yarn
(note: after this you should also run react-native link react-native-node, but in this example we already ran that for you)
Run npm run build or follow these steps manually:
The node.js project is in the directory /background, you need to install its node_modules separately from the node_modules for your React Native project:
cd background
yarn
cd ..
react-native-node insert ./background
(or ./node_modules/.bin/react-native-node insert ./background)
react-native run-android
