This commit introduces a comprehensive set of foundational improvements to make the API more robust, secure, and observable.
The following features have been implemented:
- **Observability Stack:** A new `internal/observability` package has been added, providing structured logging with `zerolog`, Prometheus metrics, and OpenTelemetry tracing. This stack is fully integrated into the application's request pipeline.
- **Centralized Authorization:** A new `internal/app/authz` service has been created to centralize authorization logic. This service is now used by the `user`, `work`, and `comment` services to protect all Create, Update, and Delete operations.
- **Standardized Input Validation:** The previous ad-hoc validation has been replaced with a more robust, struct-tag-based system using the `go-playground/validator` library. This has been applied to all GraphQL input models.
- **Structured Error Handling:** A new set of custom error types has been introduced in the `internal/domain` package. A custom `gqlgen` error presenter has been implemented to map these domain errors to structured GraphQL error responses with specific error codes.
- **`updateUser` Endpoint:** The `updateUser` mutation has been fully implemented as a proof of concept for the new patterns, including support for partial updates and comprehensive authorization checks.
- **Test Refactoring:** The test suite has been significantly improved by decoupling mock repositories from the shared `testutil` package, resolving circular dependency issues and making the tests more maintainable.
This commit isolates the `Work` aggregate into its own package at `internal/domain/work`, following the first step of the refactoring plan in `refactor.md`.
- The `Work` struct, related types, and the `WorkRepository` interface have been moved to the new package.
- A circular dependency between `domain` and `work` was resolved by moving the `AnalyticsRepository` to the `app` layer.
- All references to the moved types have been updated across the entire codebase to fix compilation errors.
- Test files, including mocks and integration tests, have been updated to reflect the new structure.
This commit refactors the GraphQL test suite to resolve persistent build failures and establish a stable, mock-based unit testing environment.
The key changes include:
- Consolidating all GraphQL test helper functions into a single, canonical file (`internal/adapters/graphql/graphql_test_utils_test.go`).
- Removing duplicated test helper code from `integration_test.go` and other test files.
- Creating a new, dedicated unit test file for the `like` and `unlike` mutations (`internal/adapters/graphql/like_resolvers_unit_test.go`) using a mock-based approach.
- Introducing mock services (`MockLikeService`, `MockAnalyticsService`) and updating mock repositories (`MockLikeRepository`, `MockWorkRepository`) in the `internal/testutil` package to support `testify/mock`.
- Adding a `ContextWithUserID` helper function to `internal/platform/auth/middleware.go` to facilitate testing of authenticated resolvers.
These changes resolve the `redeclared in this block` and package collision errors, resulting in a clean and passing test suite. This provides a solid foundation for future Test-Driven Development.
This commit completes the Domain-Driven Design (DDD) refactoring, bringing the codebase into a stable, compilable, and fully tested state.
Key changes include:
- Refactored the `localization` service to use a Commands/Queries pattern, aligning it with the new architecture.
- Implemented the missing `GetAuthorBiography` query in the `localization` service to simplify resolver logic.
- Corrected GORM entity definitions for polymorphic relationships, changing `[]Translation` to `[]*Translation` to enable proper preloading of translations.
- Standardized the `TranslatableType` value to use the database table name (e.g., "works") instead of the model name ("Work") to ensure consistent data creation and retrieval.
- Updated GraphQL resolvers to exclusively use application services instead of direct repository access, fixing numerous build errors.
- Repaired all failing unit and integration tests by updating mock objects and correcting test data setup to reflect the architectural changes.
These changes resolve all outstanding build errors and test failures, leaving the application in a healthy and maintainable state.
This commit addresses a broken build state caused by a mid-stream architectural refactoring. The changes align the existing code with the new Domain-Driven Design (DDD-lite) structure outlined in `refactor.md`.
Key changes include:
- Defined missing domain interfaces for `Auth`, `Localization`, and `Search`.
- Refactored application services to use a `Commands` and `Queries` pattern.
- Updated GraphQL resolvers to call application services instead of accessing repositories directly.
- Fixed dependency injection in `cmd/api/main.go` by removing the non-existent `ApplicationBuilder` and manually instantiating services.
- Corrected numerous test files (`integration`, `unit`, and `repository` tests) to reflect the new architecture, including fixing mock objects and test suite setups.
- Added missing database migrations for test schemas to resolve "no such table" errors.
This effort successfully gets the application to a compilable state and passes a significant portion of the test suite, laying the groundwork for further development and fixing the remaining test failures.
This commit includes the following changes:
- Refactored all data repositories in `internal/data/sql/` to use a consistent `sql` package and to align with the new `domain` models.
- Fixed the GraphQL structure by moving the server creation logic from `internal/app` to `cmd/api`, which resolved an import cycle.
- Corrected numerous incorrect import paths for packages like `graph`, `linguistics`, `syncjob`, and the legacy `models` package.
- Resolved several package and function redeclaration errors.
- Removed legacy migration code.
