How can I get the device's ip on React Native?

Question

In node we would use require('os') but we cannot do such thing on react native. Any ideas?

Answer 1

There's a ReactNative library for getting information about the devices network:

react-native-network-info

// require module
var NetworkInfo = require('react-native-network-info');

// Get Local IP
NetworkInfo.getIPAddress(ip => {
  console.log(ip);
});

Answer 2

import publicIP from 'react-native-public-ip';

publicIP()
.then(ip => {    
  console.log(ip);
  // '47.122.71.234'
})
.catch(error => {
  console.log(error);
  // 'Unable to get IP address.'
});
