How to list all titles of posts on a specific page?

Paste this into your page template. It will output a list of all posts (without pagination).

<?php
// the query
$all_posts = new WP_Query( array( 'post_type' => 'post', 'post_status' => 'publish', 'posts_per_page' => -1 ) );

if ( $all_posts->have_posts() ) :
?>

  <ul>
    <?php while ( $all_posts->have_posts() ) : $all_posts->the_post(); ?>
      <li><a href="https://wordpress.stackexchange.com/questions/240419/<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
    <?php endwhile; ?>
  </ul>

<?php else : ?>
  <p><?php _e( 'Sorry, no posts were found.' ); ?></p>
<?php endif; ?>

<?php wp_reset_postdata(); ?>
