Overview

Interactor wrapper around Google Routes API v2 to compute trip details.

Inputs via context:

  • origin: { lat:, lng: } | “lat,lng” | [lat, lng]

  • destination: { lat:, lng: } | “lat,lng” | [lat, lng]

  • Optional arrays: waypoints, pickups, dropoffs (same point formats)

  • Optional boolean: optimize (default: true) to let Google reorder waypoints

Outputs via context on success:

  • distance_km (Float)

  • ordered_waypoints (Array<Hash>)

  • ordered_points (Array<Hash>)

  • directions_url (String)

  • estimated_time_minutes (Integer) when optimize is true

On failure, context.fail!(message: …) is called.
