Question

How do I create a base64 JSON encoded strings in nodejs?

I tried this and it didn't work.

var buff = new Buffer({"hello":"world"}).toString("base64");

Is this it?

var buff = new Buffer(JSON.stringify({"hello":"world"})).toString("base64");

var buff = new Buffer(JSON.stringify({"hello":"world"})).toString("base64");

Answer 2

To complete @ladenedge's comment for clarity reasons:

var buff = Buffer.from(JSON.stringify({"hello":"world"})).toString("base64")
