0:00 Okay, so we're ready to actually go into our 0:02 user service and 0:04 start implementing our CRUD functionality for the user, 0:08 starting off with the first route we know we have to actually create the user, 0:12 and now we can actually utilize the Prisma client types that the library 0:16 has generated for us based off of the schema we know we have. 0:20 So the first step is going to be able to actually provide the database 0:24 connection as an injectable dependency to our user 0:28 service. 0:29 Now, in the schema Prisma file, we've already provided the Prisma client 0:33 library with the information on how to connect to our database, so 0:37 the actual connection to the database has been abstracted away from us and is all 0:41 configured using this common schema Prisma file. 0:45 So we need a way to actually expose this Prisma client JS 0:49 library with our connection and all of our types to our 0:53 NestJS application. To do this, I'm gonna go ahead and 0:56 generate a new module for our app. So let's go ahead and 1:01 nest generate module prisma. 1:06 So this is gonna go ahead and create a Prisma module, 1:09 and let's go also ahead 1:10 and create a service for Prisma. So this is gonna be the 1:14 common Prisma service that we can inject in our other services 1:18 to 1:18 actually use the database. 1:20 So now we can see we have the Prisma folder, and inside we have the Prisma 1:24 module that's providing the Prisma service. 1:28 This has also been added to our root app module here as an 1:31 import. However, we don't actually need this at the root, 1:35 so let's go 1:35 ahead and remove it, 1:39 since we're gonna be importing it in the modules we actually need it in. 1:44 So now let's go back to the Prisma service and start filling this out.
