Editor context of an SPA page
The SPA SPA front-end helper libraries provide APIs through which you can stay informed about the status of the current editor 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 app.
-
The preview mode of the page editor.
Being aware of the current editor 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 all frameworks integrating SPA development in Magnolia: React, Angular, and Vue.
Magnolia Context object
Version 1.3.0 of the SPA front-end helper libraries introduces the magnoliaContext object, which standardizes usage of the helper libraries.
You can use not only absolute but also relative paths as requestUrl to build the Magnolia Context object.

Editor/preview check
To find out whether your SPA page is running in the page editor or in its page preview mode, inject
-
EditorContextServicefrom the@magnolia/angular-editor, -
EditorContextHelperfrom the@magnolia/react-editor, -
EditorContextHelperfrom the@magnolia/vue-editor,
depending on which framework you are using, Angular, ReactJS or Vue. respectively.
global.mgnlInPageEditor is deprecated and not necessary.

Get the context object by calling:
const magnoliaContext = EditorContextHelper.getMagnoliaContext(fullURL, pageRootPath, languages);
You can then use the following properties to get the status:
-
magnoliaContext.isMagnolia -
magnoliaContext.isMagnoliaEdit -
magnoliaContext.isMagnoliaPreview

Developer mode check (Angular)
In the Angular framework, the status of an SPA page being in the developer mode can be checked by calling the isDevMode() function, which is part of the @angular/core library.
Developer mode check (ReactJS)
To retrieve the status of the developer mode in ReactJS, make sure that you import {EditorContext} from the @magnolia/react-editor, and that the class of YourComponent extends the React.Component.
After assigning static contextType = EditorContext you can call the following functions to get the status:
-
this.context.isDevMode
