Hive Programming with NodeJS

Over the years, I've written tons of scripts using NodeJS, but today things changed.

When I use the @hiveio/hive-js library, it's totally broken. I assume this is deprecated and no longer used.

Fortunately, I found the @hiveio/dhive library which does seem to be working. Almost.

I'm trying to transfer some HIVE using the client.broadcast.transfer function, but it returns, "key.sign is not a function"

In general, does the dhive library work? More specifically, how can I transfer HIVE using this code?
