-Веб-сервер для поиска по inpx-коллекции.
+Веб-сервер для поиска по .inpx-коллекции.
+Выглядит это так: https://lib.omnireader.ru
+
+.inpx - индексный файл для импорта\экспорта информации из базы данных сетевых библиотек
+в базу каталогизатора [MyHomeLib](https://alex80.github.io/mhl/)
+или [freeLib](http://sourceforge.net/projects/freelibdesign)
+или [LightLib](https://lightlib.azurewebsites.net)
+
+Просто поместите приложение `inpx-web` в папку с .inpx-файлом и файлами библиотеки (zip-архивами) и запустите.
+Сервер будет доступен по адресу http://127.0.0.1:12380
+
+После открытия веб-приложения в бразуере, для быстрого понимания того, как работает поиск, воспользуйтесь памяткой (кнопка со знаком вопроса).

+
+<a id="usage" />
+
+## Использование
+Поместите приложение `inpx-web` в папку с .inpx-файлом и файлами библиотеки и запустите.
+Там же, при первом запуске, будет создана рабочая директория `.inpx-web`, в которой хранится
+конфигурационный файл `config.json`, файлы базы данных, журналы и прочее.
+
+По умолчанию сервер будет доступен по адресу http://127.0.0.1:12380
+
+<a id="cli" />
+
+### Параметры командной строки
+Запустите `inpx-web --help`, чтобы увидеть список опций:
+```console
+Usage: inpx-web [options]
+
+Options:
+  --help              Показать опции командной строки
+  --host=<ip>         Задать имя хоста для веб сервера, по умолчанию: 0.0.0.0
+  --port=<port>       Задать порт для веб сервера, по умолчанию: 12380
+  --app-dir=<dirpath> Задать рабочую директорию, по умолчанию: <execDir>/.inpx-web
+  --lib-dir=<dirpath> Задать директорию библиотеки (с zip-архивами), по умолчанию: там же, где лежит файл приложения
+  --inpx=<filepath>   Задать путь к файлу .inpx, по умолчанию: тот, что найдется в директории библиотеки
+  --recreate          Принудительно пересоздать поисковую БД при запуске приложения
+```
+
+<a id="config" />
+
+### Конфигурация
+При первом запуске в рабочей директории будет создан конфигурационный файл `config.json`:
+```js
+{
+    // пароль для ограничения доступа к веб-интерфейсу сервера
+    "accessPassword": "",
+
+    // содержимое кнопки-ссылки "(читать)", если не задано - кнопка "(читать)" не показывается
+    // пример: "https://omnireader.ru/#/reader?url=${DOWNLOAD_LINK}"
+    // на место ${DOWNLOAD_LINK} будет подставлена ссылка на скачивание файла книги
+    "bookReadLink": "",
+
+    // включить(true)/выключить(false) журналирование
+    "loggingEnabled": true,
+
+    // максимальный размер кеша каждой таблицы в БД, в блоках (требуется примерно 1-10Мб памяти на один блок)
+    // если надо кешировать всю БД, можно поставить значение от 1000 и больше
+    "dbCacheSize": 5,
+
+    // максимальный размер в байтах директории закешированных файлов в <раб.дир>/public/files
+    // чистка каждый час
+    "maxFilesDirSize": 1073741824,
+    
+    // включить(true)/выключить(false) кеширование запросов на сервере
+    "queryCacheEnabled": true,
+
+    // периодичность чистки кеша запросов на сервере, в минутах
+    // 0 - отключить чистку
+    "cacheCleanInterval": 60,
+
+    // периодичность проверки изменений .inpx-файла, в минутах
+    // если файл изменился, поисковая БД будет автоматически пересоздана
+    // 0 - отключить проверку
+    "inpxCheckInterval": 60,
+
+    // включить(true)/выключить(false) режим работы с малым количеством физической памяти на машине
+    // при включении этого режима, количество требуемой для создания БД памяти снижается примерно в 1.5-2 раза
+    // во столько же раз увеличивается время создания
+    "lowMemoryMode": false,
+
+    // включить(true)/выключить(false) полную оптимизацию поисковой БД
+    // ускоряет работу поиска, но увеличивает размер БД в 2-3 раза при импорте INPX
+    "fullOptimization": false,
+
+    // включить(true)/выключить(false) режим "Удаленная библиотека" (сервер)
+    "allowRemoteLib": false,
+
+    // включить(Object)/выключить(false) режим "Удаленная библиотека" (клиент)
+    // подробнее см. раздел "Удаленная библиотека" ниже
+    "remoteLib": false,
+
+    // настройки веб-сервера
+    "server": {
+        "host": "0.0.0.0",
+        "port": "12380"
+    }
+}
+```
+
+При необходимости, можно настроить нужный параметр в этом файле вручную. Параметры командной
+строки имеют больший приоритет, чем настройки из `config.json`.
+
+<a id="remotelib" />
+
+### Удаленная библиотека
+
+В случае, когда необходимо физически разнести веб-интерфейс и библиотеку файлов на разные машины,
+приложение может работать в режиме клиент-сервер: веб-интерфейс, поисковый движок и поисковая БД на одной машине (клиент),
+а библиотека книг и .inpx-файл на другой (сервер).
+
+Для этого необходимо развернуть два приложения, первое из которых будет клиентом для второго.
+
+На сервере правим `config.json`:
+```
+    "accessPassword": "123456",
+    "allowRemoteLib": true,
+```
+
+На клиенте:
+```
+    "remoteLib": {
+    	"accessPassword": "123456",
+        "url": "ws://server.host:12380"
+    },
+```
+
+Если сервер работает по протоколу `http://`, то указываем протокол `ws://`, а для `https://` соответственно `wss://`.
+Пароль не обязателен, но необходим в случае, если сервер тоже "смотрит" в интернет, для ограничения доступа к его веб-интерфейсу.
+При указании `"remoteLib": {...}` настройки командной строки --inpx и --lib-dir игнорируются,
+т.к. файлы .inpx-индекса и библиотеки используются удаленно.
+
+<a id="filter" />
+
+### Фильтр по авторам и книгам
+
+При создании поисковой БД во время загрузки и парсинга .inpx-файла, имеется возможность
+отфильтровать авторов и книги, задав определенные критерии. Для этого небходимо создать
+в рабочей директории (там же, где `config.json`) файл `filter.json` следующего вида:
+```json
+{
+  "info": {
+    "collection": "Новое название коллекции",
+    "structure": "",
+    "version": "1.0.0"
+  },
+  "filter": "(r) => r.del == 0",
+  "includeAuthors": ["Имя автора 1", "Имя автора 2"],
+  "excludeAuthors": ["Имя автора"]
+}
+```
+При создании поисковой БД, авторы и книги из `includeAuthors` будут добавлены, а из `excludeAuthors` исключены.
+Использование совместно `includeAuthors` и `excludeAuthors` имеет мало смысла, поэтому для включения
+определенных авторов можно использовать только `includeAuthors`:
+```json
+{
+  "info": {
+    "collection": "Новое название коллекции"
+  },
+  "includeAuthors": ["Имя автора 1", "Имя автора 2"]
+}
+```
+Для исключения:
+```json
+{
+  "info": {
+    "collection": "Новое название коллекции"
+  },
+  "excludeAuthors": ["Имя автора 1", "Имя автора 2"]
+}
+```
+
+Параметр `filter` используется для более гибкой фильтрации по атрибутам записей из .inpx.
+Уберем все записи, помеченные как удаленные и исключим "Имя автора 1":
+```json
+{
+  "info": {
+    "collection": "Новое название коллекции"
+  },
+  "filter": "(inpxRec) => inpxRec.del == 0",
+  "excludeAuthors": ["Имя автора 1"]
+}
+```
+Использование `filter` небезопасно, т.к. позволяет выполнить произвольный js-код внутри программы,
+поэтому запуск приложения в этом случае должен сопровождаться дополнительным параметром командной строки `--unsafe-filter`.
+Названия атрибутов inpxRec соответствуют названиям в нижнем регистре из структуры structure.info в .inpx-файле.
+<a id="https" />
+
+### Настройка https с помощью nginx
+Проще всего настроить https с помощью certbot и проксирования в nginx (пример для debian-based linux):
+
+```sh
+#ставим nginx
+sudo apt install nginx
+```
+```
+#правим конфиг nginx
+server {
+  listen 80;
+  server_name <имя сервера>;
+  set $inpx_web http://127.0.0.1:12380;
+
+  client_max_body_size 512m;
+  proxy_read_timeout 1h;
+
+  location / {
+    proxy_pass $inpx_web;
+    proxy_http_version 1.1;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection "upgrade";
+  }
+}
+```
+```sh
+#загружаем новый конфиг
+sudo service nginx reload
+```
+Далее следовать инструкции установки https://certbot.eff.org/instructions?ws=nginx&os=debianbuster
+
+<a id="build" />
+
+### Сборка проекта
+Сборка только в среде Linux.
+Необходима версия node.js не ниже 16.
+
+```sh
+git clone https://github.com/bookpauk/inpx-web
+cd inpx-web
+npm i
+```
+
+#### Для платформы Windows
+```sh
+npm run build:win
+```
+
+#### Для платформы Linux
+```sh
+npm run build:linux
+```
+
+Результат сборки будет доступен в каталоге `dist/linux|win` в виде исполнимого (standalone) файла.
+
+<a id="development" />
+
+### Разработка
+```sh
+npm run dev
+```

+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide

+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
