React ePub reader

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

React wrapper for epubjs

React reader is an react-wrapper for epub.js, using the v.03 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>
    )
  }
}

See demo/App.js for an example of using the selection api in epubjs.

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
locationChanged [func] - a function that recives the current location while user is reading
tocChanged [func] - when the the reader has parsed the book you will recive an array of the chapters
styles [object] - override the default styles
epubOptions [object] - pass custom properties to the epub rendition
getRendition [func] - when epubjs has rendered the epub-file you can get access to the epubjs-rendition object here
swipeable [bool, default false] - enable swiping left/right with react-swipeable. Warning this will disable interacting with epub.js iframe content like selection

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
locationChanged [func] - a function that recives the current location while user is reading
tocChanged [func] - when the the reader has parsed the book you will recive an array of the chapters
styles [object] - override the default styles
epubOptions [object] - pass custom properties to the epub rendition
getRendition [func] - when epubjs has rendered the epub-file you can get access to the epubjs-rendition object here

Usage in cordova

There is a limitation with iframe and srcdoc so you need to add this to your config.xml to make react-reader work within an cordova application:

<allow-navigation href="about:*" />
