How to check if post title already exists?

I followed this accepted answer and read the docs, finally I tried to apply the logic using ajax:

On frontEnd:

var ajax_url = '<?php echo admin_url( 'admin-ajax.php' ); ?>';
$("#publish").on("click", function() {
  $.ajax({
    url : ajax_url,
    type: 'post',
    data: { 
      action: 'data_Publish', portfolioTitle: $("#portfolioTitle").val(), idsInput: $("#idsInput").val()
    },
    success: function(data) {
      console.log(data);
      $("#titleSaveModal .modal-body").html("<p>Pubblicato</p>");
    }
  });
});

On function.php

function data_Publish() {
  $post_title = $_POST['portfolioTitle'];
  $post = array(
    'post_title'    => $post_title,
    'post_status'   => 'publish',
    'post_type'   => 'page',
    'page_template'  => 'portoflio.php'
  );
  if ( get_page_by_title( $post_title ) === null ) {
    echo "Already exists!";
  } else {
    $post_id = wp_insert_post( $post );
    add_post_meta($post_id, 'portfolio-ids', $_POST['idsInput'], true);
  }
  wp_die();
}
add_action('wp_ajax_data_Publish', 'data_Publish');

But even if I give a same title, it will always publish a new post, meaning it is not finding out that title already exists, what am I doing wrong?

The condition is backwards, get_page_by_title( $post_title ) === null means it doesn't exist, you just have to swap the then and else code blocks.

if ( get_page_by_title( $post_title ) === null ) {
  $post_id = wp_insert_post( $post );
  add_post_meta($post_id, 'portfolio-ids', $_POST['idsInput'], true);
} else {
  echo "Already exists!";
}
