- Once created, the type of a named attribute cannot be changed. Subsequent calls to **Set** must set a value of same type.
- LocalStorage provides page-level storage. The [GetShared](../reference/arkui-ts/ts-state-management.md#getshared9) API can only obtain the LocalStorage instance transferred through [windowStage.loadContent](../reference/apis/js-apis-window.md#loadcontent9) in the current stage.

### Sharing a LocalStorage Instance from UIAbility to One or More Pages
### Example of Sharing a LocalStorage Instance from UIAbility to One or More Pages
In the preceding examples, the LocalStorage instance is shared only in an \@Entry decorated component and its owning child component (a page). To enable a LocalStorage instance to be shared across pages, you can create a LocalStorage instance in the owning UIAbility and call windowStage.[loadContent](../reference/apis/js-apis-window.md#loadcontent9).

The **Router** module provides two redirection modes: [router.pushUrl()](../reference/apis/js-apis-router.md#routerpushurl9) and [router.replaceUrl()](../reference/apis/js-apis-router.md#routerreplaceurl9). The two modes determine whether the target page will replace the current page.
The **Router** module provides two redirection modes: [router.pushUrl()](../reference/apis/js-apis-router.md#routerpushurl9) and [router.replaceUrl()](../reference/apis/js-apis-router.md#routerreplaceurl9). Whether the target page will replace the current page depends on the mode used.
- **router.pushUrl()**: The target page does not replace the current page. Instead, it is pushed into the [page stack](../application-models/page-mission-stack.md). In this way, the state of the current page can be retained, and users can return to the current page by pressing the back button or calling the [router.back()](../reference/apis/js-apis-router.md#routerback) API.
- **router.pushUrl()**: The target page is pushed into the [page stack](../application-models/page-mission-stack.md) and does not replace the current page. In this mode, the state of the current page is retained, and users can return to the current page by pressing the back button or calling the [router.back()](../reference/apis/js-apis-router.md#routerback) API.
- **router.replaceUrl()**: The target page replaces the current page and destroys the current page. In this way, the resources of the current page can be released, and users cannot return to the current page.
- **router.replaceUrl()**: The target page replaces and destroys the current page. In this mode, the resources of the current page can be released, and users cannot return to the current page.

The **Router** module also provides two instance modes: **Standard** and **Single**. The two modes determine whether the target URL corresponds to multiple instances.
The **Router** module also provides two instance modes: **Standard** and **Single**. Depending on the mode, the target URL is mapped to one or more instances.
- **Standard**: standard instance mode, which is the default instance mode. Each time this API is called, a target page is created and pushed to the top of the stack.
- **Standard**: multi-instance mode. It is the default instance mode. In this mode, the target page is added to the top of the page stack, regardless of whether a page with the same URL exists in the stack.
- **Single**: singleton mode. If the URL of the target page already exists in the page stack, the page with the same URL closest to the top of the stack is moved to the top of the stack and reloaded. If the URL of the target page does not exist in the page stack, the page is redirected in standard mode.
- **Single**: singleton mode. In this mode, if the URL of the target page already exists in the page stack, the page closest to the top of the stack with the same URL is moved to the top of the stack and becomes the new page. If the URL of the target page does not exist in the page stack, the page is redirected in standard mode.

- Scenario 2: There is a login page (**Login**) and a personal center page (**Profile**). After a user successfully logs in from the **Login** page, the **Profile** page is displayed. At the same time, the **Login** page is destroyed, and the application exits when the back button is pressed.

## Page Return
After a user completes an operation on a page, the user usually needs to return to the previous page or a specified page. In this case, the page return function is required. During the return process, the data may need to be transferred to the target page, which requires the data transfer function.
Implement the page return feature so that users can return to the previous page or a specified page. You can pass parameters to the target page during the return process.

## Named Route
To redirect to a [page in a shared package](../quick-start/shared-guide.md), you can use [router.pushNamedRoute()](../reference/apis/js-apis-router.md#routerpushnamedroute10).
Before using the **Router** module, import it first.
```ts
import router from '@ohos.router';
```
In the target page in the [shared package](../quick-start/shared-guide.md), name the [@Entry decorated custom component](../quick-start/arkts-create-custom-components.md#entryoptions10).
```ts
// library/src/main/ets/pages/Index.ets
@Entry({ routeName : 'myPage' })
@Component
struct MyComponent {
}
```
When the configuration is successful, import the named route page to the page from which you want to redirect.
```ts
// entry/src/main/ets/pages/Index.ets
import router from '@ohos.router';
import 'library/src/main/ets/Index.ets' // Import the named route page from the shared package library.
@Entry
@Component
