##Node.js server backend

###Description

Node.js server that handels analysis of the data and interactions from the website, and processes the data sent from the android device. Takes android data and stores the data in a MongoDB databse.

###Routes:

GET /api/routes

Returns all the route ids stored in the database. Example Response:

{
  "userRoutes": [
    {
      "_id": "56242dd6b6ca65832a1edb77",
      "id": "56242dd5b6ca65832a1edb76",
      "time": "Sun Oct 18 16:39:49 PDT 2015"
    },
    {
      "_id": "56242ecdb6ca65832a1edb79",
      "id": "56242ecdb6ca65832a1edb78",
      "time": "Sun Oct 18 16:43:38 PDT 2015"
    }
  ]
}

• time: when the route began

    GET /api/route/{route_id}
  

Returns the route information for a given route id. Example Response:

    POST /api/route
  

Takes a JSON object parameter and computes and stores the proper data in the database Example Parameter:

  "rpmTimeStamp": [0, 552, 1231, 3424, 3789, 23123]
  }

• all same as above
• two additional fields rpmData and rpmTime
  • rpmData: array of 0s and 1s, 0 means IR sensor was blocked, 1 means IR was clear (used to compute RPM data in response)
  • rpmTimeStamp: indicates when each 0 or 1 was captured ###Host:

The Backend Server written in node.js is running on azure, while the mognodb database is running on AWS, the Virtual Machines for bit coin mining are also on azure.
