.js page to make a server hit to get data.
Let's update the nextjs project used in Global CSS Support chapter.
Update index.js file in pages directory as following.
import Link from 'next/link'
import Head from 'next/head'
function HomePage(props) {
return (
<>
<Head>
<title>Welcome to Next.js!</title>
</Head>
<div>Welcome to Next.js!</div>
<Link href="/posts/first">> <a>First Post</a></Link>
<br/>
<div>Next stars: {props.stars}</div>
<img src="/logo.png" alt="TutorialsPoint Logo" />
</>
)
}
export async function getServerSideProps(context) {
const res = await fetch('https://api.github.com/repos/vercel/next.js')
const json = await res.json()
return {
props: { stars: json.stargazers_count }
}
}
export default HomePage
Start Next.js Server
Run the following command to start the server −.
npm run dev > nextjs@1.0.0 dev \Node\nextjs > next ready - started server on http://localhost:3000 event - compiled successfully event - build page: / wait - compiling... event - compiled successfully event - build page: /next/dist/pages/_error wait - compiling... event - compiled successfully
Verify Output
Open localhost:3000 in a browser and you will see the following output.
Click on First post link.
