poly-ebook-server

poly-ebook-server

WebApp (Client/Server) for own ebook content: comics, pdfs and epubs (cbr,cbz,cb7,epub,pdf,...).

This tool serves ebooks of given directories (and their sub directories). Depending on the bookExtensions option it shows comics, ebooks or something else. You can have poly-ebook-server display covers in a grid.

A cover must be generated as a jpg image file at the same directory. The name must be derived from the ebook file name by changing its suffix (book “abc.cbr” -> thumb file “abc.jpg”).

In the browser: all books are displayed in a thumb view. This view is optimized for a large number of books (Polymer iron-list). With help of a simple text input one can filter the list of the books. One can download a book, can send it (as link or attachment), or delete it (move to a predefined trash folder). An epub can be read online (in the browser).

Technology: Server based on node.js, client based on Google Polymer.

Preamble

I use this tool to get an overview of my ebooks. With my iPad and Android tablet I can grabble my hole collection. An ebook can be downloaded to the tablet by a simple click. In a later version I will integrate a comic online view, an internet search (to fetch book detail information), a toggle view (grouping books) and so on. Feel free to give me feedback!

Second reason for coding this is learning Google Polymer #UseThePlatform.

Getting started

ebook-cover-generator

This tool doesn't generate thumbs of your ebooks. If you want to do this, you can use ebook-cover-generator. On Mac OS X I recommend this tool: cover-generator-by-quicklook.

Installation

Create an empty folder. Open your shell (console) and navigate to this folder. Enter:

npm i poly-ebook-server

A directory named node_modules is created with some sub folders. Navigate to node_modules/poly-ebook-server:

cd node_modules/poly-ebook-server

Edit node start file (dev.js or prod.js) and adapt the configuration:

open dev.js

Start app with:

node dev.js

In case of an error have a look at clientRoot: __dirname + '/../client(/build/bundled)' and the baseDir:....

Usage (script)

var server = require('poly-ebook-server');
server.start(options<Object>);

Examples

Example with 3 start directories

This is an example for three different ebook types. In the json structure we have three sections (see below). Each section will be rendered as a tab in the browser. Each section has a start directory. All files in this directory and it's sub directories which fits to the file extension(s), will be displayed below the corresponding tab. If for a file a jpg exist, this will be display in the selected dimension (thumbsDims and dimIndex). The user has the possibility to change the thumb size at runtime.

In case of an error have a look at clientRoot: __dirname + '/../client'.
