backend-structure

To structure a multi-tenant NestJS backend module, enforce a standardized layout with module.ts, controller.ts, service.ts, repository.ts, and dto/ folders. This ensures consistency, domain boundary compliance, and tenant scoping via communityId across MongoDB persistence layers.

Creating a domain module in a Docker-first backend architecture requires module.ts, controller.ts, service.ts, repository.ts, and dto/ directories. You must also include optional guards/ or enums/ folders as needed to enforce domain-specific logic and environment-driven configuration.

Yes, this backend module structure supports multi-tenancy by enforcing communityId scoped queries across all MongoDB persistence layers. This ensures strict tenant data isolation and compliance within your NestJS domain boundaries.

You need to add guards and repositories to an existing NestJS domain module when extending it with new controllers or services. This maintains standardized module structure, ensures proper data access via MongoDB, and preserves domain boundary compliance.

The best way to enforce consistency across backend domain boundaries in NestJS is to apply a standardized module structure covering controllers, services, repositories, and DTOs. This enforces multi-tenancy via communityId and ensures Docker-friendly, environment-driven runtime patterns.
