This plugin sets user cookie when user is logged in. 
You can use cookie as data store, 
so you can use it as UI resource.
<h4>Visibility</h4>
This plugin adds class to <code>html</code> element.
<ul>
<li><code>ct-logged-in</code> The current user is logged in.</li>
<li><code>ct-not-logged-in</code> The current user is anonymous.</li>
</ul>
You can control elements visibility with CSS.
<pre>.some-element{
 display: none;
}
.ct-logged-in .some-element{
 display: block;
}</pre>
<h4>From JavaScript</h4>
You can use Global Object <code>CookieTasting</code> for utility.
<ul>
<li><code>CookieTasting.userName()</code> Returns user name. If not logged in, returns ‘Guest’.</li>
<li><code>CookieTasting.lastUpdated()</code> Returns timestamp of last log in check. If this equals 0, it means that user is anonymous.</li>
</ul>
Besides that, this plugin checks periodically log-in status. 
You can handle it with jQuery.
<pre>jQuery( document ).on( 'cookie.tasting', function( event, response ) {
 if ( response.login ) {
 // User is logged in.
 // If you use React...
 setAttributes({ name: CookieTasting.userName() })
 } else {
 // User is not logged in.
 }
} );</pre>
If you use react or something, updated the status with <code>setState()</code>.
<h4>Check Before Action</h4>
If you manage cached WordPress and customizing your own theme, 
It’s a good idea to implement dynamic UI components with JavaScript.
You can check user’s credential just before important actions.
<pre>// Click action for button.
$('.read-more').click( function( e ) {
 e.preventDefault();
 // Check cookie before do something.
 CookieTasting.testBefore().then( function( response ) {
 // Now user has fresh information.
 // Load premium contents.
 loadPremiumContents();
 }).catch( function( response ) {
 // This user is not logged in.
 // Redirect them to login page.
 window.locaion.href = '/wp-login.php';
 } );
} );</pre>
Plese remember adding dependency for <code>cookie-tasting-heartbeat</code> to your script.
<h4>Handle UUID</h4>
By default, this plugin set UUID for each user. This will be…
<ul>
<li>Unique for each logged in user and will be saved as user_meta.</li>
<li>Also kept for anonymous user.</li>
</ul>
So you can use it for Google Analytic’s <a href="https://support.google.com/analytics/answer/3123662" rel="nofollow ugc">User ID View</a>.
<pre>const uuid = CookieTasting.get( 'uuid' );
// For Google Analytics.
ga( 'set', "userId", uid );</pre>

nice idea !!!

Detect user login only with cookie. The best helper for cached WordPress sites.
