Overview

uberNow is a small web app which takes four inputs from the user and notifies the user via email as to when to book an Uber.

All you(the user) have to do is give the 4 required inputs and submit the request. The app will take care of the rest.

The inputs are:

• 1. source
• 2. destination
• 3. email address
• 4. time to reach destination

It uses Tornado as the application server. The web app is created using the sockjs protocol. SockJS is implemented in many languages, primarily in Javascript to talk to the servers in real time, which tries to create a duplex bi-directional connection between the Client(browser) and the Server. Ther server should also implement the sockjs protocol. Thus using the sockjs-tornado library which exposes the sockjs protocol in Tornado server.

It first tries to create a Websocket connection, and if it fails then it fallbacks to other transport mechanisms, such as Ajax, long polling, etc. After the connection is established, the tornado server (sockjs-tornado) calls Uber Apis and Google Maps Apis to process the requests.
