  Yes, you can use a custom jsreport script where you can code what you need
  https://jsreport.net/learn/scripts
  https://jsreport.net/learn/pdf-utils#usage-in-script

  const jsreport = require('jsreport-proxy') async function afterRender (req, res) { res.content = await jsreport.pdfUtils.merge(res.content, Buffer.from(req.data.externalPdf, 'base64')) }

  Full demo here

  It works the way jsreport takes your html as is and puts it into the docx file source.
  When you open the Word app, it interprets the HTML.
  jsreport does not influence how it is interpreted.

  Perhaps you can try the docx recipe and docxHtml helper, if you need to display just a simple html.
  This would let you modify the page size and orientation in the word template.

  Thanks for the follow-up, I like that idea because this way I wouldn't be polluting the default behavior of existing reports with components already. I'll try this approach for sure!

  xlsxAddImage dimensions

  Currently, xlsxAddImage takes the following arguments:
  imageNameOrOptions, sheet id, column from, row from, column to, row to.
  This is similar to Excel's "Place in cell" option for inserting images.
  This forces cells to be sized to a specific size so the image doesn't become distorted.
  An option similar to Excel's "Place over cells" for inserting images would be very useful, passing the following arguments:
  column from, row from, image width, image height
  or
  image left, image top, image width, image height

  The custom users need to be persisted.

  However, you can create a startup script that will import or create them.

  Worker terminated due to reaching memory limit: JS heap out of memory

  See this config
  https://jsreport.net/learn/configuration#workers
  https://nodejs.org/api/worker_threads.html#worker_threads_worker_resourcelimits

  Could you please let us know the default heap size?

  These are the runtime/nodejs settings.
  Each thread gets the same default limit as the main thread
  ~1.5 GB on 64-bit systems

  How many percentage of RAM should be allocated to heap?

  There is no rule of thumb, try what works best for you.
  The main thread can remain in default, and the rest can be divided among workers.

  If we have set only one worker then why are we getting heap size limit issue?

  Because every worker has the nodejs default limit.

  Do references held by previous renders get freed up after report rendering finishes?

  nodejs is the garbage-collected runtime. So it gets cleaned from memory when the GC gets triggered by the runtime.

  hi!!

  you should be able to execute the cli without the global installation by doing any of the following methods:

  (all methods assume you execute the command from the root of your project)

  executing npx jsreport <command> executing node node_modules\.bin\jsreport <command>

  if this does not work, please share more details, like:

  the jsreport version you are using where are you trying to execute this? local machine? server? windows? linux? do you execute this manually? or are you using some CI or automated process?

  The xlsx recipe, when you use xlsxAdd, already use batching and streaming internally.
  Do you hit an OOM error when having many rows?

  You can send the export or compressed data folder...

  I cannot imagine why the perf would be different when using external config. Maybe some kind of disk virtualization/docker/os issue.

  Anyway, what if you test things without Docker first and then troubleshoot the containerization issues?

  Hi,

  We will update the deps to provide a clean audit report during the next release. As always...

  We don't have a date yet, though.
