Заменить
funtion test1(arr)
на

funtion test1(arr) {
       return arr.reduce((res, item) => {
          if (item.id === objID) {
            res.push(item);
          } else {
          res.push(...test1(item.children));
          }
           return res;
        }, []);       
}

В volt обращение к элементам массива как в PHP
{{ product['name'] }}

Через точку будет обращение к свойству
category.name == $category->name

Конфиги Nginx в OSpanel (OpenServer) настраиваются для каждого домена отдельно.
В папку с доменом поместите файл с конфигами, имеющий название версии Nginx, например, Nginx-1.8_vhost.conf или Nginx-1.10_vhost.

Внутренности моего конфига для root в /public:
