This is a typescript library that create an epub structor. This library dose not save the structored epub file, you have to do that your self. This library work for react, react-native and web. It simple create a structored epub object that you could save it to your desired location later on.
npm install @cd-z/epub-constructor
import EpubFile from 'epub-constructor'
var epub = new EpubFile({
title: "example",
fileName: "examplefile" // optional, it will take title if not set
language: "en",
description: "this is a epub test",
stylesheet:{
p: {
width:"100%"
}
},
chapters:[{
fileName: "examplefile" // optional, it will take title if not set
title: "Air born",
htmlBody: "<p>this is chapter 1</p>"
},{
title:"chapter 2",
htmlBody: "<p>this is chapter 1</p>"
}]
});
var file = await epub.constructEpub();
// save the file to your deviceThis is what file will containe

]You will have to create those files and make a zip file there after.
You could also read an epub file and begin to modify or append chapters there after.
// file have to be extracted by your self. It should look like the above json and be created by this library
var settings = EpubFile.load(file);
settings.chapters.push({
title: 'chapter 3',
htmlBody: '<p>this is chapter 3</p>',
});
var epub = new EpubFile(settings);
var file = await epub.constructEpub();
// save the file to your deviceThis library is new and it may containe some bugs so please report those. Will be glad if someone is able to create an android and IOS modules that can create the actual epub(zip) file
