React Native OpenTok is wrapper over native TokBox OpenTok SDK. The OpenTok platform, developed by TokBox, makes it easy to embed high-quality interactive video, voice, messaging, and screen sharing into web and mobile apps. OpenTok uses WebRTC for audio-video communications 👀🎧. For more info on how OpenTok works, check out OpenTok Basics.

Installation

React native OpenTok SDK depends on native OpenTok SDK implementations. You need to integrate OpenTok SDK into your existing application. Following steps needs to be done in order to have library working correctly:

Add library using yarn 📦 (or npm):

yarn add react-native-opentok

iOS

1. Install CocoaPods on your computer.
2. Within you application ios/ directory please run pod init.
3. Replace content within your brand-new Podfile with:

source 'https://github.com/CocoaPods/Specs.git'

platform :ios, '9.0'

target '<YOUR_PROJECT_NAME>' do
  node_modules_path = '../node_modules'

  pod 'yoga', path: "#{node_modules_path}/react-native/ReactCommon/yoga/yoga.podspec"
  pod 'React', path: "#{node_modules_path}/react-native"

  pod 'RNOpenTok', path: "#{node_modules_path}/react-native-opentok/ios"
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "React"
      target.remove_from_project
    end
  end
end

4. Run pod install.
5. Open <YOUR_PROJECT_NAME>.xcworkspace file (you'll need to use it as a starting file from now on).
6. Add OPENTOK_API_KEY key to your Info.plist:

<key>OPENTOK_API_KEY</key>
<string>YOUR_API_KEY</string>
<key>NSCameraUsageDescription</key>
<string>${PRODUCT_NAME} Camera Usage</string>
<key>NSMicrophoneUsageDescription</key>
<string>${PRODUCT_NAME} Microphone Usage</string>

7. Run the project 🎉.

Android

1. Run react-native link.
2. Edit your android/build.gradle file and update allprojects section:

allprojects {
    repositories {
        ...
        maven {
            url "http://tokbox.bintray.com/maven"
        }
    }
}

3. Add OPENTOK_API_KEY to your AndroidManifest.xml(within <application> tag):

<meta-data android:name="OPENTOK_API_KEY" android:value="YOUR_OPENTOK_API_KEY" />

4. Run the project 🎉.

Components

Publisher

Component used for publishing the video to the stream.

Available props:

• sessionId: string - ID of the session (you need to connect it before using this component).
• onPublishStart?: Function - Invoked when publishing starts. Optional.
• onPublishStop?: () => void - Invoked when publishing stops. Optional.
• onPublishError?: () => void - Invoked when publish error occurs. Optional.
• mute?: Boolean - This props tells Publisher if should publish audio as well or not. Optional. Defaults to false.
• video?: Boolean - This props tells Publisher if should publish video as well or not. Optional. Defaults to true.
• screenCapture?: boolean - Stream screen if true instead of camera.
• screenCaptureSettings?: { fps?: number } - Screen sharing settings
  • fps?: number - Specify frames per second for a stream (default: 15)
• every View property.

Available methods:

• switchCamera(): switches to the next camera. Goes back to first one when out of cameras.

import { Publisher } from 'react-native-opentok'
<Publisher
  style={{ height: 100, width: 200 }}
  sessionId={sessionId} 
  onPublishStart={() => { console.log('started')}} 
/>

Subscriber

Component used for subscribing to the stream.

Available props:

• sessionId: string - ID of the session (you need to connect it before using this component).
• onSubscribeStart?: Function - Invoked when stream starts. Optional.

import { Subscriber } from 'react-native-opentok'

<Subscriber
  style={{ height: 100, width: 200 }}
  sessionId={sessionId} 
  onSubscribeStart={() => { console.log('started')}} 
/>
