3. electron-pdf on Windows / NodeIIS timeouts

electron-pdf on Windows / NodeIIS timeouts

  • S

    I can't get electron-pdf rendering to work. Tried both electron and electron-prebuilt.

    Is there anything I can change in the config or something to make it work? Better ways to debug this are also welcome..

    This is about the only thing I can get out of the logs.

  • Does the server machine where it runs have more than one core?
    Do you get timeout for simple "Hello world" or just for your particular template?

    Yeah it's configured with 2 cores right now. And I'm just rendering a Hello world, so the template shouldn't be intensive in any way.

    @srijken what is your jsreport config? what version of electron have you installed? and how you installed it, are you using electron or electron-prebuilt package? also try to run jsreport with DEBUG=electron-* env var to get more logs of what is going on and share it here

    @srijken also, can you try to run jsreport outside of IISNode and test if it works? just like a raw node.js app.. previously we had bad experiences trying to make it work https://github.com/bjrmatos/electron-html-to/issues/18 , IISNode is a special environtment because it reimplements some parts of node.js and has some runtime differences that make it difficult to support, so at this point i'm not 100% sure that electron works under IISNode

    Tried both electron and electron-prebuilt. Currently electron is installed version 1.6.6.

    When running without IISNode it works as expected. This setup works for me just as well..

    What's the best way to run jsreport as a windows service so that it starts op when the machine boots?

    0
  • administrators

    @srijken you can use the winser module (that under the hood uses nssm, which you can use directly if you like) to wrap jsreport as a windows service where you can configure that the service should start on machine's boots.

    you can also use our jsreport win-install cli command to execute this for you

    Thanks, that works

    One more question about jsreport win-install: How can I configure it to run in production instead of develop?

    0
  • administrators

    @srijken just set NODE_ENV = production before running the command, in windows is something like this: set NODE_ENV production && jsreport win-install
