Can't find variable: Buffer

Question

I\'m trying to use node modules in my react-native app, and I\'m taking the ReactNativify approach here.

I\'m all set up now, and I got the crypto package to load i

Answer 1

first install the following

yarn add buffer process babel-plugin-react-native-nodeify-hack

Then add to your babel settings .babelrc

{
  "presets": ["react-native"],
  "plugins": ["babel-plugin-react-native-nodeify-hack"]
}

Import the buffer and process modules manually. In your index.ios.js and index.android.js, add this to the first line:

import process from 'process';
import buffer from 'buffer';
global.Buffer = buffer.Buffer

try to stop the running React Native Packager, and run:

rm -rf $TMPDIR/react-*

and start it again

You are good to go!
