How Do I Redirect WWW to Non WWW in Shopify?

It’s really easy to redirect www to non www in Shopify. You just need to add a code snippet to your theme’s functions.php file. Here’s the code snippet:

function wp_redirect_nonwww(){
if (strpos($_SERVER['HTTP_HOST'], 'www.') !== false) {
$host = str_replace('www. 

', '', $_SERVER['HTTP_HOST']);
header('Location: http://' . $host . $_SERVER['REQUEST_URI']);
exit;
}
}
add_action('init', 'wp_redirect_nonwww');

Once you add that code snippet, www will be redirected to non www automatically.
