Node.js throws “btoa is not defined” error

Question

In my node.js application I did an npm install btoa-atob so that I could use the btoa() and atob() functions which are native in clien

Answer 1

My team ran into this problem when using Node with React Native and PouchDB. Here is how we solved it...

NPM install buffer:

$ npm install --save buffer

Ensure Buffer, btoa, and atob are loaded as a globals:

global.Buffer = global.Buffer || require('buffer').Buffer;

if (typeof btoa === 'undefined') {
  global.btoa = function (str) {
    return new Buffer(str, 'binary').toString('base64');
  };
}

if (typeof atob === 'undefined') {
  global.atob = function (b64Encoded) {
    return new Buffer(b64Encoded, 'base64').toString('binary');
  };
}
