Usage
import { parseEpub } from 'epub2md'
const epubObj = await parseEpub('/path/to/file.epub')
console.log('epub content:', epubObj)
parseEpub(target: string | buffer, options?: ParserOptions): EpubObject
target
type: string
or buffer
It can be the path to the file or file's binary string or buffer
options: ParserOptions
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 aboutsrc
andhref
, thesrc
andhref
in raw html stay untouched, but thetoHtmlObjects
method resolvessrc
to base64 string, and altershref
so that they make sense in the parsed epub. And the parsedhref
is something like#{sectionId},{hash}
.
expand?: boolean
convertToMarkdown?: (htmlstr: string) => string
use custom convert function, you can use turndown or node-html-markdown etc.
