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 change introduces a service layer to encapsulate the business logic
for each domain aggregate. This will make the code more modular,
testable, and easier to maintain.
The following services have been created:
- author
- bookmark
- category
- collection
- comment
- like
- tag
- translation
- user
The main Application struct has been updated to use these new services.
The integration test suite has also been updated to use the new
Application struct and services.
This is a work in progress. The next step is to fix the compilation
errors and then refactor the resolvers to use the new services.
This commit introduces a new application layer to the codebase, which decouples the GraphQL resolvers from the data layer. The resolvers now call application services, which in turn call the repositories. This change improves the separation of concerns and makes the code more testable and maintainable.
Additionally, this commit introduces dataloaders to solve the N+1 problem in the GraphQL resolvers. The dataloaders are used to batch and cache database queries, which significantly improves the performance of the API.
The following changes were made:
- Created application services for most of the domains.
- Refactored the GraphQL resolvers to use the new application services.
- Implemented dataloaders for the `Author` aggregate.
- Updated the `app.Application` struct to hold the application services instead of the repositories.
- Fixed a large number of compilation errors in the test files that arose from these changes.
There are still some compilation errors in the `internal/adapters/graphql/integration_test.go` file. These errors are due to the test files still trying to access the repositories directly from the `app.Application` struct. The remaining work is to update these tests to use the new application services.
This commit introduces a comprehensive enhancement of the application's analytics features, addressing performance, data modeling, and feature set.
The key changes include:
- **Performance Improvement:** The analytics repository now uses a database "UPSERT" operation to increment counters, reducing two separate database calls (read and write) into a single, more efficient operation.
- **New Metrics:** The `WorkStats` and `TranslationStats` models have been enriched with new, calculated metrics:
- `ReadingTime`: An estimation of the time required to read the work or translation.
- `Complexity`: A score representing the linguistic complexity of the text.
- `Sentiment`: A score indicating the emotional tone of the text.
- **Service Refactoring:** The analytics service has been refactored to support the new metrics. It now includes methods to calculate and update these scores, leveraging the existing linguistics package for text analysis.
- **GraphQL API Expansion:** The new analytics fields (`readingTime`, `complexity`, `sentiment`) have been exposed through the GraphQL API by updating the `WorkStats` and `TranslationStats` types in the schema.
- **Validation and Testing:**
- GraphQL input validation has been centralized and improved by moving from ad-hoc checks to a consistent validation pattern in the GraphQL layer.
- The test suite has been significantly improved with the addition of new tests for the analytics service and the data access layer, ensuring the correctness and robustness of the new features. This includes fixing several bugs that were discovered during the development process.
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.
