From 260460149ae25911f6268988df6cadd4872f4d73 Mon Sep 17 00:00:00 2001 From: StefanMoCoAt Date: Mon, 28 Jul 2025 22:43:28 +0200 Subject: [PATCH] refactor(core): Unify components and adopt standard tooling This commit performs several key refactorings within the `core`-module to improve consistency, stability, and adhere to industry best practices. 1. **Unify `Result` Type:** Removed the specialized `Result` class from `core-utils`. The entire system will now exclusively use the more flexible and type-safe `Result` from `core-domain`. This allows for explicit, non-exception-based error handling for business logic. 2. **Adopt Flyway for Database Migrations:** Replaced the custom `DatabaseMigrator.kt` implementation with the industry-standard tool Flyway. The `DatabaseFactory` now triggers Flyway migrations on application startup. This provides more robust, transactional, and feature-rich schema management. 3. **Cleanup and Housekeeping:** - Removed obsolete test files related to the old migrator. - Ensured all components align with the new unified patterns. BREAKING CHANGE: The `at.mocode.core.utils.error.Result` class has been removed. All modules must be updated to use the `at.mocode.core.domain.error.Result` type. The custom migrator is no longer available.
