The developer implements dynamic routing in a Next.js application to display individual product pages. This involves creating file-based routes with path parameters, updating the Nest.js back-end to fetch specific products, refactoring static asset paths for images, and handling errors with 404 status codes.

0:00 All right, so next up, I wanna add support to actually be able to 0:04 click 0:04 on a individual product and navigate to that single 0:08 product page. 0:10 So to do this, we're gonna take advantage of dynamic 0:13 routing in Next.js using path parameters. 0:17 So the way we're gonna do this is since we're using the app directory 0:20 approach, we're gonna follow this consistent 0:24 file-based naming convention that we've already been using. 0:27 For example, using our layout.tsx, we know we have 0:31 shared layouts between our child components, and then we have 0:35 the actual page themselves based off of the 0:39 page.tsx, and this corresponds to the actual file 0:43 system folder structure here. So we're gonna do the same thing to create 0:47 a 0:47 new individual product route. So our URL is gonna 0:51 be /products and then the product ID to navigate to 0:55 that individual product. To represent this in our file structure 0:59 here, 0:59 we know we're gonna go inside of the products folder, which will correspond to 1:03 /products in the URL. And then to actually create 1:07 a dynamic URL where we can actually extract a path 1:11 parameter from it, we simply create a new folder, and we use 1:14 this bracket notation, and inside of here is going to be the 1:18 actual path parameter. So in our case, this is going to be the 1:22 product ID that we're extracting from the URL. 1:26 Create a page.tsx inside of 1:30 the product ID folder. So this is going to be the actual 1:34 JSX that gets rendered when we navigate to a single product 1:38 ID at /products, product ID. And 1:41 now let's go ahead and export a component 1:45 singleProduct. 1:47 So this is gonna be our singleProduct component. 1:50 And for now, let's just go ahead and return 1:54 some dummy JSX and say, "Single 1:58 product" so we know that this component's working properly.
