This is one of my favorite things about the Flavour framework: strongly-typed web service calls:

Your single-page app code calls your backend API using strong types. Your code is clean and the framework handles marshaling and unmarshalling JSON.

if you have control over all the consumers of your API, run whatever makes you fast and keeps you safe.

If you want others to play with your API: JSON here we come.
