//--------------- HOW TO ENCODE BASE64 ON NODEJS ----------------------
//create a buffer of the text "Hello World"
var buffer = Buffer.from('Hello World');
//buffer result is: <Buffer 48 65 6c 6c 6f 20 57 6f 72 6c 64>

var string64 = buffer.toString('base64');
// .toString('base64') allow to encode it to base64
// result is: SGVsbG8gV29ybGQ=

// Can be use combined together like these
console.log(Buffer.from('Hello World').toString('base64'));
// result is: SGVsbG8gV29ybGQ=
