DjVu.js is a program library for working with .djvu online. It's written
in JavaScript and can be run in the web browsers without any connection with the
server. DjVu.js can be used for splitting (and concatenation) of .djvu files,
rendering pages of a .djvu document, converting (and compressing) images
into .djvu documents and for analyzing of metadata of .djvu documents.
DjVu.js Viewer is an app which uses DjVu.js in order to render DjVu documents. The app may be easily included into any html page. You can look at it and try it out on the official website (the link is below).
DjVu.js Viewer browser extension. By and large it's a copy of the viewer,
but also it allows opening links to .djvu files right in the browser without
explicit downloading of a file. The links to the extension are below.
DjVu.js - это программная библиотека написанная на JavaScript и
предназначенная для работы с файлами формата .djvu онлайн. DjVu.js
ориентирована на исполнение в браузере пользователя без связи с сервером.
Библиотека может быть использована для разделения (объединения) файлов .djvu,
преобразования картинок в документы .djvu, отрисовки страниц
документов .djvu, а также для анализа мета данных и структуры .djvu
документов.
DjVu.js Viewer - приложение, которое можно легко встроить в любую html-страницу. Данное приложение служит для просмотра документов DjVu непосредственно в браузере. Вы можете ознакомиться с ним по ссылке ниже.
Расширение для браузера DjVu.js Viewer. По большей части это копия
приложения DjVu.js Viewer, однако также расширение позволяет открывать ссылки
на .djvu файлы прямо в браузере, не скачивая файл явно. Ссылки на расширение
доступны ниже.
If you want to add a new translation to the viewer read here how to do it.
If you have Node.js (10.x or higher) installed, after you cloned the repository, run
npm run install
npm run build
in the root folder of the repository. The command will install all dependencies and create bundles of the library and of the viewer (the build folder should appear).
Also there is another way to do the same operations:
npm run make
The command will clean all git-ignored files, install all the dependencies and
build the library and the viewer. However, you should have git installed of
course and the repository should have the .git folder (there is no one in the
source code uploaded to the browser extensions websites).
You have to build the library once. You can archive it via npm run make. Then
you can start the viewer:
cd viewer
npm start
After the two commands above are executed (install and build), the extension
folder will contain all the necessary files, that is to say, the folder is an
unpacked extension. If you want to pack the extension, you should have
the web-ext module installed globally, to wit, npm install web-ext -g, and
then just change the directory:
cd extension
and run
web-ext build
and the packed version of the extension will appear in the extension folder.
If you have some problems, read the technical documentation or create an issue. Also you can download the library from the official website. (All links are below).
