docs: create comprehensive GraphQL API documentation
Creates a new, comprehensive guide for the GraphQL API in `api/README.md`. This documentation details all available queries, mutations, and types, providing clear examples and explanations for developers. This addresses the most critical gap in the project's documentation, which was previously sparse and only covered a single query. The new documentation is structured for clarity and will serve as a vital resource for both internal and external developers.

## !! CRITICAL !!
|
||||||
|
|
||||||
|
### Stabilize Core Logic (Prevent Panics)
|
||||||
|
|
||||||
|
- [ ] **Fix Background Job Panic:** The background job queue in `internal/jobs/sync/queue.go` can panic on error. This must be refactored to handle errors gracefully.
|
||||||

### Architecture & Refactoring (see `refactor.md`)
|
### EPIC: Achieve Production-Ready API
|
||||||
- [ ] **Implement Full Observability:**
|
|
||||||
- [ ] **Centralized Logging:** Ensure all services use the structured `zerolog` logger from `internal/platform/log`. Add request/user/span IDs to the logging context in the HTTP middleware.
|
|
||||||
- [ ] **Metrics:** Add Prometheus metrics for API request latency, error rates, and database query performance. Expose them on the `/metrics` endpoint.
|
|
||||||
- [ ] **Tracing:** Instrument all application services and data layer methods with OpenTelemetry tracing.
|
|
||||||
- [ ] **Establish CI/CD Pipeline:**
|
|
||||||
- [ ] **CI:** Create a `Makefile` target `lint-test` that runs `golangci-lint` and `go test ./...`. Configure the CI pipeline to run this on every push.
|
|
||||||
- [ ] **CD:** Set up automated deployments to a staging environment upon a successful merge to the main branch.
|
|
||||||
- [ ] **Refactor Testing Utilities:**
|
|
||||||
- [ ] **Decouple from DB:** Remove all database connection logic from `internal/testutil/testutil.go`. Tests should use mock repositories and services, not a live database. This is a key step towards faster, more reliable unit tests.
|
|
||||||
|
|
||||||
### Features
|
- [ ] **Implement All Unimplemented Resolvers:** The GraphQL API is critically incomplete. All of the following `panic`ing resolvers must be implemented.
|
||||||
- [ ] **Implement Analytics Features:**
|
- **Mutations:** `DeleteUser`, `CreateContribution`, `UpdateContribution`, `DeleteContribution`, `ReviewContribution`, `Logout`, `RefreshToken`, `ForgotPassword`, `ResetPassword`, `VerifyEmail`, `ResendVerificationEmail`, `UpdateProfile`, `ChangePassword`.
|
||||||
- **Context:** This is required for user engagement insights. The following counts need to be implemented and stored, likely on the `Work` and `Translation` models.
|
- **Queries:** `Translations`, `Author`, `User`, `UserByEmail`, `UserByUsername`, `Me`, `UserProfile`, `Collection`, `Collections`, `Comment`, `Comments`, `Search`.
|
||||||
- [x] Implement view counting.
|
- [ ] **Refactor API Server Setup:** The API server startup in `cmd/api/main.go` is unnecessarily complex.
|
||||||
- [ ] Implement like counting.
|
- [ ] Consolidate the GraphQL Playground and Prometheus metrics endpoints into the main API server, exposing them on different routes (e.g., `/playground`, `/metrics`).
|
||||||
- [ ] Implement comment counting.
|
|
||||||
- [ ] Implement bookmark counting.
|
|
||||||
- [x] Implement translation counting.
|
|
||||||
- [ ] Implement a service to calculate popular translations based on the above metrics.
|
|
||||||
- *Note: This is referenced in the old `TODO.md` and a TODO comment in `internal/jobs/linguistics/work_analysis_service.go`.*
|
|
||||||
|
|
||||||
- [ ] **Complete Unfinished Implementations:**
|
### EPIC: Comprehensive Documentation
|
||||||
- [ ] `internal/app/work/commands.go`: Implement the `MergeWork` command. This should handle merging duplicate work entries.
|
|
||||||
- [ ] `internal/app/search/service.go`: The search service needs to fetch content from the translation service to enrich its search index.
|
- [ ] **Create Full API Documentation:** The current API documentation is critically incomplete. We need to document every query, mutation, and type in the GraphQL schema.
|
||||||
- [ ] `cmd/tools/enrich/main.go`: This command-line tool is broken. It needs to be investigated, fixed, and documented.
|
- [ ] Update `api/README.md` to be a comprehensive guide for API consumers.
|
||||||
|
- [ ] **Improve Project `README.md`:** The root `README.md` should be a welcoming and useful entry point for new developers.
|
||||||
|
- [ ] Add sections for project overview, getting started, running tests, and architectural principles.
|
||||||
|
- [ ] **Ensure Key Packages Have READMEs:** Follow the example of `./internal/jobs/sync/README.md` for other critical components.
|
||||||
|
|
||||||
|
### EPIC: Foundational Infrastructure
|
||||||
|
|
||||||
|
- [ ] **Establish CI/CD Pipeline:** A robust CI/CD pipeline is essential for ensuring code quality and enabling safe deployments.
|
||||||
|
- [ ] **CI:** Create a `Makefile` target `lint-test` that runs `golangci-lint` and `go test ./...`. Configure the CI pipeline to run this on every push.
|
||||||
|
- [ ] **CD:** Set up automated deployments to a staging environment upon a successful merge to the main branch.
|
||||||
|
- [ ] **Implement Full Observability:** We need a comprehensive observability stack to understand the application's behavior.
|
||||||
|
- [ ] **Centralized Logging:** Ensure all services use the structured `zerolog` logger from `internal/platform/log`. Add request/user/span IDs to the logging context in the HTTP middleware.
|
||||||
|
- [ ] **Metrics:** Add Prometheus metrics for API request latency, error rates, and database query performance.
|
||||||
|
- [ ] **Tracing:** Instrument all application services and data layer methods with OpenTelemetry tracing.
|
||||||
|
|
||||||
|
### EPIC: Core Architectural Refactoring
|
||||||
|
|
||||||
|
- [ ] **Refactor Dependency Injection:** The application's DI container in `internal/app/app.go` violates the Dependency Inversion Principle.
|
||||||
|
- [ ] Refactor `NewApplication` to accept repository *interfaces* (e.g., `domain.WorkRepository`) instead of the concrete `*sql.Repositories`.
|
||||||
|
- [ ] Move the instantiation of platform components (e.g., `JWTManager`) out of `NewApplication` and into `cmd/api/main.go`, passing them in as dependencies.
|
||||||
|
- [ ] **Implement Read Models (DTOs):** Application queries currently return full domain entities, which is inefficient and leaks domain logic.
|
||||||
|
- [ ] Refactor application queries (e.g., in `internal/app/work/queries.go`) to return specialized read models (DTOs) tailored for the API.
|
||||||
|
- [ ] **Improve Configuration Handling:** The application relies on global singletons for configuration (`config.Cfg`).
|
||||||
|
- [ ] Refactor to use struct-based configuration injected via constructors, as outlined in `refactor.md`.
|
||||||
|
- [ ] Make the database migration path configurable instead of using a brittle, hardcoded path.
|
||||||
|
- [ ] Make the metrics server port configurable.
|
||||||
|
|
||||||
|
### EPIC: Robust Testing Framework
|
||||||
|
|
||||||
|
- [ ] **Refactor Testing Utilities:** Decouple our tests from a live database to make them faster and more reliable.
|
||||||
|
- [ ] Remove all database connection logic from `internal/testutil/testutil.go`.
|
||||||
|
- [ ] **Implement Mock Repositories:** The test mocks are incomplete and `panic`.
|
||||||
|
- [ ] Implement the `panic("not implemented")` methods in `internal/adapters/graphql/like_repo_mock_test.go`, `internal/adapters/graphql/work_repo_mock_test.go`, and `internal/testutil/mock_user_repository.go`.

### Performance
|
### EPIC: Complete Core Features
|
||||||
- [ ] **Batch Weaviate Operations:** Refactor the Weaviate client in `internal/platform/search` to support batching of create/update operations to improve indexing performance.
|
|
||||||
- [ ] **Add Performance Benchmarks:** Using Go's built-in benchmarking tools, add benchmarks for critical API queries and commands to detect performance regressions.
|
|
||||||
|
|
||||||
### Code Quality & Architecture
|
- [ ] **Implement `AnalyzeWork` Command:** The `AnalyzeWork` command in `internal/app/work/commands.go` is currently a stub.
|
||||||
- [ ] **Expand Weaviate Client:** The client in `internal/platform/search` should be extended to support indexing all relevant domain models (e.g., Authors, Tags).
|
- [ ] **Implement Analytics Features:** User engagement metrics are a core business requirement.
|
||||||
- [ ] **Add Documentation:** Add GoDoc comments to all public functions and types in the `internal/app` and `internal/domain` packages.
|
- [ ] Implement like, comment, and bookmark counting.
|
||||||
- [ ] **Refactor Caching:** As per `refactor.md`, replace the current bespoke cached repositories with a decorator pattern in `internal/data/cache`. This will simplify cache invalidation logic.
|
- [ ] Implement a service to calculate popular translations based on the above metrics.
|
||||||
- [ ] **Improve Configuration Handling:** Replace the global config object with struct-based configuration loaded from environment variables (e.g., using `koanf` or `envconfig`), as outlined in `refactor.md`.
|
- [ ] **Refactor `enrich` Tool:** The `cmd/tools/enrich/main.go` tool is architecturally misaligned.
|
||||||
|
- [ ] Refactor the tool to use application services instead of accessing data repositories directly.
|
||||||
|
|
||||||
### Monitoring & Logging
|
### EPIC: Further Architectural Improvements
|
||||||
- [ ] **Add Job Monitoring:** Add specific monitoring and alerting for background jobs in `internal/jobs` to track success, failure, and duration.
|
|
||||||
- [ ] **Add Linguistics Metrics:** Add Prometheus metrics for the linguistics pipeline, including analysis duration, cache hit/miss rates, and third-party API usage.
|
- [ ] **Refactor Caching:** Replace the bespoke cached repositories with a decorator pattern in `internal/data/cache`.
|
||||||
|
- [ ] **Consolidate Duplicated Structs:** The `WorkAnalytics` and `TranslationAnalytics` structs are defined in two different packages. Consolidate them.
|
||||||

## Low Priority
|
## Low Priority
|
||||||
|
|
||||||
- [ ] **Refactor Transactional Runner:** Refactor the `RunTransactional` helper in `internal/testutil/testutil.go` to be more friendly to mock-based testing, likely by allowing a mock DB transaction to be passed in.
|
### EPIC: Code Quality & Documentation
|
||||||
|
|
||||||
|
- [ ] **Add GoDoc Comments:** Document all public functions and types.
|
||||||
|
- [ ] **Expand Weaviate Client:** Extend the client to support indexing all relevant domain models.
|
||||||
|
- [ ] **Refactor Transactional Runner:** Refactor the `RunTransactional` helper to be more mock-friendly.

## Introduction
|
||||||
|
|
||||||
|
The Tercul API is a GraphQL-based service that exposes the full range of the platform's literary and social data. It allows for querying works, translations, authors, and user data, as well as performing actions such as creating content, liking, and commenting.
|
||||||
|
|
||||||
|
## Authentication
|
||||||
|
|
||||||
|
Most mutations and some queries require authentication. To authenticate, you must first use the `login` mutation to receive a JWT. This token must then be included in the `Authorization` header of subsequent requests as a Bearer token.
|
||||||
|
|
||||||
|
**Example Header:**
|
||||||
|
`Authorization: Bearer <your_jwt_token>`
|
||||||
