Hi,

I am currently working on a project where I serialize JSON objects using the php library msgpack-php, but when I try to deserialize these objects using the javascript library msgpack-javascript, my integers are truncated.

PHP :

$data = [ '7355750935770677725' => "test", ]; $msg = msgpack_pack($data); ...

JS :

import { decode } from '@msgpack/msgpack'; const decoded = decode(entry); console.log(decoded)

Result :

{ '7355750935770677000': 'test' } 

As you can see the last three digits of my integer are set to 0.

This seems to be an interoperability problem between the php library and Node.js
