@eac-arch/infrastructure-persistence

Angular infrastructure library with HTTP repository/query abstractions for data access.

Purpose

@eac-arch/infrastructure-persistence provides reusable base classes to implement repositories and query services over HTTP, keeping client code aligned with DDD/CQRS contracts from shared-kernel.

Main Capabilities

• ReadOnlyHttpRepository<TEntity, TDto, TQueryOptions> : Read operations (getAll, getById, exists) with DTO -> entity mapping.
• GenericHttpRepository<...> : Extends read-only base with create, upsert, updatePartial, and delete.
• HttpRepository<...> : Thin alias for common full CRUD use cases.
• HttpQueryService<TModel, TQueryOptions> : Base read-model query service with pagination, specification support, sort formatting, and sparse field selection.

Public API

export { ReadOnlyHttpRepository };
export { GenericHttpRepository };
export { HttpRepository };
export { HttpQueryService, type BaseQueryOptions };

Usage Pattern

1. Extend a repository base.
2. Implement transport delegates (doGetAll, doGetById, doCreate, etc.).
3. Implement DTO mapping (mapToEntity, extractId, optional rehydrate).
4. Reuse HttpQueryService for read-side pagination/filtering.
