Registering a Data from Code when Rendering a Report on the Server-Side
Наши примеры проектов и шаблоны отчётов помогут Вам разобраться в основах работы с нашими продуктами.When rendering server-side, data can be registered through the onBeforeRender event, which runs in the Node.js engine.
Preparing the data. Read or create the data source, register it in the report dictionary, synchronize the schema, and render with the supplied records.

The
onBeforeRender script runs inside the server-side engine just before rendering, letting you attach data to a headless render exactly as you would in the browser.
