You seem to be trying to reload the entire page with paginated data - that's a really bad practice. In the long run, you'll end up with slower pages that way.
You would be better off having a separate endpoint for your AJAX that outputs a JSON array of HTML strings, one for each post. This is still slower than using a 2-tier solution like Codeigniter and React, but it's certainly faster than constantly rerendering the entire UI.
I got a working solution:
(function($) {
var currentPage = 2,
maxPage = $('#postsContainer').data('max-page'),
posts = null;
$('.pagination').hide();
$(window).scroll(function() {
var toBottom = $(window).scrollTop() >= $(document).height() - $(window).height() - 25;
if (toBottom && currentPage <= maxPage) {
loadMore();
}
});
function loadMore() {
$.ajax({
url: baseUrl + '?page=' + currentPage,
type: 'GET',
beforeSend: function() {
if (typeof posts != 'undefined') {
$('.loader').show();
}
}
})
.done(function(data) {
$('.loader').hide();
posts = $(data).find('#postsContainer').html();
if (typeof posts != 'undefined') {
$('#postsContainer').append(posts);
currentPage = currentPage + 1;
if (currentPage > maxPage) {
$('#postsContainer').append('<p class="text-center text-muted">No more posts to load</p>');
}
}
});
}
})(jQuery);

React is currently the leader in JavaScript UI frameworks. First, the Facebook developers started working on this to make their job easier. An app called Facebook Ads grew very quickly, which meant complex management and support. As a result, the team began to create a structure that would help them with efficiency. They had an early prototype before 2011, and two years later, the framework was open source and available to the public. It is currently used by many business giants: AirBNB, PayPal, Netflix, etc.
