 Expose the old slugs for all posts including custom post types in the REST
 API.

 For example, when building a React-powered app using the WordPress REST
 API the old slugs are required so that users can be automatically
 redirected if they clicked on an old link.

 To expose the old slugs I created a small plugin (see below):
 {{{#!php
 <?php
 add_action( 'rest_api_init', 'expose_old_slugs_in_api' );

 function expose_old_slugs_in_api() {
   $post_types = get_post_types( array( 'show_in_rest' => true,
 'show_in_nav_menus' => true ) ) ;

   $args = array(
     'get_callback' => 'get_old_slugs_for_api',
     'schema' => null
   );

   foreach ($post_types as $type) {
     register_rest_field( $type, 'old_slugs', $args );
   }
 }

 function get_old_slugs_for_api( $object ) {
   //get the id of the post object array
   $post_id = $object['id'];

   //return the post meta
   return get_post_meta( $post_id, '_wp_old_slug' );
 }
 }}}
