Implementing Union Types in Prisma

Prisma currently lacks direct support for union types. To model this, follow similar practices as seen in platforms like Facebook's feed. Implement distinct tables for each entity type and use inheritance or a shared identifier for relation.

Steps to achieve union types in Prisma:

generator client { 
  provider = "prisma-client-js"
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

model Video {
  id    Int    @id @default(autoincrement())
  url   String
  media String
}

model Photo {
  id     Int @id @default(autoincrement())
  width  Int
  height Int
}

model Post {
  id      Int    @id @default(autoincrement())
  message String
}

model Activity {
  id   Int @id @default(autoincrement())
  type String // 'video', 'photo', 'post'
}

By using separate tables with a common 'Activity' model as the relational hub, each entity can be queried efficiently. While Prisma does not inherently support unions, this approach ensures scalable management of various data types akin to union functionality.
