Route callbacks

Async-based

Example how to run Express with async routes + wrapper for async functions so you would not have to put route callback code in try/catch block.

One can actually pass it to express as-is, but could also wrap it with dedicated wrapper for easy error handling.

See /async

Generator-based

Implements wrapper for generator functions; it teaches generators how to yield promises. This way wrapper acting as a coroutine feeds generator with resolved result of yielded promise.
