Single page applications (SPAs) can offer compelling experiences for website users. Developers want to be able to build sites using SPA frameworks and authors want to seamlessly edit content within AEM for a site built using such frameworks.
The SPA Editor offers a comprehensive solution for supporting SPAs within AEM. This page gives an overview of how SPA support is structured in AEM, how the SPA Editor works, and how the SPA framework and AEM keep in synch.
Sites built using common SPA frameworks such as React and Angular load their content via dynamic JSON and do not provide the HTML structure that is necessary for the AEM Page Editor to be able to place edit controls.
To enable the editing of SPAs within AEM, a mapping between the JSON output of the SPA and the content model in the AEM repository is needed to save changes to the content.
SPA support in AEM introduces a thin JS layer that interacts with the SPA JS code when loaded in the Page Editor with which events can be sent and the location for the edit controls can be activated to allow in-context editing. This feature builds upon the Content Services API Endpoint concept since the content from the SPA needs to be loaded via Content Services.
Note: The Single-Page Application (SPA) Editor feature requires AEM 6.4 service pack 2 or newer.
The SPA Editor is the recommended solution for projects that require SPA framework based client-side rendering (e.g. React or Angular).
