Key changes include:
- **Architectural Refactoring (CQRS/DTOs):** Refactored the `work` and `translation` application services to use Data Transfer Objects (DTOs) for query responses. This separates the domain layer from the API layer, improving maintainability and performance.
- **Implemented Core Business Logic:** Implemented the `AnalyzeWork` command, which was previously a stub. This command now performs linguistic analysis on works and translations by calling the analytics service.
- **Dependency Injection Improvements:**
- Refactored the configuration loading in `internal/platform/config/config.go` to use a local `viper` instance, removing the reliance on a global singleton.
- Injected the `analytics.Service` into the `work.Service` to support the `AnalyzeWork` command.
- **Comprehensive Documentation:**
- Created a new root `README.md` with a project overview, setup instructions, and architectural principles.
- Added detailed `README.md` files to key packages (`api`, `analytics`, `auth`, `work`, `db`) to document their purpose and usage.
- **Improved Test Coverage:**
- Added new unit tests for the refactored `work` and `translation` query handlers.
- Added a new test suite for the `translation` queries, which were previously untested.
- Added tests for the new `AnalyzeWork` command.
- Fixed numerous compilation errors in the test suites caused by the refactoring.
This commit addresses several high-priority tasks from the TASKS.md file, including:
- **Fix Background Job Panic:** Replaced `log.Fatalf` with `log.Printf` in the `asynq` server to prevent crashes.
- **Refactor API Server Setup:** Consolidated the GraphQL Playground and Prometheus metrics endpoints into the main API server.
- **Implement `DeleteUser` Mutation:** Implemented the `DeleteUser` resolver.
- **Implement `CreateContribution` Mutation:** Implemented the `CreateContribution` resolver and its required application service.
Additionally, this commit includes a major refactoring of the configuration management system to fix a broken build. The global `config.Cfg` variable has been removed and replaced with a dependency injection approach, where the configuration object is passed to all components that require it. This change has been applied across the entire codebase, including the test suite, to ensure a stable and testable application.
The goal of this refactoring is to eliminate the global configuration singleton (`config.Cfg`) and replace it with explicit dependency injection of a `Config` struct.
This commit includes the following partial changes:
- The `Config` struct in `internal/platform/config/config.go` has been updated with all necessary fields.
- Several platform packages (`db`, `cache`, `auth`, `http`, `jobs/sync`) have been modified to accept the `*config.Config` struct.
- The API server entry point (`cmd/api/main.go`) has been updated to load and provide the configuration.
- A new worker entry point (`cmd/worker/main.go`) has been created to house the background job runner, as per the architecture defined in `refactor.md`.
NOTE: The build is currently broken as this refactoring is incomplete. This commit is for saving progress as requested.
This commit refactors the API server startup logic in `cmd/api/main.go` to simplify the application's architecture.
Key changes:
- Consolidates the three separate HTTP servers (GraphQL API, GraphQL Playground, and Prometheus metrics) into a single `http.Server` instance.
- Uses a single `http.ServeMux` to route requests to the appropriate handlers on distinct paths (`/query`, `/playground`, `/metrics`).
- Removes the now-redundant `PlaygroundPort` from the application's configuration.
This change simplifies the server startup and shutdown logic, reduces resource usage, and makes the application's entry point cleaner and easier to maintain.
