React ePub reader

An ePub-reader for react powered by EpubJS #react #epubjs #webpack #babel #standardjs

See demo

In beta

Since it the underlaying library is using epub.js we need their v0.3 version to be finalized which bring commom modules to the library. Write now we use a custom fork of the work in progress branch.

About

epub.js is a great library, and this is a wrapper for this library, making it easier to use in a React-app.

import {
  EpubView, // Underlaying epub-canvas (wrapper for epub.js iframe)
  EpubViewStyle, // Styles for EpubView, you can pass it to the instance as a style prop for customize it
  ReactReader, // A simple epub-reader with left/right button and chapter navigation
  ReactReaderStyle // Styles for the epub-reader it you need to customize it
} from 'react-reader'

Usage

npm install react-reader --save

And in your react-component...

import React, {Component} from 'react'
import {ReactReader} from 'react-reader'

class App extends Component {
  render () {
    return (
      <div style={{position: 'relative', height: '100%'}}> // * Container needs a height..
        <ReactReader 
          url={'/alice.epub'} 
          title={'Alice in wonderland'}
          location={'epubcfi(/6/2[cover]!/6)'}
          locationChanged={(epubcifi) => console.log(epubcifi)}
        />
      </div>
    )
  }
}

ReactReader props

• url [string, required] - url to the epub-file, if its on another domain, remember to add cors for the file
• title [string] - the title of the book, displayed above the reading-canvas
• loadingView [element] - if you want to customize the loadingView
• showToc [bool] - wheather to show the toc / toc-nav
• location [string, number] - set / update location of the epub
• locationChange [func] - a function that recives the current location while user is reading
• tocChange [func] - when the the reader has parsed the book you will recive an array of the chapters

Container needs a height.. The ReactReader will expand to 100% of width/height, so be sure to set a height on the parent element, either with position it absolute of window, set height or use paddingTop for proporsjonal scaling.

Optional use the underlaying EpubView

This is just the plain epub canvas, you will then need to implement the reader stuff like chapter (toc) navigation and next/prev buttons. Take a look at the implemention in ReactReader.js

import React, {Component} from 'react'
import {EpubView} from 'react-reader'

class App extends Component {
  render () {
    return (
      /* The ReactReader will expand to 100% of width/height, so be sure to set a height on the parent element, either with position it absolute of window, set height or use paddingTop for proporsjonal scaling */
      <div style={{position: 'relative', height: '100%'}}>
        <EpubView 
          url={'/alice.epub'} 
          location={'epubcfi(/6/2[cover]!/6)'}
          locationChanged={(epubcifi) => console.log(epubcifi)}
          tocChanged={(toc) => console.log(toc)}
        />
      </div>
    )
  }
}

EpubView props

• url [string, required] - url to the epub-file, if its on another domain, remember to add cors for the file
• loadingView [element] - if you want to customize the loadingView
• location [string, number] - set / update location of the epub
• locationChange [func] - a function that recives the current location while user is reading
• tocChange [func] - when the the reader has parsed the book you will recive an array of the chapters
