Prisma ORM 実装ガイド（v7のRustフリー化・driver adapters／スキーマ・リレーション設計／Migrate本番運用／Next.js連携／パフォーマンス／技術選定／v6→v7移行）
Prismaは「スキーマを唯一の真実源にして、型・クライアント・マイグレーションをすべて導出する」思想のTypeScript ORMです。2025年11月のv7でRustエンジンが廃止され、driver adapterが必須・generatorがprisma-client・設定がprisma.config.tsへと刷新されました。本クラスタは、v7前提の本番運用（型安全・冪等性・トランザクション・接続管理）を中核に、スキーマとリレーションの設計（参照アクション・relationMode・複合キー）、Migrateの本番運用（dev/deployの分離・既存DBのベースライン・無停止のexpand-and-contract・CI/CD）、Next.js App RouterとServer Actions/Zod境界での結合、計測起点のパフォーマンス最適化（N+1撲滅・select/omit・カーソルページング・接続プール・cacheStrategy）、Drizzle/TypeORM/Kyselyとの技術選定、そしてv6→v7移行までを体系化します。受賞B2B SaaSや本番二重課金0件の決済基盤で型安全とDB運用を徹底した知見を根拠に、Prisma公式ドキュメントに忠実な実コードで、速く・安全に作るデータ層を解説します。RLSやSupabase・Drizzleに特化した設計は『データベース・RLS』クラスタ、PostgreSQL本体の性能・運用は『PostgreSQL本体・性能設計』『PostgreSQL 運用・信頼性』クラスタを参照してください。

Prisma ORM Production-Operations Guide (v7): Rust-Free, driverAdapters, and Type-Safe Schema through Migrations, Transactions, and Serverless
An implementation guide to operating Prisma ORM (v7) in production. The new 'prisma-client' generator and mandatory driver adapters, type generation from the schema, CRUD, relations (avoiding N+1), transactions and idempotency, prisma migrate dev/deploy, the safe use of $queryRaw, Client Extensions, connection management for Next.js/serverless, Prisma Postgres/Accelerate, and how to choose between Drizzle and how to migrate v6→v7—all explained in real code faithful to the official documentation.

Next.js × Prisma production implementation guide: solidify the App Router, Server Components, Server Actions, the Zod boundary, and connection management type-safely
A guide to implementing production-quality data access with Next.js (App Router) and Prisma (v7). Faithful to the official docs, with real code it explains server-only client placement and import 'server-only', direct fetching in Server Components, the double-validation form of Server Actions × Zod × useActionState, cache invalidation with revalidateTag/Path, the dev hot-reload singleton, Node/Edge runtime selection, and avoiding N+1.

Prisma Migrate production-operations guide: the correct dev/deploy separation, shadow DB, baselining an existing DB, zero-downtime expand-and-contract migration, and CI/CD
An implementation guide to safely operating Prisma Migrate (v7) in production. Faithful to the official docs, with real commands it explains the role separation of migrate dev/deploy/reset/diff/resolve, how the shadow DB works, retrofitting onto an existing DB (db pull + baseline), zero-downtime expand-and-contract schema changes that edit SQL with --create-only, drift detection and recovery, migrate deploy in CI/CD, and v7's seed changes.

Prisma v6 → v7 migration guide: safely crossing Rust-free, mandatory driver adapters, the prisma-client generator, prisma.config.ts, and the removal of middleware
An implementation guide to safely migrating Prisma ORM from v6 to v7. With procedures and a checklist per breaking change, it covers: the removal of the Rust engine and mandatory driver adapters, the generator becoming prisma-client (output required, escaping node_modules, import-source change), migrating config to prisma.config.ts, the removal of $use middleware → Client Extensions, Prisma.validator becoming legacy → satisfies, the removal of auto-seeding, and removed CLI flags.

Prisma performance-optimization guide: eliminating N+1, select/omit, cursor paging, connection pools, cacheStrategy, and TypedSQL
An implementation guide to raising Prisma (v7) performance to production quality. Faithful to the official docs, it explains, with real code and a measurement-first optimization order: N+1 avoidance with include/select and the in operator, preventing over-fetching with select and omit (GA), offset vs. cursor paging, aggregation with aggregate/groupBy/_count, connection-pool settings on the driver adapter, Accelerate's cacheStrategy (ttl/swr), and TypedSQL (Preview) for hot paths.

Complete Prisma schema-design & relations guide: design 1:1, 1:N, N:N, referential actions, relationMode, composite keys, and name mapping type-safely
An implementation guide to solidifying Prisma (v7) schema and relation design at production quality. Faithful to the official docs, with real code it explains 1:1/1:N/N:N (implicit and explicit join tables), the onDelete/onUpdate referential actions and their defaults, relationMode (foreignKeys/prisma), the composite constraints @@id/@@unique/@@index, @default functions, native types, self-relations, and mapping to an existing DB with @map/@@map.

Prisma vs Drizzle vs TypeORM vs Kysely — a tech-selection guide: the differences between type-safe TypeScript ORMs/query builders and how to choose (2026)
What to build your TypeScript DB layer with — a tech-selection guide comparing Prisma, Drizzle, TypeORM, and Kysely based on official facts. It organizes schema definition (DSL/code generation vs inference vs decorators), migrations, type-safety approach, edge/lightweightness, maturity, and use-case-by-use-case recommendations into decision axes you won't second-guess on a project, also accounting for Prisma v7 going Rust-free.
