Next Js Bangla Tutorial: Nested Routes and Dynamic Route | Part 4

In the previous parts of this tutorial series, we have learned the basics of Next.js and how to set up a project. In this part, we will dive deeper into Next.js routing and explore nested routes and dynamic routes.

Nested Routes

Nested routes refer to the concept of having routes within routes. This allows for more complex routing structures in a Next.js project. To create nested routes, you can create a directory within the `pages` directory with the name of the parent route. Inside this directory, you can create another file for the nested route with the name of the nested route.

For example, if you have a route `/products` and want to create a nested route `/products/123`, you can create a directory `products` within the `pages` directory and create a file `123.js` inside it. The URL for this nested route will be `/products/123`.

Dynamic Route

A dynamic route in Next.js allows you to create routes that can accept parameters or variables in the URL. This is useful for creating dynamic pages or pages that need to be fetched based on a specific ID or value.

To create a dynamic route, you can create a file in the `pages` directory with square brackets `[]` in the filename. For example, to create a dynamic route `/products/:id`, you can create a file `[id].js` in the `pages` directory. You can access the value of the parameter `id` in this file using `useRouter` hook provided by Next.js.

Next.js provides a flexible and powerful routing system that allows you to create complex and dynamic routes for your web applications. By understanding nested routes and dynamic routes, you can create more advanced features and functionalities in your Next.js projects.

Stay tuned for the next part of this tutorial series where we will cover more advanced topics in Next.js. Happy coding!
