Prisma Client API

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.

• 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
7	Raw SQL	CRITICAL	raw-queries
8	Client Methods	MEDIUM	client-methods

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
