Next Bus (Google Assistant app)

This is a simple application (azure function app) that contains endpoints that a google assistant application calls to determine what the next bus comes for a stop. It works for two locations, home and work and settings to determine what the stop number and bus code is.

It is hooked up with the google assistant api through dialogflow.
