What's the easiest way to fetch the number of ments and the number of likes a post has?

I don't see any usefull field when fetching a post (with a request like https://site/wp-json/wp/v2/posts?after=2018-07-21T15:05:44.000Z)

I'm currently using javascript issuing direct requests with axios.

If you have edit access to the code of the site your are requesting, you could add the field to the responses provided by the JSON API.

Something like this:

add_action( 'rest_api_init', function() {
    \register_rest_field( 'post', 'ment_count', [
        'get_callback' => function ( $post ) {
            return (int) wp_count_ments( $post['id'] )->approved;
        },
        'schema'       => [
            'description' => 'List number of ments attached to this post.',
            'type'        => 'integer',
        ],
    ] );
});

If you don't have access to the site you are requesting, you can have the ments added to the response by send ?_embed=true at the end of the URL and simply count the replies.

Something like this:

const {data} = await Axios.get( 'https://site/wp-json/wp/v2/posts?after=2018-07-21T15:05:44.000Z&_embed=true' );

data.map( post => {
    console.log( post._embedded.replies.length );
});

Not so much a JavaScript related question but here's an answer anyway.

The easiest way to get the number of ments for any post aside from adding a custom endpoint to the REST API is to use the ments endpoint (https://site/wp-json/wp/v2/ments?post=1234&per_page=1) and use the response's X-WP-Total header.
