This plugin will add separate WordPress REST API (v2) endpoint, with all relations between existing post types and attached to them terms (taxonomies). 
It is very useful when you need to create some filters, when you want to know what taxonomies are attached to the current post type.
For example what can you get, using <code>wp-json/wp/v2/post-type-taxonomies</code> request (empty results not included):
<pre><code>{
 post: [
 "category",
 "post_tag",
 "post_format"
 ],
 portfolio: [
 "technologies",
 "clients",
 "work_types"
 ]
}
</code></pre>
