get-epub-cover

A Node app to find and return the absolute path to the cover image of an unzipped EPUB.

Installation

• As a local package

npm i get-epub-cover

• As a CLI (Command Line Interface) Application

npm i -g get-epub-cover

Usage

NOTE: EPUB project should be an unzipped directory

• Require it
• Call it with the path to the unzipped EPUB directory as the first argument.
• Expect a promise; or, pass a callback as the second argument.

const getEpubCover = require('get-epub-cover');
 
const epubDir = './epub-project-directory';
 
/* expect a promise */
 
getEpubCover(epubDir)
  .then(data => {
    console.log(`EPUB COVER LOCATION: ${data}`);
  })
  .catch(err => {
    console.log(err);
  });
 
/* or, pass a callback */
 
getEpubCover(epubDir, (err, data) => {
  if (err) {
    console.error(err);
    return;
  }
  console.log(data);
});

CLI

• Install it globally
• CD into the path of the EPUB directory and then enter get-epub-cover without an argument

cd epub-project-directory
get-epub-cover

• Or, enter get-epub-cover followed by the absolute path (relative to the current working directory) to the EPUB directory as the first argument

get-epub-cover epub-project-directory

• The EPUB cover will be displayed in the terminal (for terminals that support colors) followed by an absolute path to the cover image.
• Otherwise, an error will be logged
