Additional Context

For now you'll need to use strings and a bigdec/int library module to handle numbers beyond the normal range of the Javascript engine. In the near future I believe we'll enable the big number extension of quickjs, though you will then have to configure your couchdb nodes to run with that engine.

We have enabled bigint support for the quickjs engine at least. The json encoding is not automatic, bigints can be parsed from strings, manipulated in js, then have to be serialized back to strings before emitting. It's kind of a minimal standard-compliant bigint support. This should be part of the upcoming 3.5.0 release so closing the issue for now.
