Atomic Repositories in Clean Architecture and TypeScript
The atomicity problem in the Repository Pattern occurs when multiple repositories execute their queries in one transaction, causing inconsistencies if any query fails. To achieve atomicity, we need to create a "transaction" that gets passed throughout our application calls. This is best demonstrated by using a Clean Architecture design. By creating transactions at the controller level and passing them down to every use case, we can ensure data consistency across operations that span multiple repositories. The implementation involves creating a TransactionManagerService that provides a transaction instance so repositories can participate in a shared transaction if provided or use the database driver directly if not. This method of handling transactions aligns well with Clean Architecture principles by separating concerns and keeping business logic decoupled from underlying database operations, ensuring reliability and consistency across dependent operations.
