poltak-epub-parser

A lightweight EPUB parsing library based on zip.js. It extracts metadata, chapters, a table of contents, and a combined text stream from an EPUB file.

It is intended for browser use only (not Node).

Install

npm install poltak-epub-parser

Usage

import { parseEpub } from 'poltak-epub-parser'

const input = document.querySelector('input[type="file"]')

input.addEventListener('change', async () => {
    const file = input.files?.[0]
    if (!file) return

    const data = await parseEpub(file)
    console.log(data.title)
    console.log(data.author)
    console.log(data.tableOfContents)
})

API

parseEpub(file: File | Blob): Promise<EpubData>

Parses an EPUB file and returns:

• title: string
• author: string
• chapters: array of { id, title, content, order, wordStartIndex, wordCount }
• tableOfContents: array of { title, href, order, wordStartIndex }
• allText: combined text for speed-reading and indexing

Notes

• This library depends on browser APIs (DOMParser, File, Blob) and does not support Node.
