I find some simple way worked for me, the same api as node.

Install buffer

yarn add buffer

Usage:

console.log(Buffer.from("Hello World").toString('base64'));
console.log(Buffer.from("SGVsbG8gV29ybGQ=", 'base64').toString('ascii'));

Another way is to install this react-native-base64 package and use it as below in react native.

npm install --save react-native-base64

import base64 from 'react-native-base64'
base64.encode('Some string to encode to base64'); 
base64.decode('VGhlIG51bWJlciBpcyA2MDAwMCwgd2hpY2ggY2FuIGJlIHJlYWQgYXMgc2l4dHkgdGhvdXNhbmQuJm5ic3A7PEJSPg==')

atob and btoa are not supported in JavascriptCore but works when the app runs under Chrome debugger, because JS code runs in Chrome when debugged. There are many base64 modules. https://github.com/mathiasbynens/base64 works fine for me.
