quick geocoder in D8

geocoder.module

<?php

function geocoder_entity_presave(Drupal\Core\Entity\EntityInterface $entity) {

  if ($entity->getEntityTypeId() == 'node' && $entity->bundle() == 'distributor'){
    $street = $entity->get('field_street')->getString();
    $city = $entity->get('field_city')->getString();
    $country = $entity->get('field_country')->getString();
    $adress = sprintf('%s, %s, %s',$street,$city,$country);
    $geocode = new Geocode();
    $result = $geocode->get($adress);
    $lat = $result->getLatitude();
    $long = $result->getLongitude();
    $entity->set('field_latitude',$lat);
    $entity->set('field_longitude',$long);
  }
}

And yes it could be a lot cleaner without using transporter variables for lat and long etc.
