Parse ePub electronic book files with Node.JS
npm install epub2epub2 is a node.js module to parse EPUB electronic book files.
NB! Only ebooks in UTF-8 are currently supported!.
this module fork from epub
npm install epub2 zipfile
Or, if you want a pure-JS version (useful if used in a Node-Webkit app for example):
npm install epub2
``ts
const EPub = require("epub2/node");
import * as EPub from 'epub2/node';
const EPub = require("epub2").EPub;
import EPub from 'epub2';
import { EPub } from 'epub2';
`
`ts`
var epub = new EPub(epubfile, imagewebroot, chapterwebroot);
Where
* epubfile is the file path to an EPUB file
imagewebroot is the prefix for image URL's. If it's /images/ then the actual URL (inside chapter HTML blocks) is going to be /images/IMG_ID/IMG_FILENAME*, IMG_ID can be used to fetch the image form the ebook with getImage. Default: /images/
chapterwebroot is the prefix for chapter URL's. If it's /chapter/ then the actual URL (inside chapter HTML links) is going to be /chapters/CHAPTER_ID/CHAPTER_FILENAME*, CHAPTER_ID can be used to fetch the image form the ebook with getChapter. Default: /links/
Before the contents of the ebook can be read, it must be opened (EPub is an EventEmitter).
`ts`
let epub = await EPub.createAsync(epubfile, imagewebroot, chapterwebroot);
`ts`
EPub.createAsync(epubfile, imagewebroot, chapterwebroot)
.then(function (epub)
{
...
})
.catch(function (err)
{
console.log("ERROR\n-----");
throw err;
})
;
`ts
epub.on("end", function(){
// epub is now usable
console.log(epub.metadata.title);
epub.getChapter("chapter_id", function(err, text){});
});
epub.parse();
`
Property of the epub object that holds several metadata fields about the book.
`ts`
epub = new EPub(...);
...
epub.metadata;
`ts`

epub.metadata[EPub.SYMBOL_RAW_DATA];
Available fields:

subject Topic of the book (Fantasy*)
date creation of the file (2006-08-12*)
* description
flow is a property of the epub object and holds the actual list of chapters (TOC is just an indication and can link to a # url inside a chapter file)
`ts`
epub = new EPub(...);
...
epub.flow.forEach(function(chapter){
console.log(chapter.id);
});
Chapter id is needed to load the chapters getChapter
property
getChapter(chapter_id, callback)
Load chapter text from the ebook.
`ts
var epub = new EPub(...);
...
epub.getChapter("chapter1", function(error, text){});
`getChapterRaw(chapter_id, callback)
Load raw chapter text from the ebook.
getImage(image_id, callback)
Load image (as a Buffer value) from the ebook.
`ts
var epub = new EPub(...);
...
epub.getImage("image1", function(error, img, mimeType){});
`getFile(file_id, callback)
Load any file (as a Buffer value) from the ebook.
`ts
var epub = new EPub(...);
...
epub.getFile("css1", function(error, data, mimeType){});
`EPub.libPromise
