NestJS backend architecture for multi-tenant SaaS. Use for third-party API providers, Prisma or ZenStack setup, multitenancy, authentication, RBAC or policies, and repositories. Not for retries, events or dynamic modules — use resilient-nestjs-patterns.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NestJS Backend Architecture Patterns ## Apply - During a Stage B module task, keep controllers thin and put integration, tenancy, and authorization behind services. Stage A may scaffold only thin primitives. - Wrap each external SDK with an injected provider and export a service from its module; keep provider selection and credentials in configuration. - Resolve tenant context before database access and deny access when it is missing. Enforce resource permissions at the query or policy boundary, not only in controllers. - Keep authentication, authorization, persistence, and external integration in their respective modules. - Place shared Prisma, auth, and provider adapters under `shared/`; place domain controllers and DTOs in the domain's `feature-api` library. ## Load by task - For an external API adapter or provider switch, load [third-party integration](references/third-party-integration.md). - For tenant isolation and context propagation, load [multitenancy](references/multitenancy.md). - For Prisma or ZenStack setup and access policies, load [Prisma and ZenStack](references/prisma-zenstack.md). …

How to install
mdr add hive-academy/ptahcode/nestjs-backend-patterns@sha256:fa49ddc4ef48d9deThe line at the top of this page pins the label git:20261018.e46f918, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
