Have A Bug/Feature You Care About?

We :heart: open source. We work on the things that are important to us when we're able to work on them. Have an issue you care about?

Overview

A react-native wrapper for https://readium.org/. At a high level this package allows you to do things like:

• Render an ebook view.
• Register for location changes (as the user pages through the book).
• Register for the Table of Contents (so that you can display things like chapters in your app)
• Control settings of the Reader. Things like:
  • Dark Mode, Light Mode, Sepia Mode
  • Font Size
  • Page Margins
  • More (see the Settings documentation in the API section)
• Etc. (read on for more details. :book:)

Installation

Prerequisites

1. iOS: Requires an iOS target >= 13.0 (see the iOS section for more details).
2. Android: Requires compileSdkVersion >= 31 (see the Android section for more details).

Install Module

NPM

npm install react-native-readium

Yarn

yarn add react-native-readium

iOS

Due to the current state of the Readium swift libraries you need to manually update your Podfile (see more on that here).

# ./ios/Podfile
...
platform :ios, '13.0'

...

target 'ExampleApp' do
  config = use_native_modules!
  ...
  pod 'GCDWebServer', podspec: 'https://raw.githubusercontent.com/readium/GCDWebServer/3ec154d358f26858071feaa6429e0f1c16bb11bd/GCDWebServer.podspec', modular_headers: true
  pod 'R2Shared', podspec: 'https://raw.githubusercontent.com/readium/swift-toolkit/2.4.0/Support/CocoaPods/ReadiumShared.podspec'
  pod 'R2Streamer', podspec: 'https://raw.githubusercontent.com/readium/swift-toolkit/2.4.0/Support/CocoaPods/ReadiumStreamer.podspec'
  pod 'R2Navigator', podspec: 'https://raw.githubusercontent.com/readium/swift-toolkit/2.4.0/Support/CocoaPods/ReadiumNavigator.podspec'
  pod 'Minizip', modular_headers: true
  ...
end

Finally, install the pods:

pod install

Android

You might need to add jcenter if you're getting a build failure on android:

// android/build.gradle
...

allprojects {
    repositories {
        ...
        // required by react-native-readium https://github.com/readium/kotlin-toolkit/issues/31
        jcenter()
    }
    ...
}
...

If you're not using compileSdkVersion >= 31 you'll need to update that:

// android/build.gradle
...
buildscript {
    ...
    ext {
        ...
        compileSdkVersion = 31
...

Usage

import React, { useState } from 'react';
import { ReadiumView } from 'react-native-readium';
import type { File } from 'react-native-readium';

const MyComponent: React.FC = () => {
  const [file] = useState<File>({
    url: SOME_LOCAL_FILE_URL,
  });

  return (
    <ReadiumView
      file={file}
    />
  );
}

Take a look at the Example App for a more complex usage example.

Supported Formats & DRM

Format Support

Missing a format you need? Reach out and see if it can be added to the roadmap.

DRM Support

DRM is not supported at this time. However, there is a clear path to support it via LCP and the intention is to eventually implement it.

API

View Props

:warning: Web vs Native File URLs

Please note that on web the File.url should be a web accessible URL path to the manifest.json of the unpacked epub. In native contexts it needs to be a local filepath to the epub file itself on disk. If you're not sure how to serve epub books take a look at this example which is based on the dita-streamer-js project (which is built on all the readium r2-*-js libraries)

Contributing

Release

The standard release command for this project is:

yarn version

This command will:

1. Generate/update the Changelog
2. Bump the package version
3. Tag & pushing the commit

e.g.
