@shilman want me to add this to telejson? I think it can just be a toString and then put it back into a BigInt on parse

@phated sure! 🙏

The referenced telejson merge was shipped in version 5.3.0 and storybook comes with 5.3.3, I'm still experiencing this issue.

Most of my components have bigint in them, so I can't use Storybook until this is fixed :/

I don't know anything about storybook dev, but from a quick look this issue stems from the stringify here

JSON.stringify(value, (key, value) => 
  typeof value === "bigint" ? value.toString() + "n" : value
, 2);

which stops everything from crashing

I imagine the parse in the same file as above

needs updating to

JSON.parse(raw, (key, value) => {
  if (typeof value === "string" && /^\d+n$/.test(value)) {
    return BigInt(value.substr(0, value.length - 1));
  }
  return value;
});

There are a few parses and stringifys in storybook, but not too many :)

unfortunately, the REJT (React Editable JSON tree) doesn't render the bigints - it looks like REJT limits it's datatypes and, instead of attempting to .toString() the value, just defaults to rendering nothing.

+1 to the json-bigint recommendation
