A simple function for Typescript sources to wrap async Express route
npm install async-wrapper-express-ts

Wraps the express route in a function that passes the next method from the route to the promise's catch statement which allows the middleware to catch the exception.
This code was borrowed from the StrongLoop blog post on handling async/await routes in express. This npm module allows you to use this solution in the typescript sources.
``bashWith npm
npm install --save async-wrapper-express-ts
Usage
`ts
import asyncWrapper from 'asyncWrapper'
...
app.get('/foo', asyncWrapper(someAsyncRouteFunction))
``
