What is Prisma ORM?
TL;DR
Type-safe database toolkit that provides an intuitive API for PostgreSQL operations with automatic TypeScript types.
Prisma is the database ORM (Object-Relational Mapping), offering type-safe database access with zero boilerplate and AI-friendly schema definitions.
Core Features:
1. Schema Definition:
// prisma/schema.prisma
model User {
id String @id @default(cuid())
email String @unique
name String?
posts Post[]
createdAt DateTime @default(now())
}
model Post {
id String @id @default(cuid())
title String
content String?
author User @relation(fields: [authorId], references: [id])
authorId String
}
2. Type-Safe Queries:
// Automatic TypeScript types generated
const user = await prisma.user.findUnique({
where: { email: 'user@example.com' },
include: { posts: true }
});
// user is fully typed with User & { posts: Post[] }
3. Migrations:
- Automatic migration generation: npx prisma migrate dev
- Version-controlled database schema changes
- Rollback support for production safety
AI-Friendly Design:
Prisma's schema is declarative and human-readable, making it perfect for AI-native development:
- AI tools instantly understand relationships
- Schema modifications are clear and predictable
- Type generation eliminates guesswork
- Query API is self-documenting
