@eac-arch/shared-kernel

Shared kernel library with domain, application, exception, and utility contracts used across EAC Angular packages.

Purpose

@eac-arch/shared-kernel defines stable cross-layer primitives so infrastructure and feature packages can share a common language aligned with server-side architecture.

Modules

• domain : Entity, AggregateRoot, ValueObject, domain events, specification pattern (including composable query specifications).
• application : request/result messaging, command/query contracts, repository interfaces, query service contracts, paged list helpers, data shaping helpers.
• exceptions : BaseException and typed domain/application exception classes.
• utils : sort field parsing/formatting, patch operation builders, age/date helpers.

Representative API

export * from '@eac-arch/shared-kernel';

// Examples:
createPagedList(...)
formatSortFields(...)
buildReplacePatches(...)
new ValidationException([...])

Key Design Notes

• Emphasizes interfaces/contracts over concrete implementations.
• Encodes CQRS concepts (Command, Query, IQueryService).
• Encodes DDD concepts (Entity, AggregateRoot, ValueObject, Specification).
• Patch and sorting utilities are transport-agnostic and reused by persistence/http libraries.

Dependencies

• Angular peer baseline (common/core)
• tslib

No dependency on other @eac-arch/* libraries; this is the foundational package.
