You can set a X-CSRF-TOKEN header to the Laravel csrf token on the $http module.
https://docs.angularjs.org/api/ng/service/$http
let token = document.head.querySelector('meta[name="csrf-token"]');
$httpProvider.defaults.headers.common['X-CSRF-TOKEN'] = token;
Basically the same thing that is done for axios in the bootstrap.js in Laravel.
