It's not a client library, actually an official client library for Node.js already exists: https://github.com/google/google-api-nodejs-client

It's just a command line tool that internally uses the official client library.

I guess in general using the web interface is easier, but there are some use cases.

For instance, in our project we inserted an event after each release, until now we did it manually. Using this it can be automated, being included inside our release flow in our Jenkins server.
