html-epub
This module is responsible for converting an array of HTML chapters (plus a book metadata object) into an EPUB archive.
The output is a stream which can either be piped to an HTTP response or output to a file.
See pubsweet-component-epub for an example implementation.
Install
npm install html-epub
or
yarn add html-epub
Example usage in Express
app.use('/books/:book/epub', (req, res, next) => {
// book must have `identifier`, `title` and `updated` properties
const book = BookService.get(req.params.book)
// each part must have `title` and `content` (HTML) properties
const parts = book.chapters.map(chapter => ({
title: chapter.title,
content: chapter.source
}))
// the base path for relative image URLs
const resourceRoot = path.join(__dirname, 'uploads')
const epub = new HTMLEPUB(book, {resourceRoot, stylesRoot})
// pipe the zip file to the response stream
epub.load(parts).then(() => epub.stream(res))
})
