It is on azure as web app. Could it be iisnode problem?

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<handlers>
<add name="iisnode" path="app.js" verb="" modules="iisnode"/>
</handlers>
<rewrite>
<rules>
<rule name="DynamicContent">
<match url="/" />
<action type="Rewrite" url="app.js"/>
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>

Sorry, not sure how to format code here x_ x

Is there any config option to keep it alive while using jsreport-core?

this is my config as of now

const config = {
phantom: {
strategy: "phantom-server"
},
templatingEngines: {
numberOfWorkers: 1,
strategy: "in-process"
},
licenseKey: process.env.JSREPORT_LICENSE
};

but it keeps falling asleep after like an hours or so and the initial request then takes quite long

Thanks "face palm"

var jsreport = require("jsreport-core)(CONFIG);

Can I add license key inside of the config object? If yes, what is the property called and where is it placed. I tried to look for it in documentation but I failed ._ .

@djapecom You are right, I had older version of node. Now I got a question. I want to use a jsreport-core in my nodejs app. But the only thing that this app wants to do is just take the api request and returns a render pdf as a stream or whatever. I just have a problem with setup.

And I made a small thing like that with express, but the problem that I have when I deployed in on azure windows web app with node >=8.9 is that making request to
the endpoint which takes used the jsreport-core, it hangs up for 2 minutes and then just timesout. I don't know, maybe my setup is wrong or maybe the jsreport core is using some different ports? It works locally, but not on azure.

Here is the code I have used

app.js

var JSREPORT_CONFIG = Object.freeze({
phantom: {
strategy: "phantom-server"
},
templatingEngines: {
numberOfWorkers: 1,
strategy: "http-server",
timeout: 60000
}
});

var jsreport = require('jsreport-core')(JSREPORT_CONFIG);
var express = require('express');
var bodyParser = require("body-parser");
var compression = require('compression');
var helmet = require('helmet');
var cors = require('cors');
var routes = require('./jsreport.pdf.api/routes');

var app = express();
app.use(cors());
app.use(compression());
app.use(helmet());
app.use(bodyParser.json({ limit: '100mb' }));
app.use(bodyParser.urlencoded({ limit: '100mb', extended: true }));
app.use(routes);

var PORT = process.env.PORT || 3000;
app.listen(PORT);

route
router.get("/api/generate", pdf_controller.pdfGetInstance);

and here is the controller
'use strict';

var jsreport = require('jsreport-core')();

jsreport.use(require('jsreport-phantom-pdf')());
jsreport.use(require('jsreport-handlebars')());
jsreport.init();

var ENGINE = "handlebars";
var RECIPE = "phantom-pdf";

exports.pdfInstance = function (req, res) {
var _req$body = req.body,
data = _req$body.data,
template = _req$body.template,
scripts = _req$body.scripts;
var phantom = template.phantom,
helpers = template.helpers,
content = template.content;
var header = phantom.header,
footer = phantom.footer,
headerHeight = phantom.headerHeight,
footerHeight = phantom.footerHeight,
format = phantom.format;

jsreport.render({
    template: {
        content: content,
        engine: ENGINE,
        recipe: RECIPE,
        phantom: {
            header: header,
            footer: footer,
            headerHeight: headerHeight,
            footerHeight: footerHeight,
            format: format
        },
        helpers: helpers
    },
    data: data,
    options: {
        timeout: 60000,
        reportName: "Pdf Document"
    }
})

.then(function (resp) {
    res.send(resp.content);
})

.catch(function (resp) {
    res.send(resp);
});

};

And as said. It works perfectly fine localy. On azure api endpoints other than this one works aswell. But the one with jsreport.render just hangs for 120000ms and timesout. I just want it to finally work :D, bought the license key but cannot make a use of it x_ x

So, I deployed me node express app with jsreport inside but when I try to run the app I get this error

http://prntscr.com/kqwhhe

How can I make jsreport-core run in the production mode? Or something that doesn't break with es6

@jan_blaha

Wops sorry, it actually has await but the StartAsync is called inside a method which is placed in som PdfCreator class.

    public async Task<byte[]> CreatePdfReport(ILocalWebServerReportingService _reportingService, PdfTemplate template, IEnumerable<PdfPart> templateParts, IPdfStateObject stateObject)
    {
        await _reportingService.StartAsync();

        var renderRequest = CreateRenderRequest(template, templateParts, stateObject);
        var report = await _reportingService.RenderAsync(renderRequest);


        return await GetPdf(report);
    }

Cause it seems like my first render/request always fails and the others works perfectly fine. Similiar problem to this one https://groups.google.com/forum/#!topic/jsreport/mAbgQ_6I8lo

Whenever I make a first request to just builded project, first pdf render always first and throws exceptions like: "Error while copying content to a stream.", "Socket has been closed".

Where do I specify the start time out.

    public PdfService()
    {
        _pdfJsreportCreator = new PdfJsreportCreator();
        _reportingService = new LocalReporting()
            .UseBinary(JsReportBinary.GetBinary())
            .Configure(cfg =>
            {
                cfg.LicenseKey = ConfigurationManager.AppSettings[JS_REPORT_LICENSE];
                return cfg;
            })
            .AsWebServer()
            .Create();
    }

This class is initialized in the api controlled constuctor.
What can I do to fix this proble.
