Is Turborepo or Nx right for a UK HealthTech monorepo?

Turborepo vs Nx for UK HealthTech monorepo: Turborepo for TypeScript-only (Next.js + Node.js -- lightweight, minimal configuration, excellent for teams < 20 engineers), Nx for mixed technology (TypeScript + Python ML + AWS CDK -- Nx handles multi-language, generators for NHS boilerplate). ClickMasters HealthTech default: Turborepo for NHS HealthTech startups (Next.js frontend + Node.js FHIR API + shared types -- lightweight, fast CI), Nx for NHS HealthTech enterprises (multiple services, Python ML pipeline, CDK infrastructure -- Nx affected commands prevent unnecessary rebuilds). Both: shared packages for FHIR R4 UK Core types, NHS Login OAuth 2.0 utilities, DCB0129 audit logging.

Does monorepo satisfy NHS DTAC IEC 62304 traceability?

IEC 62304 traceability in monorepo: IEC 62304 requires traceability from requirements to design to implementation to tests. Monorepo advantage: (1) a single commit can cover requirement (in JIRA via commit message), implementation (code changes across frontend and backend), and test (test files in same commit) -- IEC 62304 traceability in one GitHub commit, (2) PR review covers all layers simultaneously (clinical safety engineer reviews frontend + backend + tests in one PR), (3) GitHub Actions CI evidence (single run covers all services -- DTAC Domain 3 evidence for entire system). ClickMasters IEC 62304 monorepo pattern: PR description template includes requirement reference, hazard log reference, and test coverage -- DTAC Domain 3 evidence pack generated per PR.

Direct Answer

Monorepo (Turborepo or Nx) is ClickMasters default for UK regulated TypeScript full-stack projects: shared types between frontend and backend (NHS FHIR R4 types used in both React and Node.js), shared UK GDPR utilities, unified CI/CD. Polyrepo is right for large organisations with independent team autonomy (NHS Digital -- separate repos per NHS API). Monorepo is wrong for diverse technology stacks (Python ML + Node.js API + React -- Nx handles this, but adds complexity). Monorepo vs polyrepo affects NHS DTAC evidence generation, FCA PS21/3 change management audit trail, and UK GDPR data model consistency across services.

Factor	Monorepo (Turborepo/Nx)	Polyrepo
Shared TypeScript types	BEST -- FHIR R4 types shared across all services	Separate type packages -- version drift risk
NHS DTAC evidence (single audit trail)	BEST -- single GitHub repo audit log for all services	Multiple repo audit logs -- harder to aggregate
FCA PS21/3 deployment audit	BEST -- unified deployment history across all IBS services	Per-repo deployment history -- manual aggregation
UK GDPR shared utilities	BEST -- shared consent, erasure, audit middleware	Duplicate or drifting GDPR utilities per repo
Team autonomy	Shared context -- teams see each other's code	BEST -- complete team isolation
Large scale (100+ engineers)	Can become slow -- Nx affected commands help	BEST -- each team independently scales
Dependency management	Unified -- one package.json (or workspace)	Per-repo -- each team controls their dependencies
NHS HSCN runner caching	BEST -- shared Turborepo cache across all services	Per-repo cache -- no cross-service cache benefit
ClickMasters default	All TypeScript full-stack UK regulated projects	Large orgs (100+ engineers), diverse tech stacks
