almin/ddd-base

This system is a TypeScript-based domain modeling framework that provides foundational utilities for managing state and data persistence. It features a Repository pattern with event-driven updates for saving and deleting entities, alongside a Converter for serializing domain objects to and from JSON. Additionally, it includes a Copyable mixin for creating modified copies of objects without mutation, all supported by comprehensive test coverage.

A new \Copyable\ mixin has been added to \src/mixin/Copyable.ts\. This mixin provides two methods for creating modified copies of an object: \copy\, which accepts a partial object of new values, and \mapCopy\, which accepts a map of transformation functions to apply to existing properties. This allows users to generate new instances with updated or transformed state without mutating the original.

A new \Converter\ class and \createConverter\ factory function are added to handle the conversion between Entity/ValueObject instances and JSON formats. The \Converter\ supports nested conversions and provides methods like \toJSON\, \propsToJSON\, \JSONToProps\, and \fromJSON\. This allows users to easily serialize and deserialize domain objects to and from JSON structures.

src · high confidence

A new Repository abstraction is introduced, providing both a base \Repository\ interface and two concrete implementations: \NonNullableRepository\ (which always returns an initial entity) and \NullableRepository\ (which may return undefined). The implementation includes a \RepositoryCore\ that manages entity storage and exposes an \events\ property, allowing consumers to subscribe to \save\ and \delete\ changes via the \onChange\ method.

src/repository · high confidence

Added comprehensive test suites for the domain model and utility components, including Entity, ValueObject, RepositoryCore, NonNullableRepository, Serializer, Converter, and Copyable mixin. The new tests verify entity equality, value object comparison, repository save/find/delete/clear operations, serialization round-trips, and the copy/mapping behavior of the Copyable mixin.

The project's development dependencies have been updated to newer versions, including @types/node, @types/mocha, cross-env, husky, lerna, lint-staged, mocha, prettier, rimraf, ts-node, and typescript. Additionally, the package.json has been updated to specify the TypeScript type definitions file, changed the main entry point, added a clean script using rimraf, and reconfigured husky hooks directly in the package.json.
