To anyone stumbling across this post and trying the above code. Make sure you give enough time for the posts to be pulled. I kept thinking it wasn't working when it was actually still loading them all.

You can also get the x-wp-totalpages by making a HEAD request for the posts URL (/wp-json/wp/v2/posts/). This will return all the headers for the request and none of the content. If you need the total number of posts, there's another header you can get, x-wp-total.

Nice, I've taken a similar approach on posts from multiple sources before. I would just like to point out that this use case is one of the ones where the backend, assuming you control it [ even though it's PHP (gross) ] is probably the better way to go ( primarily because the response time will be much faster than doing multiple queries ). You can use a filter on the rest_[your-post-type]_collections_params like so

function cpt_custom_max_per_page( $params ) {
    if ( isset( $params['per_page'] ) ) {
        $params['per_page']['maximum'] = *value of your choice*;
    }
    return $params;
}

$cpts = ['dancers', 'team_members', 'crew_members', 'locations', 'cats', 'pages'];

foreach( $cpts as $cpt ){
    $post_params_hook = 'rest_' . $cpt . '_collection_params';
    add_filter( $post_params_hook, 'cpt_custom_max_per_page', 10, 1 );
}

Sure if you wanna do this in react just pop it in a lifecycle hook. Let me know if you have any issues :)

hey thanks for the above code, but I have a doubt. Whenever I am sending the get request, the response that comes back has the required data. But when we look at title and content of each post, it has some pagebuilder in it, any idea how to remove it?

[vc_row type=”full_width_background” full_screen_row_position=”middle” scene_position=”center” text_color=”dark” text_align=”left” top_padding=”5%” bottom_padding=”13%” id=”team” overlay_strength=”0.3″ shape_divider_position=”bottom” bg_image_animation=”none” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_link_target=”_self” column_shadow=”none” column_border_radius=”none” width=”1/1″ tablet_width_inherit=”default” tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid” bg_image_animation=”none”][vc_column_text]

It looks like this.
