What you have mentioned is the only possible workaround as of now.
Currently, there is not such functionality which can help you to publish all the chapters of the book in single click.

Bah! That sucks. Thanks for taking the time to answer!
Major features don't spring full grown. It was only introduced as an experimental technology in June 2015, about six months ago. There were major upgrades in the August and November releases.
If you make a good case for your workflow in the feature request form, it will make it a higher priority for the InDesign team.
I'm aware it's new and lacking features. I've submitted a feature request.
If this was known a year ago, why so slow in improving the product to allow group INDB online publishing?
Because Publish Online is hosted on the Adobe servers, they can count how many people use the product.
If millions, and millions of books were being created for PubOnline, Adobe would be able to know what features are needed.
I don't follow your logic. If you cannot publish books online currently, how would Adobe know whether or not that feature was needed? Right now, if I use ID CC to create a book, and publish to PDF (which is our current option), that's all they know, if that. You can't know, or correspond to that which you do not know. Does that make sense?
I can think of two reasons why the engineers have not implemented that feature:
(1) What Sandee said, but what I think she implies is that most people creating Publish Online documents are using them for shorter documents not long documents. Many people create multiple-hundred-page documents as a single file, and if there were a demand for long documents it would show in the statistics.
(2) Even more important, I think there are server issues in uploading and downloading large documents. Often they are "heavy" with images and/or videos. If you look at the recently posted list of "Troubleshooting Publish Online errors," you'll see three of them referring to "File size too large":
The point is, if Adobe allowed users to host their own content in the first place, rather than the cloud, AND fully implemented their upgrade (i.e., allowed online publishing of books which is one sweet feature of ID) we wouldn't be having this discussion. Not trying to be difficult,but if I don't find a workable html5 solution, I'm dead in the water.
