Внедрение Guards NestJS. Аутентификация и авторизация на основе ролей

const ROLE = {
  ADMIN: 'admin',
  USER: 'user',
  SUPER_ADMIN: 'super-admin'
} as const;


const ROLE_INDEX = {
  [ROLE.USER]: 0,
  [ROLE.ADMIN]: 1,
  [ROLE.SUPER_ADMIN]: 2
} as const;

const requiredRole = ROLE.ADMIN;
const currentRole = ROLE.USER;

const roleSupported = ROLE_INDEX[currentRole] >= ROLE_INDEX[requiredRole];
