0:00 All right, so in this latest lecture, we've updated all of our dependencies in 0:03 our 0:04 Prisma branch, and this includes Prisma at V seven. 0:08 Now, Prisma V seven introduces a few breaking 0:10 changes to how we've 0:12 previously configured Prisma. And so in this lecture, we're gonna walk 0:15 through these changes to see how you can upgrade your application. 0:19 So I'm gonna leave a link below to these changes to the repository 0:22 that show you the exact changes we made in this commit, so you can review all of 0:26 them, but let's go ahead and jump in to see the changes. 0:30 Now, the primary change here in Prisma is if we go to Auth, for 0:34 example, where we know we have Prisma set up, 0:37 you'll notice that we now have a new file called 0:40 prisma.config.ts here at the root. 0:44 Now, in Prisma V seven, we have this new file, which 0:46 is sort of like 0:47 Drizzle config, if you've used Drizzle before, 0:49 where we define 0:51 configuration inside of TypeScript directly. 0:54 So you can see here we're importing dot env, which is the actual 0:58 library that NestJS config uses under the hood to load environment 1:02 variables. And so this is the default configuration we import 1:06 from Prisma config. Define this config 1:09 file where we define the path to our schemas, 1:13 the path to our migrations, 1:16 and finally, data source where we actually provide the 1:19 database 1:20 connection URL. 1:22 Now, you can use the env function from Prisma, 1:24 which will use dot env under the 1:26 hood to extract an environment variable. 1:28 So in this case, we're extracting our database URL, 1:32 which we know we've set 1:32 up to point to our PostgreSQL DB. Now, importantly, there are some 1:36 additional dependencies we need for this Prisma seven integration. 1:41 So make sure you have pg installed, which is a Node
