Prisma vs Drizzle for NHS HealthTech?

Prisma for NHS HealthTech: single-tenant applications, no RLS needed, non-Edge/Lambda. Drizzle for NHS HealthTech: PostgreSQL RLS required (multi-tenant NHS SaaS), Edge/Lambda deployment (zero runtime critical), complex FHIR JSONB queries. ClickMasters default: Prisma for single-tenant NHS, Drizzle for multi-tenant NHS SaaS with RLS.

TypeORM with TypeScript strict mode?

TypeORM with strict mode has issues: Partial entity types, decorator metadata requiring experimental decorators, less precise query builder return types. ClickMasters recommendation: do not start new UK project with TypeORM in 2026. Migrate existing TypeORM to Prisma or Drizzle when opportunity arises (major version upgrade, architecture change).

Direct Answer

Prisma is ClickMasters default for most UK TypeScript projects: excellent TypeScript types, Prisma Studio for data inspection, and the most intuitive query API. Drizzle is right when performance and bundle size are critical (Prisma query engine adds 40MB -- Drizzle is zero runtime). TypeORM is legacy for new UK builds. ORM choice affects NHS patient data query correctness, FCA financial record accuracy, and UK GDPR right-to-erasure implementation.

Factor	Prisma	Drizzle	TypeORM
TypeScript type safety	BEST -- generated types from schema	BEST -- types inferred from schema	Good -- decorators, some gaps
NHS patient data safety	BEST -- generated types prevent wrong field access	BEST -- compile-time query validation	Good -- requires careful typing
UK GDPR erasure	Prisma delete + cascade options	Drizzle SQL delete + transactions	TypeORM cascade support
PostgreSQL RLS	Via SQL extensions -- workaround required	Direct SQL -- RLS compatible	Via raw SQL -- workaround
Bundle size (Edge/Lambda)	40MB query engine -- too large for Edge	BEST -- zero runtime, SQL compile time	15MB -- smaller than Prisma
Prisma Studio (dev tool)	BEST -- visual data browser in development	No equivalent	No equivalent
Migration management	Prisma Migrate -- excellent	Drizzle Kit -- good	TypeORM migration -- adequate
NHS FHIR JSONB queries	Prisma json filter -- limited deep queries	Raw SQL fallback -- flexible	queryBuilder -- flexible
ClickMasters default	All UK TypeScript projects	Edge functions, Lambda, RLS multi-tenant	Legacy projects only
