How do you debug a page in a custom module. or more to the point. How do you debug whether the xml is rending the correct page content.

I am trying to create a page in my custom module, I am able to create the page but its content is blank.

I believe that the problem relates to the xml because if I do a vardump on the controller it renders an output. this means that the problem relates to the xml output.

below are my files-- I would really appriate any advice on how I can go out debugging the problem.

=> Block :

namespace Lsg\Authunpw\Block;

class PostList extends \Magento\Framework\View\Element\Template

    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,

        array $data = []
    ) {
        parent::__construct($context, $data);
    //    $this->_postCollectionFactory = $postCollectionFactory;

    public function getIdentities()
        return [\Lsg\Authunpw\Model\Customer::CACHE_TAG . '_' . 'list'];


Fronend xml :


<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    <router id="standard">
        <route id="auths" frontName="auths">
            <module name="Lsg_Authunpw" />

Frontend view :


<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column"
        <referenceContainer name="content">
            <block class="Lsg\Authunpw\Block\PostList" name="auths.list" template="Lsg_Authunpw::list.phtml" />
