我是 Ts 新手，所以我想知道是否可以將我擁有的所有類匯入到一個 ts 檔案中，然后從那里匯出，所以無論何時我想要任何類，我都可以直接從該檔案中匯入它
import Login from "./Login/login_page";
import MyAccount from "./AccountSettings/myAccount_page";
import Settings from "./AccountSettings/settings_page";
import DataProvider from "../utils/data-provider/data-provider";
export default { Login, MyAccount,Settings, DataProvider};
uj5u.com熱心網友回復：
是的，你可以做到。但是一個檔案中最多可以有一個默認匯出。所以，你可以擁有或不擁有，它是可選的。
所以，例如：
import Login from "./Login/login_page";
import MyAccount from "./AccountSettings/myAccount_page";
import Settings from "./AccountSettings/settings_page";
import DataProvider from "../utils/data-provider/data-provider";
export default DataProvider;
export { MyAccount,Settings, DataProvider} ;
或者
import Login from "./Login/login_page";
import MyAccount from "./AccountSettings/myAccount_page";
import Settings from "./AccountSettings/settings_page";
import DataProvider from "../utils/data-provider/data-provider";
export {DataProvider, MyAccount,Settings, DataProvider} ;
