Unfortunately no, I saw this demo before, but what I am trying to do is to dynamically generate templates by script using jsrender and at the end of the script append them using pdf-utils

Ch.K

Hello,

I need to know if it is possible to add TOC using pdf utils for my scenario.
I have a main template that loop on data and generate tens of templates after that.

My setup is something similar to this admin playground
https://playground.jsreport.net/w/admin/UpVVJcAk

Is it possible to add TOC for this type of documents?

Thanks

I will elaborate what I am trying to do and what I am expecting to get
I have a list of templates that i need to generate. Using the jsreport-aws-s3-storage I was able to successfully upload the files to S3.

1st Try

for(var i in templates){
    var resp_pdf = await jsreport.render({ 
        template: { 
            name: templates[i].name
            recipe: 'chrome-pdf'
        }, 
        data: templates[i].data, 
        options: {
               "reports": { "async": true, "blobName": templates[i].name},
               "reportName": templates[i].name
         }                   
     })
}

However I need to find a way to make a callback call once all files has been generated and uploaded to S3.

For that reason I tried first to put the above code at beforeRender of the main template and I was expecting that doing the callback from afterRender will take place only once all all files are on S3.

await axios.get(CALLBACK_URL...

But somehow, I was getting the response sooner, before all files has been sent to S3.

2nd Try
I tried to count the generated files and then fire the CALLBACK as following

toRender = 100;

for(var i in templates){
    var resp_pdf = await jsreport.render({ ... })

    if(resp_pdf) rendered++;
    if(rendered==toRender){ // CALLBACK }
}

Using this setup I noticed that the callback was fired as soon as all PDF files has been generated regardless if all of them has finished upload to s3 or not.

I am open for suggestions, Is there a better way to fire callback once all files has been uploaded ?

Thanks

Hello,

I am trying to upload the pdf rendered files to an aws S3 using the jsreport-aws-s3-storage

My setup could be described as following:

mainTemplate is an empty template used to populate the list of reports to be generated and then
within mainTemplate @afterRender, we call new templates using jsreport.render({ ...})

we are using jsreport-aws-s3-storage plugin to store the generated output on aws server.

I need to be able to detect once the pdf files has been uploaded successfully to aws.

Thanks
