rest-sugar makes it easy to implement yummy REST APIs
The whole point of this library is to make it easy to implement simple yet powerful REST APIs. There are a few extension points you can hook into. mongoose-sugar complements this particular library very well. It is possible to implement similar solutions for other backends too.
Even though the library has been designed based on Express, it might be possible to make it work with other similar libraries too given they use Express conventions. This might take some kind of an adapter.
See demo.js to see how the architecture works out. Note that as it does not use mongoose-sugar it is a bit lengthy. It should give you some idea how to implement components that fit the whole, though.
