// This is your Prisma schema file,
// learn more about it in the docs: https://pris.ly/d/prisma-schema

// 1. Define the database connection
datasource db {
  provider = "postgresql" // Or "mysql" if you decide to switch
  url      = env("DATABASE_URL")
}

// 2. Define the Prisma Client generator
generator client {
  provider = "prisma-client-js"
}

// 3. Define your data models
