How to get X-WP-TotalPages from getRawEntityRecords?

[zeeene]

Description

Hi there, I'm new to Gutenberg, my apologies for the off-topic.

I found the core-data package is handy for accessing data from the backend, So I'm trying to use getRawEntityRecords for fetching posts and it works out of the box. I checked the documentation but looks like it doesn't provide all the data as REST API. I would really appreciate it if someone can help me to find out these mentioned points below:

• How can I access Response Header? ( I need X-WP-TotalPages to display pagination )
• Is there any option to invalidate the cache of getRawEntityRecords manually?

Hello, there is no high-level API to use at the moment that I would be aware of, but I can share an example in the codebase where a workaround exists:

gutenberg/packages/block-library/src/comment-template/hooks.js

Lines 105 to 119 in cb63e4e

	apiFetch( {
	path: addQueryArgs( '/wp/v2/comments', {
	...queryArgs,
	post: postId,
	per_page: perPage,
	_fields: 'id',
	} ),
	method: 'HEAD',
	parse: false,
	} ).then( ( res ) => {
	setDefaultPages( {
	...defaultPages,
	[ key ]: parseInt( res.headers.get( 'X-WP-TotalPages' ) ),
	} );
	} );

@adamziel, it's something that would be great to integrate in the @wordpress/core-data package.

I think this was resolved via #55164.

@youknowriad, can you confirm?

👋🏼 doing a sweep of high priority issues to keep the label relevant and actionable. I've removed this label as it's not clear if this is still actionable and it's stalled for quite some time. If the label needs to be added back in, go for it but please add context as to why it's still relevant and relevant to the degree of needing quick mobilization across the project to address.

Yes, this is addressed with the getEntityRecordsTotalPages selector.
