 # История изменений

+## 2026-04-06 16:00 UTC – Сохранение загрузки в PostgreSQL (ключ «Название»)
+
+**Проблема:** Нужно хранить выгрузки в БД: по ключу «Название» обновлять запись или вставлять новую.
+
+**Решение:** Добавлен API на Node.js (Express + `pg`), таблица `incidents (number_key PK, data JSONB)`. После разбора файла фронт вызывает `POST /api/incidents/sync`; при открытии — `GET /api/incidents`. Nginx на `sd.gen7x.ru` проксирует `/api/` на `127.0.0.1:3910`. Контейнер `omc-sd-api` в сети `docker_gen7x_network`, БД `omc_sd_monitor` в существующем Postgres.
+
+**Изменения:** каталог `server/`, `docker-compose.yml` (сервис `api`), `.env.example`, `index.html`, `README.md`.
+
+**Проверка:** `docker compose up -d api`, `GET /api/health`, загрузка `sample-data.csv` на https://sd.gen7x.ru/.

 ## 2026-04-06 14:00 UTC – Загрузка из Excel

 **Проблема:** Нужна загрузка выгрузки в формате Excel при той же структуре колонок, что у CSV/JSON.

+Дашборд инцидентов ServiceDesk: KPI, диаграммы, таблица, разбивка по сотрудникам. Загрузка файла (CSV, JSON, Excel) **сохраняется в PostgreSQL**: ключ записи — целое число из поля **«Название»**; при совпадении ключей строка **обновляется**, иначе **добавляется**. При открытии страницы данные **подгружаются из базы** (если API доступен).

-## Запуск
+## База данных и API

-### Локально
+- БД: PostgreSQL, база `omc_sd_monitor`, таблица `incidents` (`number_key` PK, `data` JSONB с полями как в экспорте).
+- API (Node.js, Express): `GET /api/incidents`, `POST /api/incidents/sync`, `GET /api/health`.
+- Контейнер `omc-sd-api` в Docker-сети `docker_gen7x_network`, порт на хосте `127.0.0.1:3910`; Nginx проксирует `https://sd.gen7x.ru/api/` → этот порт.

-Откройте в браузере файл [`index.html`](index.html) (двойной клик или `file://`). Для быстрой проверки можно загрузить [`sample-data.csv`](sample-data.csv).
+Создание базы (один раз, от суперпользователя Postgres):

-### Docker
+```sql
+CREATE DATABASE omc_sd_monitor;
+```
+
+В `.env` задайте `DATABASE_URL` (см. `.env.example`). Спецсимволы в пароле — в URL-кодировании (например `/` → `%2F`).
+
+Запуск только API на сервере:

 ```bash
 cd /opt/omc-servicedesk-monitor
-cp .env.example .env   # при необходимости измените PORT
-docker compose up -d
+# .env с DATABASE_URL
+docker compose up -d api
 ```

-Страница: `http://localhost:${PORT}` (по умолчанию 8080).
+## Запуск
+
+### Локально (только UI)
+
+Откройте [`index.html`](index.html). Без API сохранение в БД недоступно (будет сообщение об ошибке после разбора файла). Пример данных: [`sample-data.csv`](sample-data.csv).
+
+### Docker (статика + опционально API)
+
+```bash
+cd /opt/omc-servicedesk-monitor
+cp .env.example .env   # задать DATABASE_URL для API
+docker compose up -d     # web на PORT, api на 3910
+```
+
+Страница статики: `http://localhost:${PORT}` (по умолчанию 8080).
