Prisma 7 ORM

Rust-free TypeScript ORM with 90% smaller bundles and 3x faster queries.

Agent Workflow (MANDATORY)

Before ANY implementation, use TeamCreate to spawn 3 agents:

1. fuse-ai-pilot:explore-codebase - Analyze existing schema and database patterns
2. fuse-ai-pilot:research-expert - Verify latest Prisma 7 docs via Context7/Exa
3. mcp__context7__query-docs - Check breaking changes and migration guide

After implementation, run fuse-ai-pilot:sniper for validation.

Overview

When to Use

• Database access in Next.js 16 applications
• Type-safe queries with full TypeScript inference
• Schema-first database modeling and migrations
• Complex queries requiring TypedSQL
• Excluding sensitive fields with Omit API

Why Prisma 7

Feature	Benefit
Rust-free client	90% smaller bundles (14MB → 1.6MB)
Query performance	Up to 3x faster on large datasets
ESM-first	Native ES modules, modern architecture
TypedSQL	Type-safe raw SQL queries
Omit API	Exclude sensitive fields globally
Driver adapters	Direct database driver integration

Breaking Changes from v6

Critical Migration Points

Change	v6	v7
Provider	prisma-client-js	prisma-client
Output path	Optional	REQUIRED
Import	@prisma/client	./generated/prisma/client
Drivers	Built-in	Adapter required
Config	Schema only	prisma.config.ts

Required Schema Changes

Provider must be prisma-client with explicit output path. No more generation to node_modules.

Driver Adapters Required

PostgreSQL requires @prisma/adapter-pg, MySQL requires @prisma/adapter-mariadb, SQLite requires @prisma/adapter-better-sqlite3.

---

SOLID Architecture

Module Structure

Database code organized in modules/cores/db/:

• modules/cores/db/prisma.ts - Singleton PrismaClient
• modules/cores/db/generated/ - Generated client
• prisma/schema.prisma - Schema definition
• prisma/migrations/ - Migration history
• prisma.config.ts - Prisma configuration

File Organization

File	Purpose	Max Lines
prisma.ts	Singleton client	30
schema.prisma	Models, relations	100 per section
seed.ts	Database seeding	50

---

Key Concepts

Singleton Pattern (Next.js)

Prevent multiple PrismaClient instances during hot-reload. Use globalThis to cache instance in development.

Output Path

Generated client goes to custom path, not node_modules. Import from generated folder.

Driver Adapters

Direct database driver integration for better performance and control. Configure connection pooling at driver level.

TypedSQL

Write raw SQL with full type safety. Results are typed based on query.

Omit API

Exclude fields globally or per-query. Perfect for passwords and sensitive data.

Best Practices

1. Singleton in Next.js - Cache PrismaClient in globalThis
2. Output path required - Never generate to node_modules
3. Driver adapters - Use native drivers for better performance
4. Omit sensitive fields - Configure global omit for passwords
5. TypedSQL for complex - Use for queries Prisma can't express
6. Index verification - Check query plans for N+1 issues

Forbidden Patterns

Pattern	Reason	Alternative
Import from @prisma/client	v7 requires generated path	Import from ./generated/prisma/client
prisma-client-js provider	Deprecated in v7	Use prisma-client
No output path	Required in v7	Set output in generator
MongoDB	Not supported in v7.0-7.3	Stay on Prisma 6
url in datasource	Deprecated	Use prisma.config.ts
