How do I create dynamic routes in Next.js?

To create dynamic routes in Next.js, you can use the file system-based routing feature. Create a folder named pages and inside it, create a file with square brackets, like [id].js, where id is a dynamic segment.

Can you give me an example of how to implement this?

Sure! If you have a blog, you can create a file called [slug].js in the pages/posts directory. Then, use getStaticPaths to define the paths that should be pre-rendered.

What about fetching data for these dynamic routes?

You can use getStaticProps in your [slug].js file to fetch data based on the dynamic route. This function runs at build time and allows you to fetch data for each route.
