Prisma Client API Reference

Complete API reference for Prisma Client. This skill provides guidance on model queries, filtering, relations, and client methods for current Prisma projects.

When to Apply

Reference this skill when:

• Writing database queries with Prisma Client
• Performing CRUD operations (create, read, update, delete)
• Filtering and sorting data
• Working with relations
• Using transactions
• Configuring client options

Rule Categories by Priority

Priority	Category	Impact	Prefix
1	Client Construction	HIGH	constructor
2	Model Queries	CRITICAL	model-queries
3	Query Shape	HIGH	query-options
4	Filtering	HIGH	filters
5	Relations	HIGH	relations
6	Transactions	CRITICAL	transactions

Quick Reference

• constructor - PrismaClient setup, adapter wiring, logging, and SQL commenter plugins
• model-queries - CRUD operations and bulk operations
• query-options - select, include, omit, sort, pagination
• filters - scalar and logical filter operators
• relations - relation reads and nested writes
• transactions - array and interactive transaction patterns
• raw-queries - $queryRaw and $executeRaw safety
• client-methods - lifecycle methods, extensions, and satisfies patterns for prisma-client

Client Instantiation

import { PrismaClient } from '../generated/client'
import { PrismaPg } from '@prisma/adapter-pg'

const adapter = new PrismaPg({
  connectionString: process.env.DATABASE_URL
})

const prisma = new PrismaClient({ adapter })

Quick Examples

Find records

// Find by unique field
const user = await prisma.user.findUnique({
  where: { email: 'alice@prisma.io' }
})

// Find with filter
const users = await prisma.user.findMany({
  where: { role: 'ADMIN' },
  orderBy: { createdAt: 'desc' },
  take: 10
})

Create records

const user = await prisma.user.create({
  data: {
    email: 'alice@prisma.io',
    name: 'Alice',
    posts: {
      create: { title: 'Hello World' }
    }
  },
  include: { posts: true }
})

Update records

const user = await prisma.user.update({
  where: { id: 1 },
  data: { name: 'Alice Smith' }
})

Delete records

await prisma.user.delete({
  where: { id: 1 }
})

Transactions

const [user, post] = await prisma.$transaction([
  prisma.user.create({ data: { email: 'alice@prisma.io' } }),
