node-ts/ddd

This system is a Domain-Driven Design (DDD) library and example application focused on managing alarm states. It provides a modular architecture that separates core domain types from the main library to facilitate API and message transmission. The example application demonstrates this by handling alarm registration, triggering, and silencing via a CLI interface. The codebase also includes test infrastructure for reflection metadata and has been migrated to use pnpm as its package manager.

The ddd-example package now includes a complete domain-driven design example simulating a remote security monitoring system. The application allows users to register an alarm system, trigger alarms, and silence sirens via a CLI interface. The domain logic is separated from the CLI layer, with specific commands like SilenceAlarmSiren and events like AlarmSirenSilenced handling the core business rules for managing alarm states.

packages/ddd-example · medium confidence

The base DDD types (such as \AggregateRootProperties\, \EntityProperties\, and \Uuid\) have been extracted into a new \@node-ts/ddd-types\ package. This separation allows the domain contract types to be transmitted via APIs or messages without requiring the core DDD library and its peer dependencies. The \@node-ts/ddd\ package now depends on \@node-ts/ddd-types\ for these shared interfaces.

packages/ddd · high confidence

The placeholder test file (src/aggregate-root.spec.ts) and the corresponding abstract class (src/aggregate-root.ts) have been removed from the codebase. This cleanup eliminates unused code and associated test scaffolding that did not contribute to the application's functionality.

src · high confidence

Added a new test setup file (test/setup.ts) that imports 'reflect-metadata' to support reflection-based testing.

test · high confidence

The repository's package manager has been switched from Yarn to pnpm, evidenced by the removal of the yarn.lock file and the addition of pnpm-lock.yaml files across the workspace. The root package.json has been updated to use pnpm for all scripts, and dev dependencies such as Jest and ts-jest have been upgraded to version 28, with the Jest configuration updated to support pnpm's resolution and test patterns.
