Very Easy Solution
Just add a hidden field inside the form. An Example
<form id="logout-form" action="/logout" method="POST" style="display: none;">
<input type="hidden" name="_token" :value="csrf">
</form>
Now add csrf
variable inside script at the vue file, like this. (Remember, it must be inside data).
<script>
export default {
data: () => ({
csrf: document.querySelector('meta[name="csrf-token"]').getAttribute('content'),
}),
}
</script>
N.B. You will see a meta tag in your blade.php
file like this.
<!-- CSRF Token -->
<meta name="csrf-token" content="{{ csrf_token() }}">
If there is nothing like this, you need to place it there.
