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.

• react-native >=0.49.3

Supported OpenTok SDK version:

• OpenTok SDK 2.12.+

• Installation
• API Reference
• Components
• Usage

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

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 🎉.

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 🎉.

Connects to choosen session.

const connectToSession = async () => {
  try {
    await OpenTok.connect('YOUR_SESSION_ID', 'YOUR_TOKEN');
  } catch (e) {
    console.log(e)
  }
}

Disconnects from chosen session.

OpenTok.disconnect('YOUR_SESSION_ID');

Disconnects all available sessions.

OpenTok.disconnectAll();

Send signal to chosen session.

const connectToSession = async () => {
  try {
    await OpenTok.connect('YOUR_SESSION_ID', 'YOUR_TOKEN');
  } catch (e) {
    console.log(e)
  }
}

Constants for events thrown in app. Available values:

• ON_SIGNAL_RECEIVED
• ON_SESSION_CONNECTION_CREATED
• ON_SESSION_CONNECTION_DESTROYED
• ON_SESSION_DID_CONNECT
• ON_SESSION_DID_DISCONNECT
• ON_SESSION_DID_FAIL_WITH_ERROR
• ON_SESSION_STREAM_CREATED
• ON_SESSION_STREAM_DESTROYED

Event listener, for events listed above.

OpenTok.on(OpenTok.events.ON_SIGNAL_RECEIVED, e => console.log(e));

Removes listener.

OpenTok.removeListener(OpenTok.events.ON_SIGNAL_RECEIVED);

  sessionId={sessionId} 
  onPublishStart={() => { console.log('started')}} 
/>

Component used for subscribing to the stream.
