Why is TypeORM declining for UK projects?

TypeORM has accumulated significant technical debt — decorator-based patterns that don't play well with TypeScript strict mode, inconsistent behaviour across database adapters, and a slower response to TypeScript ecosystem improvements. Both Prisma and Drizzle provide better type safety, better developer experience, and better community support for new UK projects in 2025. ClickMasters migrated away from TypeORM in 2023.

Does Prisma work with PostgreSQL Row-Level Security for UK GDPR multi-tenant apps?

Prisma supports RLS via the $extends mechanism and middleware. For UK GDPR multi-tenant isolation: you can set the PostgreSQL session variable (app.current_tenant) before each query via Prisma middleware, and RLS policies filter automatically. This is the most secure UK GDPR multi-tenant pattern — data isolation enforced at the database level, not the application level.

Direct Answer

Prisma is the right default for most UK TypeScript projects: excellent developer experience, type-safe query builder, automatic migrations, and the UK's largest TypeScript ORM community. Drizzle is better for performance-critical applications where Prisma's abstraction adds latency. TypeORM is declining — avoid for new UK projects. ClickMasters defaults to Prisma on all TypeScript projects. ORM choice for TypeScript significantly affects developer productivity, type safety, and long-term maintainability. Here is an honest UK market comparison including UK GDPR data model implications.

Factor	Prisma	TypeORM	Drizzle
Type safety	✅ Excellent — generated client types	Partial — decorators, some any types	✅ Excellent — SQL-like type inference
Developer experience	✅ Best-in-class	Verbose — lots of boilerplate	Good — concise, SQL-close
Migration management	✅ Prisma Migrate — excellent	TypeORM migrations — verbose	Drizzle Kit — good, improving
UK GDPR schema documentation	✅ schema.prisma is self-documenting	Schema spread across entities	schema.ts is readable
Right to erasure implementation	✅ Cascade delete in schema	Manual cascade — error-prone	SQL CASCADE — explicit
Performance	Good — slight abstraction overhead	Good	✅ Best — thin abstraction
Raw SQL escape hatch	Prisma.$queryRaw	Repository.query()	sql template literal
PostgreSQL RLS (multi-tenant GDPR)	Via raw SQL extension	Via raw SQL	Via sql template — natural
UK developer community	✅ Largest	Declining	Growing
ClickMasters default	✅ All TypeScript projects	Not recommended	High-throughput specific cases
