Usage

Create an Epub

import EpubBuilder, { FsSettings, ReadDirItem, EpubChapter, EpubSettings, EpubLoader, getValidFileNameByTitle } from 'react-native-epub-creator';

  // Can be used to visualize the progress
  const [progress, setProgress] = React.useState('');
  EpubBuilder.onProgress = (progress, file, operation) => {
    setProgress(Math.round(progress) + '  |  ' + file + '  |  ' + operation);
  };

  var epub = new EpubBuilder({
      title: "example",
      fileName: getValidFileNameByTitle("examplefile-%1"), // optional, it will take title if not set
      language: "en",
      description: "this is a epub test",
      stylesheet: {
        p: {
          width: "100%"
        }
      },
      // If chapters are defined, epub.save() can instantly be called
      chapters: [{
        title: "Air born",
        htmlBody: "<p>this is chapter 1</p>"
      }, {
        title: "chapter 2",
        htmlBody: "<p>this is chapter 2</p>"
      }]
    }, 
      // Optional path to destination folder
      // Opens a folder picker if undefined
      RNFS.DownloadDirectoryPath
  );
  try{     
    await epub.prepare();
    await epub.addChapter({
      title: 'CH 1',
      htmlBody: '<p>Some content</p>',
    });
    await epub
      .save()
      .then((value: string) => console.log(value))
  }catch(error){
   // remove the temp created folder
   await epub.discardChanges();
  }

Read an Existing Epub file

Currently not supported

  var path = RNFS.DownloadDirectoryPath +"/example.epub";
  var localProgress=(progress, file)=> {

  })
  var epub = await EpubLoader(path, RNFS, localProgress);
  // you could add new chapters 
  epub.addChapter({
        fileName: getValidFileNameByTitle("examplefile-%1Chapter1"), // optional, it will take title if not set
        title: "chapter 3",
        htmlBody: "<p>this is chapter 3</p>"
      });
    try{
      // save and create the .epub file
      var epubFilePath = await epub.save();
    }catch(error){
     // remove the temp created folder
     await epub.discardChanges();
    }
