Does Prisma satisfy NHS DTAC data minimisation requirements?

Prisma select syntax is the correct approach for NHS DTAC data minimisation. Instead of Prisma findMany({}) which returns all fields (including NHS patient personal data fields not needed for the specific query), use Prisma select: prisma.patient.findMany({ select: { nhsNumber: true, appointmentDate: true } }) — returns only the two fields needed. UK GDPR Article 25 (privacy by design): data minimisation at query level — only fetch the personal data fields needed for the specific operation. ClickMasters lints all Prisma queries in NHS projects — any findMany or findFirst without an explicit select statement fails the CI/CD pipeline.

When should UK teams switch from TypeORM to Prisma?

Migrate from TypeORM to Prisma when: (1) type safety is causing bugs (TypeORM's decorator-based types miss cases Prisma catches at compile time), (2) migration management is painful (TypeORM migrations require manual SQL writing — Prisma migrate generates SQL from schema diff automatically), (3) new feature development is slow (Prisma DX is significantly faster than TypeORM for common operations). Migration approach: Prisma can introspect existing TypeORM database → generates Prisma schema from existing tables → run Prisma migrate in baseline mode (no change to existing tables). ClickMasters has migrated 12 UK projects from TypeORM to Prisma — typical migration time for a mid-size application: 1–2 weeks.

Direct Answer

Prisma is ClickMasters' default for most UK TypeScript projects: best DX, schema as the source of truth, automatic migrations, and Prisma Client generates fully typed queries. Drizzle is right for performance-critical applications (Drizzle is faster than Prisma, smaller bundle) and Edge Runtime (Cloudflare Workers, Vercel Edge). TypeORM is legacy — new UK projects should use Prisma or Drizzle. ORM choice affects UK GDPR data access pattern safety, query type safety, and developer productivity. Here is a 2026 UK comparison.

Factor	Prisma	Drizzle	TypeORM
UK GDPR select (data minimisation)	✅ Prisma select — type-safe field selection	✅ Drizzle select — explicit columns	TypeORM select — verbose syntax
Type safety (query return types)	✅ Fully typed — Prisma Client types match schema	✅ Fully typed — inferred from schema	Partial — decorator-based types
Migration tooling	✅ prisma migrate — declarative schema diff	drizzle-kit push/generate — good	typeorm migrations — verbose
Performance (p99 query latency)	Good	✅ Fastest — minimal abstraction	Good
Edge Runtime (Vercel/Cloudflare)	Prisma Data Proxy — available	✅ Native — no proxy needed	Not edge-compatible
NHS DTAC / FCA — audit trail	✅ Prisma logging — all SQL logged	Custom logging required	Custom logging required
Raw SQL escape hatch	✅ prisma.$queryRaw — type-safe	✅ sql`` tagged template	TypeORM queryRunner
UK developer familiarity	✅ Most familiar — Prisma dominant	Growing rapidly	Declining
ClickMasters default	✅ All UK projects (NHS, FCA, GDS)	Edge + performance-critical	Legacy codebases only
