[erlang-questions] Best way to send JSON from erlang to the browser and back

[Andrew Berman]

Joe,

I know you had another email related to this, but I'm wondering why you
couldn't use BERT and on the Erlang side, base64 encode it (so Jquery AJAX
can work with it), then base64 decode it in the JavaScript and use BERT-JS (
https://github.com/rustyio/BERT-JS) and the same thing going the other way.
 This should ensure that things never change between
serialization/deserialization.

Just a thought....

Andrew
