Making RPC calls to the server

Sooner or later, your widget will need to look up some data from the server. In this recipe, we will add a category booked panel to the category information panel. When the user hovers their cursor over the category color pill element, the booked panel will show the number of booked rooms related to that category color. We will make an RPC call to the server to fetch a book count of the data associated with that particular category.

Getting ready

For this recipe, we will be using the my_hostel module from the previous recipe.
