Loading a Report from the Server-Side
Наши примеры проектов и шаблоны отчётов помогут Вам разобраться в основах работы с нашими продуктами.A common pattern is to render a report on the Node.js server and send the finished document to a viewer running in the browser.
Loading the template. Create the report, load the template from the demonstrated source, and pass it to the next rendering, viewing, or export step.
The server renders the report and returns it with

console.log("Static file server running at http://localhost:" + 8888 + "/\nCTRL + C to shutdown");
//The HTTP server run on port 8888
http.createServer(accept).listen(8888);The server renders the report and returns it with
saveDocumentToJsonString; the browser viewer then loads that JSON and displays it. This offloads the rendering work to the server while the client only shows the result.
