This example illustrates loading of the dashboard that uses json database from some web-server and accessible only by suppliing custom HTTP header. That dashboard is rendered and result is stored to the pdf-file.

Installation and running
Use npm to install requred modules:

$ npm install

Run Sample:

$ npm start

Step by step
Stimulsoft Dashboards.JS module loading:

var Stimulsoft = require('stimulsoft-dashboards-js');

Creating new dashboard:

var report = Stimulsoft.Report.StiReport.createNewDashboard();

Add onBeginProcessData event handler and set necessary headers:

report.onBeginProcessData = function (args) {
    if (
        args.database === "JSON" && 
        args.command === "GetData" && 
        args.pathData && args.pathData.endsWith("/ProtectedDemo.json")
    ) {
        // Add custom header to pass through server protection
        args.headers.push({key: "X-Auth-Token", value: "*YOUR TOKEN*"});
    }
};

Loading sample report template:

report.loadFile("DBSsimp.mrt");

Export to PDF:

report.exportDocumentAsync((pdfData) => {
    // Converting Array into buffer
    var buffer = Buffer.from(pdfData);

    // File System module
    var fs = require('fs');

    // Saving string with rendered dashboard in PDF into a file
    fs.writeFileSync('./Dashboard.pdf', buffer);
}, Stimulsoft.Report.StiExportFormat.Pdf);
