Development of a NestJS module for product management. The process includes using the Nest CLI to generate files, defining DTOs for data validation, implementing a controller with JWT authentication, and integrating the Prisma service for database persistence. The workflow concludes with testing the POST endpoint via Postman.

0:00 All right, so let's go ahead and get started by creating a new module 0:04 specifically just for our new products. 0:07 So I'll use the Nest CLI as we've done before. 0:10 Go ahead and open up the terminal and run Nest generate module 0:15 products. Go ahead and generate a products module. 0:19 That will also update our app.module to import it in the 0:22 root of our project here. 0:25 So now that we have the products module, let's use the Nest CLI to also 0:29 generate a controller, which we're going to utilize to 0:33 accept HTTP requests for our products, 0:37 and finally, a service as well, which we're going to inject our 0:41 Prisma client into to actually persist and read our products. 0:46 So just like that, we have a full-fledged products module 0:49 with a products 0:50 controller and a product service. 0:53 So these are empty right now. Our products controller is prefixed with 0:57 products as I expect, and the product service is empty. 1:01 Let's go ahead and start filling out our products controller with our first 1:05 route to actually be able to create a product. 1:08 So let's go ahead and create this post route, 1:11 decorate it with 1:12 @post, and I'm also going to use our JWT 1:16 Auth Guard in order to protect this route from unauthenticated 1:20 users. So only authenticated users with a valid 1:23 JWT will be able to access this route. 1:27 To do this, we're going to use useGuards 1:31 and pass in the JWT_AUTH_GUARD, which is gonna 1:34 require the request to have the JWT cookie. 1:38 So we'll have async createProduct function. 1:42 And now I want to go ahead and extract a body 1:46 from the incoming request, which is gonna be the create product request. 1:50 Let's go ahead and define this as a DTO. 1:53 So I'll create a DTO folder as data transfer object, 1:58 and we can create the
