Thank you for raising this issue. We have recently updated the links in npmjs package’s readme, so they should now be accessible.
Regarding the use of the “_public” flag, it is added by the client generator due to the reserved keyword “public”. While it is common convention to use underscores to indicate private variables, we always recommend to follow the indicated format in our documentation. We apologize for any confusion this may have caused.
another question regarding private videos, how do I get the token and then session token described here Create, deliver, and manage private videos with your nodejs sdk?
