Nodepub3 is used to create EPUB 3 e-books in nodejs that reference to kcartlidge/nodepub and mohannadize/nodepub-lite.
Nodepub3 is a Node module which can be used to create EPUB 3 documents.
<body dir="rtl">npm i nodepub3
# or use pnpm
pnpm i nodepub3
Then import it for use:
import Nodepub3 from 'nodepub3'
Here's some sample metadata:
import fs from 'fs-extra'
import Nodepub3, { Metadata } from 'nodepub3'
const metadata: Metadata = {
id: 'isbn:278-123456789',
cover: {
name: 'cover.png',
// base64 encoded resource, or Buffer
data: fs.readFileSync('cover.png')
},
title: 'Unnamed Document',
creator: {
value: 'Anonymous',
meta: {
'file-as': 'Anonymous'
}
},
subject: ['Sample', 'Example', 'Test'],
copyright: 'Anonymous, 1980',
publisher: 'My Fake Publisher',
publicationDate: new Date('2000-12-31'),
language: 'en',
description: 'A test book.',
source: 'http://www.kcartlidge.com'
}
Call the constructor method with the aforementioned metadata object detailing your book.
const epub = new Nodepub3(metadata)
The bulk of the work is adding your content.
Call addChapter on your new document with a title and the HTML/TEXT contents for each chapter in turn.
epub.addChapter(title, content[, isNormalText, depth])
For example:
epub.addChapters(
{
title: 'Copyright',
content: '<p>...</p>\n<p>...</p>'
},
{
title: 'Chapter 1',
content: '...\n...',
// content will convert to "<p>...</p>\n<p>...</p>"
isNormalText: true
}
)
Support nested table of contents hierarchies.
/**
* Table of Contens:
* 1
* 2
* 2.1
* 2.2
* 2.2.1
* 3
*/
epub.addChapters(
{ title: '1', content: '' },
{ title: '2', content: '' },
{ title: '2.1', content: '', depth: 1 },
{ title: '2.2', content: '', depth: 1 },
{ title: '2.2.1', content: '', depth: 2 },
{ title: '3', content: '' }
)
You can inject basic CSS style into your book.
epub.addStyle('p { text-indent: 2em; }')
For example:
epub.addResource('f1.png', fs.readFileSync('image.png'))
epub.addResources(
{
name: 'f2.mp3',
data: fs.readFileSync('audio.mp3')
},
{
name: 'f3.mp4',
data: fs.readFileSync('video.mp4')
},
{
name: 'f4.ttf',
data: fs.readFileSync('font.ttf')
}
)
use resource in chapter case:
<img src="../res/f1.png" />
<audio src="../res/f2.mp3" controls="controls" />
<video src="../res/f3.mp4" controls="controls" />
use resource in CSS style case:
@font-face {
font-family: 'f4';
src: url('res/f4.ttf');
}
Note that Nodepub3 is asynchronous, actionable using async/await.
// This will generate an epub file `example.epub`
;(async () => {
try {
await epub.create('example.epub')
} catch (e) {
console.error(e)
}
})()
