I am looking to create a route with parameters in Next.js, as well as without any parameters

I am working on a NEXTJS project and utilizing SSR for data fetching. However, I am trying to implement the following scenario:

When users land on the "/" route, they should be presented with a random product detail page. But if they search for a specific product and click on it, they should be redirected to a URL like '/product-01'.

I already know how to fetch random products, so please focus solely on helping me with the routing issue. I want to achieve this functionality within a single page.js file.

In conclusion, my question is: How can I utilize the next js route when the route parameter is empty?

Answer №1

When using Next.js, you can verify the existence of a router parameter by checking if it exists. If the parameter is present, it will return the value of the parameter; otherwise, it will return undefined. For instance, let's say we have a product parameter with the value "productname". In this case, we would check router.query.product. If the URL includes that parameter, it will return "productname"; otherwise, it will return undefined. Therefore, you can use a check for undefined to handle cases where the parameter is empty.
