At this point, we have two modules completely refactored, so it's a good time to take the app for a test drive and check out how the newly added query support works. To get the app up-and-running, first build it via docker-build.sh and then start it up via launch.sh. You should create a new BookstoreUser and then a new book via the REST API, being sure to add an inventory to it. Refer to the Interacting with the Book endpoint section from Chapter 1, Building a Better Reactive App, if you need help remembering the endpoint calls to make.
