Embedded Responses - MurhafSousli/ngx-wordpress GitHub Wiki

By default WP API doesn't include featured image, categories, tags, author and comments in the post response, it returns only the Id references for these properties, which needs a separate request for each one of them.

Embedded responses are very useful to reduce the amount of HTTP requests. you will get all the properties in one response.

Embedding is triggered by setting _embed: true in args, check Linking and Embedding

It's highly recommended to use it with WpPost class which makes it easy to access these properties
