+## Project Overview
+
+**kurious** (`git.loyso.art/frx/kurious`) is a course/education platform that
+aggregates and serves educational course listings. It scrapes/syncs course data
+from an external source (sravni.ru) via a rate-limited HTTP client, stores it
+locally, and exposes it through a server-rendered web UI with filtering,
+pagination, and statistics.
+
+The project is written in Go and follows a hexagonal (ports & adapters)
+architecture with a CQRS-flavored application layer.
+
+## Tech Stack
+
+- **Language:** Go 1.26 (toolchain `go1.26.4`; see `go.mod`)
+- **HTTP routing:** `github.com/gorilla/mux`
+- **HTTP client:** `github.com/go-resty/resty/v2` (sravni.ru scraper)
+- **Database:** SQLite via `modernc.org/sqlite` (pure-Go, CGO disabled).
+  YDB was historically supported but is **no longer supported**
+  (`service.NewApplication` returns an error for the YDB engine).
+- **DB access:** `github.com/jmoiron/sqlx` (named queries)
+- **Templating:** `github.com/a-h/templ` (`.templ` files compile to Go)
+- **Observability:** OpenTelemetry (`go.opentelemetry.io/otel`) — traces and
+  metrics with stdout / OTLP (HTTP & gRPC) exporters
+- **Background jobs:** `github.com/robfig/cron/v3`
+- **Logging:** standard `log/slog` (text or JSON, configurable)
+- **Rate limiting:** `golang.org/x/time/rate`
+- **Testing:** `github.com/stretchr/testify` (assert, require, mock)
+- **Mocking:** `github.com/vektra/mockery/v2` (config in `.mockery.yaml`)
+- **Linting:** `golangci-lint` v1.55.2
+- **Build/task runner:** [Taskfile](https://taskfile.dev) (`Taskfile.yml`)
+- **Build flags:** ldflags inject `version`, `commit`, `buildTime`
+  (see `kurious.go`)
+
+## Architecture
+
+The codebase implements a **hexagonal architecture** (ports & adapters) with a
+CQRS-style separation between commands (writes) and queries (reads).
+
+```

+```
+
+- **`domain/`** — pure business entities (`Course`, `Organization`,
+  `LearningCategory`) and the **repository interfaces** (ports) that the
+  application depends on: `CourseRepository`, `OrganizationRepository`,
+  `LearningCategoryRepository`. No I/O or framework code lives here.
+- **`app/`** — the application layer. `app.Application` aggregates a
+  `Commands` struct and a `Queries` struct. Handlers in `app/command/` perform
+  writes; handlers in `app/query/` perform reads. Each handler implements a
+  generic `decorator.CommandHandler[T]` or `decorator.QueryHandler[Q, U]`
+  interface and is wrapped with logging decorators at construction time.
+- **`adapters/`** — concrete implementations of the domain repository ports.
+  `sqlite_course_repository.go`, `sqlite_organization_repository.go`, etc.
+  translate between domain types and SQL rows. `memory_mapper.go` is an
+  in-memory mapper translating external dictionary IDs to human-readable names.
+- **`ports/`** — delivery mechanisms. `ports/http/` is the HTTP server (gorilla/mux
+  + templ templates); `ports/background/` runs scheduled cron jobs (e.g.
+  `SyncSravniHandler`).
+- **`service/`** — the **composition root**. `service.NewApplication` selects
+  the DB engine, constructs the SQLite connection, builds the adapters, and
+  wires everything into an `app.Application`. This is what binaries call.
+
+Data flows: an HTTP request enters `ports/http`, calls a handler on
+`service.Application` (which delegates to `app/command` or `app/query`), which
+calls a `domain` repository interface implemented by an `adapters/*` repository.

+
+## Build, Test, and Lint Commands
+
+All operations are driven by **Taskfile** (`task <name>`). The toolchain is
+installed into a local `bin/` (`GOBIN={{.USER_WORKING_DIR}}/bin`) and
+`CGO_ENABLED=0` is enforced.
+
+| Command                  | What it does                                                       |
+|--------------------------|--------------------------------------------------------------------|
+| `task install_tools`     | Install `golangci-lint`, `templ`, `mockery` into `bin/`            |
+| `task generate`          | Run `templ generate` (compiles `.templ` → `_templ.go`)             |
+| `task mocks`             | Run `go generate ./internal/...` (regenerate mockery mocks)        |
+| `task check`             | Run `golangci-lint run ./...` (depends on `generate`)              |
+| `task test`              | Run `go test ./internal/...` (depends on `generate`)               |
+| `task build_web`         | Build `bin/kuriousweb` (depends on `check` + `test`)               |
+| `task build_background`  | Build `bin/kuriousbg` (depends on `check` + `test`)                |
+| `task build_dev_cli`     | Build `bin/sravnicli` (depends on `check` + `test`)                |
+| `task build`             | Build all three binaries                                           |
+| `task run`               | Build then run `bin/kuriousweb`                                    |
+
+Typical workflow before committing: `task check && task test`.
+
+### Running the binaries
+
+Binaries read a JSON config file path as their first argument, defaulting to
+`config.json` (note: `*.json` is gitignored, so configs are local). Example
+fields: `log`, `sqlite`, `http.listen_addr`, `db_engine`, `tracing`.
+
+```bash
+./bin/kuriousweb path/to/config.json
+```
+
+## Code Conventions
+
+### Decorators / handler pattern
+
+Command and query handlers implement generic interfaces and are wrapped with
+logging decorators at construction time. When adding a new use case:
+
+1. Define the command/query struct and a `*Handler` type alias of
+   `decorator.CommandHandler[T]` / `decorator.QueryHandler[Q, U]` in
+   `app/command/` or `app/query/`.
+2. Implement a private `*Handler` struct holding its repository dependencies.
+3. Expose a `New*Handler(deps..., log *slog.Logger)` constructor that returns
+   the decorated handler (`decorator.ApplyCommandDecorators` /
+   `decorator.AddQueryDecorators`).
+4. Register the new handler on `app.Commands` / `app.Queries` in
+   `app/app.go` and wire it in `service/service.go`.
+
+### Mock generation (mockery)
+
+- Interfaces marked with `//go:generate mockery ...` directives (see
+  `domain/repository.go`, `common/client/sravni/client.go`) are mocked into
+  sibling `mocks/` packages (`keeptree: True`, `with-expecter: true`).
+- Regenerate with `task mocks` (runs `go generate ./internal/...`).
+- Mocks are committed to the repo.
+
+### Templating (templ)
+
+- HTML is authored as `.templ` files under
+  `internal/kurious/ports/http/bootstrap/`.
+- `task generate` compiles them to `*_templ.go` (committed). Run it whenever a
+  `.templ` file changes; `task check` and `task test` both depend on it.
+
+### Database / migrations
+
+- SQLite migrations live in `migrations/sqlite/*.sql` and are embedded via
+  `go:embed`. The migrator (`migrations/sqlite/migrator.go`) applies them in
+  order inside a transaction.
+- Repository adapters use `sqlx` named queries; domain ↔ row translation is
+  centralized via `AsDomain()` methods.
+
+### Logging & observability
+
+- Use `log/slog` with structured attributes. Request-scoped fields (e.g.
+  `request_id`) are propagated through `context` via `internal/common/xcontext`.
+- HTTP handlers wrap requests in trace spans and record metrics
+  (request duration histogram). Database adapters emit spans tagged with
+  `db.*` attributes.
+
+### Error handling
+
+- Domain/repository errors use sentinels from `internal/common/errors`
+  (`ErrNotFound`, `ErrNotImplemented`) and `*ValidationError` (mapped to HTTP
+  400/404 in `ports/http/server.go`).
+- Wrap errors with `fmt.Errorf("doing X: %w", err)` to add context while
+  preserving the underlying error for `errors.Is` / `errors.As`.
+
+## Testing Patterns
+
+- **Scope:** unit tests live next to the code they test
+  (`*_test.go`). `task test` runs `go test ./internal/...`.
+- **Framework:** `github.com/stretchr/testify` — `require` for fatal
+  assertions, `assert` for non-fatal, `mock` for mock interactions.
+- **Mocks:** generated mockery mocks with the **expecter** API:
+  ```go
+  repo.EXPECT().Create(mock.Anything, expectedParams).
+      Return(domain.Course{ID: "c1"}, nil).Once()
+  ```
+  Note: when the generated mock does not yet implement every interface method,
+  tests embed the mock and add the missing methods (see the `fullRepo` pattern
+  in `internal/kurious/app/command/command_test.go`).
+- **Logger:** tests use a `quietLogger()` helper that discards output
+  (`slog.New(slog.NewTextHandler(io.Discard, nil))`).
+- **Adapter tests:** `internal/kurious/adapters/sqlite_*_test.go` exercise the
+  real SQLite repositories against an in-memory/temp database.
+- **Conventions:** table-driven where appropriate; use `context.Background()`
+  in tests; assert on wrapped errors with `assert.ErrorIs` and message
+  fragments with `assert.Contains`.
+
+## Notes for Agents
+
+- Run `task generate` before linting/testing if you touched any `.templ` file.
+- Do not re-introduce YDB as a working engine without updating
+  `service.NewApplication` and the migration story (currently SQLite-only).
+- Generated files (`*_templ.go`, `mocks/*.go`) are committed — regenerate and
+  commit them alongside source changes.
+- `*.json`, `*.sqlite`, `bin/`, and `*.log` are gitignored; do not commit
+  local configs or databases.

frx	6d1f526394	fix(issue-1): Pagination resets filters Move pagination logic to preserve filter query parameters (school_id, order_by, asc, per_page) when navigating between pages. - Added QueryParams field to Pagination struct and pageURL() helper - Server-side: buildListCoursesQueryParams() encodes active filters into pagination links as query string - Client-side: setupPaginationLinks() intercepts pagination link clicks, reads current filter state from DOM selects, and constructs full URLs with all parameters preserved - Added data-paginated/data-base-url/data-current-page attributes to pagination nav for JS targeting Closes #1	2026-07-03 16:16:39 +00:00
