React Native - Linking Native API
Start
  Outgoing Links

To open a link call openURL.

Linking.openURL(url)
.catch(err => console.error('An error occurred ', err))

The preferred method is to check if any installed app can handle a given URL beforehand.

Linking.canOpenURL(url)
.then(supported => {
  if (!supported) {
    console.log('Unsupported URL: ' + url)
  } else {
    return Linking.openURL(url)
  }
}).catch(err => console.error('An error occurred ', err))

  Incomming Links

You can detect when your app is launched from an external URL.

componentDidMount() {
  const url = Linking.getInitialURL()
  .then((url) => {
    if (url) {
      console.log('Initial url is: ' + url)
    }
  }).catch(err => console.error('An error occurred ', err))
}

To enable this on iOS Link RCTLinking to your project (opens new window).

To enable this on Android, follow these steps (opens new window).
