How js-report input request size calculates?

piyu37

Hi,
I am sending data to js-report in json format which includes object, let's say:
data = {
object a: {object a has 1048 bytes size of data},
object b: {object a has 69168 bytes size of data},
object c: {object a has 38224 bytes size of data},
object d: {object a has 76688 bytes size of data},
object e: {object a has 200 bytes size of data},
object f: {object a has 136 bytes size of data},
object g: {object a has 136 bytes size of data},
object h: {object a has 200 bytes size of data},
object i: {object a has 200 bytes size of data},
object j: {object a has 72 bytes size of data}
}
When I am counting manually the size of these data it's equal to 185,912 bytes(.2 Mb max.) but when this object goes to js-report, the size becomes approx 22Mb and because of that it gives error:
Input request reached limit of 20971520 byte(s)(21 Mb)

Now my question is how js-report calculates the input request size when we send a Json to js-report? How it's becoming 22Mb data? And Is there any way to reduce the size of the data?
Please help me in understanding this.
Thanks in advance!!

This is calculated by some library deep down the dependencies in jsreport. I think it is this one.

To get the size I believe you need to serialize the whole rendering request and calculate number of bytes.
Something like this

JSON.stringify({
  template: { content: ... },
  data: { .... }
}).length*4

Note you can increase the input request limit if you want to.

Awesome, thanks @jan_blaha
Right now I've also did the same i.e. increased the input request limit and it started working fine. :)
