REST is a powerful architecture because of its loose coupling design that facilitates a high level of interoperability. However, even the dissertation that defines REST states that one of the trade-offs of REST is that it “degrades efficiency, since information is transferred in a standardized form rather than one which is specific to an application’s needs”. That is, you might be able to achieve more efficient operation using a mechanism that goes beyond REST’s uniform interface, that is more specific to your application. This comes at the price of a loss of interoperability and should only be used if necessary, but with this in mind, let’s look at a good way to use RPCs that integrate with Dojo’s REST module, the JsonRestStore. This approach builds on the REST architecture, while allowing exceptions as needed.
