Base64 encode a javascript object

Question

I have large Javascript objects which I would like to encode to base-64 for AWS Kinesis` It turns out that:

let objStr = new Buffer(JSON.stringify(obj), 'ascii'); new Buffer(objStr, 'base64').toString('ascii') !== objStr 

I'm trying to keep this as simple as possible.

How can I base-64 encode JSON and safely decode it back to its original value?

Answer 1

From String to Base-64

var obj = {a: 'a', b: 'b'}; var encoded = btoa(JSON.stringify(obj)) 

To decode back to actual

var actual = JSON.parse(atob(encoded))
