  Hi @jan_blaha and thank you for help. I've removed index.js from foo directory, so there is no relation to my custom code
  and tried to test again, but the error is still and is as expected "Unable to find module foo".
  It seems as i commented in "berforeRender", that error occurred in second line of code:

  var ds = require('foo');

  and none of my script does not executed. Thus can I explain why after removing index.js
  there is no difference in error in both cases. I think actually jsreport can not find foo. In addition
  the error log that i included in first post shows that

  search path: foo foo /opt/jsreport/foo ....

  jsreport searches foo in /opt/jsreport directory that is false, it must be /opt/jsreport/node_modules.
  Is it correct? Have I understand correctly?

  regards

  Hi Jan,

  I'm running it in dev so I think syncModification is true by default. It works fine with one template.

  The issue is that files seem to get partially detected, so when we are create an entire directory of templates, assets and folders it seems to fail to detect the later files that are created. It's non-deterministic so at best all the files are detected and at worst only assets are detected (as they are the first to be created).

  EDIT: This is currently being locally tested on my Windows 10 machine using nodejs

  Hi Jan!

  I cannot reproduce with the given exemple as it happens only from the imported PDF
  but you can look there as they do disapear on this one (execute sowesign.report by itself first so you can compare)

  https://playground.jsreport.net/w/anon/Ze4gsN1J

  , also I just tried with another PDF from another source and this time charaters that were missing in the first PDF were all present here, I would assume that it might be to how the original PDF was generated (by Word if I got it right) I did however tried with 2 others PDF both generated with word : first one failed because of a max call stack reached :

  this one was quite important and did contain lot of image so I will look deeper into that.

  The second one was shorter and containing lot of special char but some did disapeared again or were replaced (é => i for example). I will try with some more PDF from different sources maybe it is more about how word is encoding the pdf first, which cause conflict during merge operation ?

  Thanks for the reply and the demo @jan_blaha. Yeah the page numbers is quite important in the TOC. Looking forward to either chrome-pdf supporting TOC (came across the feature request in chromium project) as I think going forward this has the best chance to support modern browser features, or for wkhtmltopdf to play nicer with SVGs.

  It depends on the configuration.
  Anyway, if this is an issue for you.
  Make the first rendering during the application initialization as a warmup procedure.

  Thanks a lot for your time,

  I have to deeply apologize on my end as I finally figured out what was wrong :
  the images url list (arround 8k) that was being used was not fully completed during the data generation (arround 4k only)
  hence the recipe would call undefined instead of a proper https://link-to-img, which explain why no more
  image where shown after a certain point in the PDF.
  After fixing the data to contains proper url I could generate correctly the whole PDF with all the images as it should be.

  The good point for us in this process is that we could find out about how chrome-pdf would handle this case and we are quite hapy about it since we still get a PDF at the end. The bad point is that it took too much time for both of us and I do apologize again for that.

  Thanks a lot for your help!

  hi! for sure there is a way to use it without studio, however we don't have docs for use each jsreport extension with just core, however you can do the same that studio does by using the http api that jsreport exposes, and you can check real example of how to do it by checking the studio code of scheduling and see how it executes the POST request to save or run a schedule

  @jan_blaha Hi , is it possible to save the copy of the file that renders in the client side. On client side , the Excel is rendering as the response from the JS Report server .
  So i want to save the file / excel on the server ( before or after hopefully) .
  Any code snippets would be a great help.

  Thanks .

  I was able to make it work by doing this.
  Look into your linked web font
  https://fonts.googleapis.com/css?family=Sarala&subset=devanagari

  There I see url to woff2
  https://fonts.gstatic.com/s/sarala/v2/uK_y4riEZv4o1w9hDBcSAv4.woff2

  Download and rename it.
  Upload it as an asset to jsreportonline.
  Use copy button to get the embedding code and paste it to the template.

  In the end it looks like this.

  <html> <head> <style> @font-face { font-family: 'Sarala'; src: url({#asset Sarala.woff2 @encoding=dataURI}); format('woff2'); } </style> <style> * { font-family: Sarala; } </style> </head> <body> यह निबंध बहु </body> </html>

  Google Docs is just a service for working with docx, odt files.
  jsreport can produce xlsx or docx files that you can open in the Google Docs.
  Unfortunately still don't understand what you request.

  Are you using the latest jsreport,or at least the v2 version?
  The script hooks have different signature there. See the docs
  https://jsreport.net/learn/scripts

  Your script should look like this

  var request = require('request'); function beforeRender(req, res, done){ console.log('hello'); request({ url:"http://127.0.0.1:8000/api/receipts/1", method: "POST", json:true, headers: {'User-Agent':'Super Agent/0.0.1','content-type': 'application/json','Content-Length': 92}, },function(err, response, body){ console.log(body); req.data = {posts:body}; console.log(req.data); done(); }) }
