Remove this line:

var ConsolePanel = require('react-native-console-panel').displayWhenDev();

And also remove:

{ConsolePanel}

To log something to the console in React Native, simply do this:

console.log('Hi from React Native');

To see the console output, if you're on Mac OS or Linux, run this in a terminal window:

$ adb logcat | grep ReactNativeJS

If you're on Windows, see this StackOverflow question: How to easily view and filter Android's logcat in Windows?

Reading the logs is also documented in the Getting Started guide.

UPDATE: You can now run react-native log-ios or react-native log-android to see the logs in the console.
