Prisma

Prisma 6 (2025) adds multi-schema support and Edge support (Cloudflare Workers) via driver adapters. It is known for its type-safe client.

When to Use

• TypeScript: The PrismaClient generated types are unmatched.
• Relational DBs: Postgres, MySQL, SQL Server.
• Productivity: schema.prisma is an easy-to-read source of truth.

Core Concepts

Schema (schema.prisma)

Defines models and relationships.

Prisma Client

Auto-generated query builder. prisma.user.findMany().

Migrate

Declarative migrations. prisma migrate dev.

Best Practices (2025)

Do:

• Use Driver Adapters: For serverless/edge environments (@prisma/adapter-neon).
• Use relationMode = "prisma": If utilizing PlanetScale or Vitess.
• Check generated SQL: Use $on('query') to verify performance.

Don’t:

• Don’t N+1: Be careful with nested reads inside loops. Use include.
