3.6.7: Fix for "Do not know how to serialize a BigInt"

[JoakimCh]

When I'm using BigInts in my code I get this error message Do not know how to serialize a BigInt.

I know how to fix this problem, but do not ask me to create a pull request (since I do not have any knowledge of how to do that or any interest).

To fix it replace line 142 in the file lib/jsdoc/util/dumper.js with:

result.push( JSON.stringify(walker.walk(arg), (key, value) => typeof value == 'bigint' ? value.toString() : value, 4) );

I have also run into this issue

JSDoc 3.6.10

1. Open /node_modules/jsdoc/lib/jsdoc/src/astnode.js
2. Add function

function strReplacer (k, v) {
  if (typeof v === 'bigint') {
    return v.toString() + 'n'
  }
  return v
}

3. Replace all JSON.stringify(tempObject) to JSON.stringify(tempObject, strReplacer)

should jsdoc add that by default? manually editing a lib isn't quite right

Alternative solution without source patching: use .js config with this code:

// BigInt JSON serialization.
BigInt.prototype.toJSON = function() {
	return this.toString() + 'n';
}

Still monkey patch too 😅 .
