SPA templating API

SPA template annotations endpoint

Magnolia SPA template annotations make content from a front-end project editable in Magnolia. This is achieved by injecting annotations (HTML comments) around components which the Magnolia Page editor transforms into controls for web content editors.

Annotations are created on the server and can be retrieved through a dedicated Template annotation endpoint. The advantage is the server renders everything from the attributes. Before, the annotations were created in Magnolia frontend helpers.

Version 6.2.17 of the Pages module also introduced the site-aware template annotations endpoint (, which is aware of site-defined prototype templates.

Page content for single-page applications is delivered through the Delivery API.

SPA template definitions endpoint

For Single-page applications, we provide a dedicated template definitions endpoint which is used to deliver page, area and component template definitions.

Its implementation class is You don’t need to configure anything in the endpoint.

Example request URL and response for template id mtk:components/textImage:

    "mtk:components/textImage": {
        "dialog": "mtk:components/textImage",
        "templateScript": "/mtk/templates/components/textImage.ftl",
        "name": "textImage",
        "id": "mtk:components/textImage",
        "type": "content",
        "renderType": "freemarker"
