What’s hook_node_view alternative in Drupal 8?

I am using Drupal 8 Beta 14 and I want to edit the node object in teaser view mode. As hook_node_view is removed in Drupal 8. What’s the alternative hook or some other way that I can use to edit the node? Is it hook_ENTITY_TYPE_view or hook_entity_view or some other thing?

Thank you.
