How do I implement nested routes in Next.js?

How do I implement nested routes in Next.js?

To implement nested routes in Next.js, you can create a folder structure that reflects your desired route hierarchy. For example, if you want a route like /blog/post, you would create a folder named blog and inside it, create a file named post.js.

Can you show me an example of the folder structure?

Sure! Your folder structure would look like this:

/pages
  └── blog
      └── post.js

This way, Next.js will automatically handle the routing for you.

What if I want to add dynamic routes?

For dynamic routes, you can use square brackets in your file name. For example, to create a dynamic post route, you would name your file [id].js inside the blog folder. This allows you to access the post ID via the URL.

How do I fetch data for these dynamic routes?

You can use Next.js's getStaticProps or getServerSideProps functions to fetch data for your dynamic routes. These functions allow you to fetch data at build time or request time, respectively.
