API

const TallyGo = require('tallygo-js');
const tallygo = TallyGo.configure({apiKey: '<YOUR API KEY>'})

const requestOptions = {
  startPoint: [34.76151710, -112.05714849],
  endPoint: [34.76260434, -112.01666952],
  time: '2018-11-13T01:31:51-0800'
  course: 0,
  speed: 0,
  requestType: 'DepartureTime',
  useCarpoolLanes: false,
  useExpressLanes: false
}

tallygo.request.get(requestOptions).then(
  function(json) { console.log(json) }
)

The JSON response object has the following structure:

• distance (number) - the total travel distance in miles
• duration (number) - estimated travel time in minutes. Will always be a sum of points.t
• originalStartNode - start node ID of the edge that start point lays on
• originalEndNode - end node ID of the edge that end point lays on
• routeSegments ([RouteSegment]) - 1 or more legs for this route.
  • distance (number) - the total travel distance in miles for this leg
  • duration (number) - estimated travel time in minutes for this leg.
  • originalStartNode - start node ID of the edge that start point lays on, for this leg
  • originalEndNode - end node ID of the edge that end point lays on, for this leg
  • points ([Point]) - every point in the route in sequence
    • lat (number) - latitude
    • lon (number) - longitude
    • t (number) - estimated travel time in seconds from the previous point
    • d (number) - the distance in miles from the previous point
    • say optional ([string]) - the instructions to be spoken at or near this point
    • notify optional (string) - the out-of-app notification to be displayed at or near this point
    • turn optional (Turn) - the turn at this point
      • dir (TurnDirection enum) - the direction of turn (or destination, when applicable)
      • st (Street) - the street being turned onto
        • name (string) - The name of this street
        • func ({highway, localhighway, arterial, localarterial, residential, service}) - the function of the street
        • connection optional ({origin, offramp, onramp, interchange, connector, destination})
        • dir optional ({north, south, east, west}) - the directionality of the street
        • hwy optional (HighwayId) - more information about this street if it is a highway
          • number (number) - the number of the highway
          • type (string) - ({CA, US, I, Hwy, CR, SR}) - the type of highway
      • instruct optional (string) - The text describing the turn instruction for the turn-by-turn list
    • node optional (number) - OSM node id associated with the point
    • edge optional (number) - OSM way id which starts with this point

The library provides a convenience class for working with Route objects.

tallygo.request.get(requestOptions).then(
  function(json) {
  let route = tallygo.newRoute(json)
  // do something with the Route object
  }
)
