Blank Page When Appending Reports

chriscrowley

I have four 2-page "Order" report templates. These reports can be generated separately just fine. The user also wants to print all four reports at once. To do this, I created another "OrderAll" report, which is blank and under pdf-utils I added all four templates as "append", but now I have a blank first page. I could reorder them and set them all as "prepend", but then I get a blank page at the end (the best option, but still not perfect). If I set the first template template as "merge" it looks great, but it's missing the first template's second page. Is there an easier way to print four 2-page report templates at once without having a blank page?

You can implement the pdf utils operations problematically inside scrips. Check the documentation. This opens many approaches to you.

Perhaps the simplest is just to use removePages to remove the first page.

const jsreport = require('jsreport-proxy')

async function afterRender (req, res) {
    res.content = await jsreport.pdfUtils.removePages(res.content, 1)
}

Is pdfUtils.removePages a newer function?

Since 2.10.0 apperantly.

I'm afraid to upgrade to the newest version because it'll probably break stuff. Is it possible to upgrade to version 2.10.0?
Would the command line to upgrade be?:

npm install @jsreport/jsreport-cli@2.10.0 -g

Open your package.json, update the dependency jsreport to the 2.10.0, and hit npm install.

However, the 2.11.0 is the last v2 version and should be the most stable.

Upgrading to 2.11.0 did the trick. Thanks!
