How can I use laravel partial view by angular js in templateURL

First you must define a route in laravel

Route::get('comment-form', function() {
    return view('comments.comment-form');
});

Then you can use it in AngularJS

var commentsApp = angular.module('CommentApp', []);

commentsApp.directive('commentForm', function() {
    return {
        restrict: 'EA',
        replace: 'true',
        templateURL: 'comment-form'
    }
});
