You have to add thex-data attribute to an Alpine.js component even without any data definitions, otherwise Alpine.js will ignore it.
<header x-data="{}" x-ref="header">
header code here
</header>
Also add the defer attribute to Alpine.js <script> tag or move it t the end of <body> to solve the warning message.
