📖 epub-parser

A powerful yet easy-to-use epub parser

The package exports a simple parser function which use epub file as input and output JavaScript object.

As it is written in TypeScript, types are already included in the package.

Install

npm install @gxl/epub-parser --save

or if you prefer yarn

yarn add @gxl/epub-parser

Usage

import { parseEpub } from '@gxl/epub-parser'

const epubObj = await parseEpub('/path/to/file.epub', {
  type: 'path',
})

console.log('epub content:', epubObj)

parseEpub(target: string | buffer, options?: object): EpubObject

target

type: string or buffer

It can be the path to the file or file's binary string or buffer

options

type: object

type(optional): 'binaryString' | 'path' | 'buffer'

It forces the parser to treat supplied target as the defined type, if not defined the parser itself will decide how to treat the file (useful when you are not sure if the path is valid).

EpubObject

The output is an object which contains structure, sections, info(private property names start with _. I don't recommend using them, since they are subscribed to change).

structure is the parsed toc of epub file, they contain information about how the book is constructed.

sections is an array of chapters or sections under chapters, they are referred in structure. Each section object contains the raw html string and a few handy methods.

• Section.prototype.toMarkdown: convert to markdown object.
• Section.prototype.toHtmlObjects: convert to html object. And a note about src and href, the src and href in raw html stay untouched, but the toHtmlObjects method resolves src to base64 string, and alters href so that they make sense in the parsed epub. And the parsed href is something like #{sectionId},{hash}.
