A pagination feature is being added to the comments section to group and provide comments data to the client.
The content already had pagination, offering two items per page.
The per-page item count is set by an environment variable in the header.
A header x-total-count indicates the total content count, which is necessary for the client to implement pagination.
Pagination is done using a middleware, which is being modified to support a parameter for the number of items per page.
The pagination middleware is updated to accept items per page as a number parameter, replacing the hardcoded limit.
The post per page configuration import at the top of the file is removed as it's no longer needed.
The post per page variable from the app config is adjusted to ensure it is a number, not a string.
The corrected pagination setting is then used in the post router.
An HTTP client is used to test the pagination feature, confirming that it provides paged content data and displays the correct total count of content items.
