On Node.js a dashboard template can be loaded and saved back to a file — the basis for server-side template processing.

Load, then save.
var Stimulsoft = require('stimulsoft-dashboards-js');

var report = Stimulsoft.Report.StiReport.createNewDashboard();
report.loadFile("Dashboard.mrt");

report.saveFile("Dashboard2.mrt");

How it works. The template round-trips through the filesystem, so dashboards can be read, modified and re-saved entirely on the server.
