navya, Credit to volkotech-solutions Feb 09

In Drupal, a node type can be identified with its bundle type, it is possible to get the bundle type as a body class. Check out this snippet to get the solution.

mythemename.theme

<?php
function themename_preprocess_html(&$vars) {
  $current_path = \Drupal::service('path.current')->getPath();
  $internal = \Drupal::service('path_alias.manager')
    ->getAliasByPath($current_path);
  $vars['attributes']['class'][] = str_replace("/", "", $internal);

  $entity = _helper_get_route_entity();
  $entity_type = $entity ? $entity->getEntityTypeId() : 'non-enitity';
  $entity_type_bundle = $entity ? $entity->bundle() : 'non-enitity';

  // Null on system pages.
  $vars['var_entity_type'] = $entity_type;
  // Null on system pages.
  $vars['var_bundle'] = $entity_type;
  $vars['attributes']['class'][] = $entity_type_bundle;
  $vars['attributes']['class'][] = $entity_type;
}

/* function for _heler_get_route_entity. */

function _helper_get_route_entity() {
  $route_match = \Drupal::routeMatch();
  // Entity will be found in the route parameters.
  if (($route = $route_match->getRouteObject()) && ($parameters = $route->getOption('parameters'))) {
    // Determine if the current route represents an entity.
    foreach ($parameters as $name => $options) {
      if (isset($options['type']) && strpos($options['type'], 'entity:') === 0) {
        $entity = $route_match->getParameter($name);
        if ($entity instanceof ContentEntityInterface && $entity->hasLinkTemplate('canonical')) {
          return $entity;
        }

        // Since the entity was found, no need to iterate further.
        return NULL;
      }
    }
  }
}
