Page History

...

The SPA front-end helper libraries provide APIs through which you can stay informed about the status of the current renderer context of an SPA page. The status can be that your SPA page is running in:

• A developer mode.
• The page editor of the Pages editorapp.
• The preview mode of the Pages page editor.

Being aware of the current renderer context can be useful if you need to hit different URLs for content, do rendering or other things conditionally. The status information is retrievable in the in both frameworks integrating SPA development in Magnolia – Angular and React frameworks.

In Angular

In the Angular framework, If you call the isDevMode() function, which is part of the @angular/core library, and the developer mode is enabled, you can see the status as a  a comment in the DOM element.

To find out in Angular whether your SPA page is running in the Pages page editor or in its page preview mode, inject the RendererContextService from the @magnolia/angular-renderer. You can then call the following functions to get the status:

• inEditor()
• inEditorPreview()

In React

To retrieve the status in React, make sure that you import {RendererContext} from the @magnolia/react-renderer, and that the class of YourComponent extends the React.Component.
