Hi @meager gate. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

To set up Prisma in your Next.js application, you can follow these steps:

1. Install Prisma CLI: Start by installing the Prisma CLI via npm:

   npm install prisma --save-dev
   

   Source: Vercel Guide (https://vercel.com/guides/nextjs-prisma-postgres)

2. Create Prisma Schema: Create a prisma folder and add a file called schema.prisma. This is your main Prisma configuration file that will contain your database schema. Add your model definitions to your schema.prisma.

   // schema.prisma
   generator client { provider = "prisma-client-js"}
   datasource db { provider = "postgresql" url = env("POSTGRES_PRISMA_URL") // uses connection pooling directUrl = env("POSTGRES_URL_NON_POOLING") // uses a direct connection}
   model Post { id String @default(cuid()) @id title String content String? published Boolean @default(false) author User? @relation(fields: [authorId], references: [id]) authorId String?}
   model User { id String @default(cuid()) @id name String? email String? @unique createdAt DateTime @default(now()) @map(name: "created_at") updatedAt DateTime @updatedAt @map(name: "updated_at") posts Post[] @@map(name: "users")}

3. Create Database Tables: Use the Prisma CLI to create the tables in your database:

   npx prisma db push

4. Install Prisma Client: Install Prisma Client in your app via npm:

   npm install @prisma/client
   

   Source: Vercel Guide (https://vercel.com/guides/nextjs-prisma-postgres)

5. Generate Prisma Client: Update your Prisma Client every time your Prisma schema file changes:

   npx prisma generate
   

   Source: Vercel Guide (https://vercel.com/guides/nextjs-prisma-postgres)

6. Create Prisma Client Instance: Create a PrismaClient instance in a prisma.ts file inside the lib/ directory:

   mkdir lib && touch lib/prisma.ts
   

   Add the following code to this file:

   import { PrismaClient } from '@prisma/client';
   let prisma: PrismaClient;
   if (process.env.NODE_ENV === 'production') { prisma = new PrismaClient();} else { if (!global.prisma) { global.prisma = new PrismaClient(); } prisma = global.prisma;}
   export default prisma;

Now, whenever you need access to your database you can import the prisma instance into the file where it's needed.

Let me check the knowledge base for you. One moment! :books:

You can host your Prisma database on Vercel Postgres. To do this, you need to follow the instructions in the Postgres quickstart (https://vercel.com/docs/storage/vercel-postgres/quickstart) guide.

Once you've set up your database, you can get the connection URL from your Vercel environment variables. The connection URL will be in the following format:

postgresql://USER:PASSWORD@HOST:PORT/DATABASE?schema=SCHEMA

For example, if you're using a local PostgreSQL database, your connection string might look like this:

postgresql://janedoe:mypassword@localhost:5432/notesapi?schema=public

You can then use this connection URL in your schema.prisma file to connect your Next.js application to your database.
