quick-epub

Quickly generate valid EPUB 3.0.1 documents.

This library is based on cyrilis' epub-gen, and is more of a proof-of-concept than an actual library. It was used to learn about the EPUB specification.

Will not

• Validate your passed HTML files
• Process images in said HTML files

Installation

// import the module

const data = {
  title: "White Fang",
  author: ["Jack London"],
  chapters: [
    {
      title: "CHAPTER I - THE TRAIL OF THE MEAT",
      content: "Dark spruce forest frowned on either side the frozen waterway."
    },
    {
      title: "CHAPTER II - THE SHE-WOLF",
      content: "Breakfast eaten and the slim camp-outfit lashed to the sled..."
    },
    {
      title: "CHAPTER III - THE HUNGER CRY",
      content: "The day began auspiciously."
    }
  ]
};

// create epub
epub
  .createFile(data)
  .then(() => console.log("book done."))
  .catch(e => console.error(e));
