Very nice article. Explained in clear and concise manner. I am new to react native and constantly facing this issue:

Runtime is not ready.Make sure your packager server is running.

It is an open issue and i have tried everything from https://github.com/facebook/react-native/issues/6682 and https://facebook.github.io/react-native/docs/debugging.html but to no avail. My app loads correctly from simulator and works for 10–15 seconds after which a red screen comes up alerting me of this issue. Sometimes it loads for more duration and sometimes less. Any insights?
