我想在没有参数的情况下将路由设置为参数 - next.js

Question

I have a NEXTJS project and I Use SSR to fetch data, but I want to make such thing:

When users are on the "/" route, I show them a random product detail page, but when they search for some product and click on it, they should be redirected to eg '/product-01'.

I know how I can take random products, don't think about that, I have a problem with routes, I want to make this route functional on one page.js file

finally, the question is: how can use the next.js route if the route param is just empty?

Answer 1

In Nextjs is you check for a router parameter if it exists then it will return you value of the param or it param does not exists then it will return undefined . for example suppose we have product=productname then we will check router.query.product if url have that perameter than will be return productname if not than it will return undefined so you can place check of undefined to check empty parameter case.
