Dears,
I would like to insert a page break (start on new page) each object in an array of objects, in other words, i want to have each item on as much papers as it needs, but the second item of the array should start on a new page.
I looked all over the web, and coulndt seem to find something working.
I am using jsreport on nodejs .
Please i need a proper guide.
Thanks in advance.
Dears,
I am rendering my report with an automatic fit to page setting. I would like to disable this feature, how can i do so?
i would like to have columns that overflow the page and wont be displayed / printed on another pape.
Thanks in advance.
Hi guys, i have the following example:
var path = require('path');
var fs = require('fs');
var request = require('request');
var jsreport = require('jsreport-core')(
{
"tasks": {
"allowedModules": "*"
}
}
);
jsreport.use(require('jsreport-handlebars')());
jsreport.use(require('jsreport-templates')());
jsreport.use(require('jsreport-xlsx')());
exports.productionExcelPrint = (req, res, next) => {
jsreport.init().then(() => {
return jsreport.render({
template: {
content: fs.readFileSync(path.join(__dirname, 'productionExcel.handlebars')).toString(),
engine: 'handlebars',
recipe: 'xlsx'
}
}).then(function (res) {
res.stream.pipe(fs.createWriteStream('out.xlsx'))
});
}).catch(function (e) {
console.log("error here: ", e)
});
};
and my template "productionExcel.handlebars"
{{#xlsxAdd "xl/worksheets/sheet1.xml" "worksheet.sheetData[0].row"}}
<row>
<c t="inlineStr"><is><t>LOB</t></is></c>
</row>
{{/xlsxAdd}}
{{{xlsxPrint}}}
and im getting this error:
error here: { Error: Unable to parse xlsx template JSON string (maybe you are missing {{{xlsxPrint}}} at the end?):

@bjrmatos @jan_blaha please guys i need your help to figure it out.
Thanks in advance.
Dears,
Am I able to pass a Data Array to this:
jsreport.documentStore.collection('templates').insert({
content: 'footer',
shortid: 'footer',
engine: 'handlebars',
recipe: 'chrome-pdf'
});
Hello @bjrmatos, my data returned from the api has the same format as the one in policyData.json, but it is around 6.5mb in size.
Even if i increased the timeout, it still shows the same error (Timeout exceeded).
Loading the data is no problem for me, im getting this error after trying to add a custom page number to pdfGroups (Just as it shows in the repo).
I have updated the policyData.json with the exact response from api, having an array of 200 elements, and still getting the same error.
Please checkout the updated repo.
I reduced the elements of an array to 47, and this is the max number of elements that works, and took 118 seconds to render.
Your help is much appreciated.
Thanks in advance.
@bjrmatos this will be done by tomorrow, I will update my post here after I have updated my repo.
Can we increase the default timeout of 30s, if that is the problem?
Thanks for the support and quick reply.
Hi @bjrmatos, the data returning from the endpoint is the same in the policyData.json but x1000, maybe thats why its not loading correctly? Or doesnt have enough time to load with the correct page numbers ??
Thanks in advance
@jan_blaha @bjrmatos please, i need some guidance on solving this problem. Thanks in advance
Dears,
i tried following this example https://playground.jsreport.net/studio/workspace/B1c8HcCix/229 but on jsreport-core nodejs, but it doesnt seem to work.
1- I am not able to read and execute the watermark.js file via {#asset {{watermark.js}}}
2- I tried to call this functionality inside watermark.js as a helper {{myWatermark}}, but since its a backend server rendering, the error was "document.height" document wasnt defined.
Any guidance please?
yes sir, my repo: https://github.com/anthony-elhaddad/jsreport-jsreport-pdf-util
The error is happening when im using
recipe: 'chrome-pdf',
in
jsreport.render({
template: {
content: fs.readFileSync(path.join(__dirname, 'policyPrint.hbs')).toString(),
engine: 'handlebars',
recipe: 'chrome-pdf',
helpers: helpers,
pdfOperations: [{ type: 'merge', renderForEveryPage: true, templateShortid: 'header' }],
}
instead of
recipe: 'phantom-pdf',
And i need to use chrome-pdf to have the ability to use
jsreport.documentStore.collection('templates').insert({
content: "{{myHelper}}",
shortid: 'header',
engine: 'handlebars',
recipe: 'chrome-pdf',
helpers: helpers,
chrome: {
width: '15cm',
height: '1cm'
},
});
Thanks in advance
Error: Navigation Timeout Exceeded: 30000ms exceeded
at Promise.then (C:\Users\jsreport-git\node_modules\puppeteer\lib\NavigatorWatcher.js:71:21)
at <anonymous>
How to solve this?
My data is coming from an api call.
I wasnt getting this error before using the pdf-utils.
Hi @bjrmatos,
My git repo has been updated with your solution.
I have managed to follow your guidance and got an output.
I am interested in knowing how many pages each object in the data array(which has for now 2 objects) took.
For example: first object in the array took 3 pages, i would like to have it displayed on the report, "1/3 " on the first page, "2/3" on the second and "3/3" on the third.
For the second object, lets assume it took 2 pages, it should display "1/2", and the second page "2/2".
What im looking for is: pageNumber and pageIndex of each group, in other words group.pageNumber, group.pageIndex, group.totalPages ... Something like that.
How can I reach this functionality?
Thanks in advance.
----- EDIT -----
Please check my repo, and generate a report for latest update
Thanks in advance.
----- EDIT 2 -----
Instead of retrieving data from mock file, i am getting them from an api call using
request(url, { json: true }, (error, response, body) => {
// manipulate the data
// to have a proper format
// similar to the mock
// call jsreport.render .... (similar to the repo)
});
the data retrieved and manipulated is around 2000 records.
i am getting the following error:
Error: Navigation Timeout Exceeded: 30000ms exceeded
at Promise.then (C:\Users\jsreport-git\node_modules\puppeteer\lib\NavigatorWatcher.js:71:21)

GET /test/policy - - ms - -
I tried changing the
"strategy": "in-process"
to
"strategy": "http-server"
but nothing works.
Try following this tutorial, https://jsreport.net/on-prem
https://github.com/anthony-elhaddad/jsreport-jsreport-pdf-util
Please check this repo, and navigate to controllers/underwriting/policyPrint/policyPrint.controller.js
this is where im stuck.
'{{$pdf.pageNumber}}/{{$pdf.pages.length}}', is not returning any value.
Your help is much appreciated.
navigate to http://localhost:3000/test/policy to test the pdf
Dears,
I am facing some problems with jsreport-pdf-utils in a nodejs based app.
i have the following:
jsreport.init().then(function () {
return jsreport.render({
template: {
engine: 'handlebars',
content: "{{$pdf.pageNumber}} / {{$pdf.pages.length}}<h1>Hello from Page 1</h1> <div style='page-break-before: always;'></div><h1>Hello from Page 2</h1><div style='page-break-before: always;'></div><h1>Hello from Page 3</h1>",//fs.readFileSync(path.join(__dirname, 'policyPrint.hbs')).toString(),//'<h1>Hi World{{foo}}</h1>',
shortid: 'header',
recipe: 'phantom-pdf',
helpers: '',//helpers,
pdfOperations: [{type: 'merge', renderForEveryPage: true, templateShortid: 'header' }]
},
this example is taken from https://playground.jsreport.net/studio/workspace/BkEHf9MNG/5
and trying to make it work in a nodejs based app, but i cant seem to get it working.
an error is occurring:
Error: Engine must be specified
at invokeRender (C:\code\myTestApp\node_modules\jsreport-core\lib\render\render.js:67:11)
any idea how to solve it?
Thanks in advance.
Hi again,
I am using jsreport-core on top of an existing nodejs app, is there any configuration example available to include the {{pdfCreatePagesGroup }} ?
Thanks in advance.
----- EDIT -----
I have the following configuration
return jsreport.render({
template: {
content: fs.readFileSync(path.join(__dirname, 'policyPrint.hbs')).toString(),
engine: 'handlebars',
shortid: 'header',
recipe: 'phantom-pdf',
helpers: helpers,
****pdfOperations: [{ type: 'merge', renderForEveryPage: true, templateShortid: 'header' }]****
},
and in the helpers.js that im referencing, i have the following method:
function mySum() {
return this.$pdf.pages[this.$pdf.pageIndex].items.reduce((a,c) => a + c)
}
and in the policyPrint.hbs i have
{{{pdfCreatePagesGroup name="Jan" age=33}}}
{{mySum}}
but my problem here is, whenever the helper mySum gets called, an error occurs saying: cannot read property pages of undefined, whereas the value of this.$pdf is undefined in my helpers.js
Any guidance please?
Hi,
I have a question regarding the page number and number of pages.
I have an array of data that im passing it to jsreport to draw it on the .hbs file.
using {{#each this}} to loop through the array and display items on the template, i would like to know for each item in that array, how many pages it is using off the report, and i would like to display them; example:
lets say the array has 3 items, the first item takes 5 pages of the report, i would like to add on each page (1 / 5, 2 / 5, ...).
For the second item in that array, lets say it needs 7 pages, i want it to display (1/7, 2/7, ... )
any guidance please?
i have a download button on my Angular project, on click it goes to the server at http://localhost:3000/test/printPolicy , and will get me the pdf content to download it from Angular(Client side). The report is a heavy one and needs around 9000ms to be downloaded.
i added another button but referencing the same method that calls the server at http://localhost:3000/test/printPolicy. (should get me the same report)
On testing: i have clicked the button1 then button2 and my result was: I waited 9000ms to get the first report and another 9000ms to get the second report.
My question is here: What can I do to make them load simultaneously, not having to wait another 9000ms to get the second one.
EDIT -------
Fixed, To test it, open a new browser, dont use the incognito mode of the same browser.
hi guys,
i tried this, and it doesnt work.
what i tried as well, was clustering the http requests in nodejs, but no luck.
i noticed that on the first window, the jsreport engine contacts localhost for loading, while the other window is "waiting for cache", and after the first window loads, it then begins loading.
any guidance please?
PS: i got a download button with its route to nodejs's jsreport. i am opening multiple screens of the same view and testing.
