jsreport init and render problem, when to init jsreport using nodejs and createServer

cooxel

Hi, i'm using jsreport for a small task.
Having templates file to read, i first read all the files, store them in vars, then starting the rendering.

.then(fileContent => {
        jsreport.init().then(() => {
          jsreport.render({
            template: { ... }

All of this is inside:

http
  .createServer((req, res) => {

So everytime a request comes to the node server it tries to re-initiate jsreport, giving me errors, of course.
I removed the piece where i init jsreport, leaving only the render.
It works now.
What i wanted to ask is, would be possible to initiate jsreport before the server, and then use jsreport.render() only when the server is called?

I tried putting

const jsreport = require('jsreport')().init();

at the start, but then jsreport.render doesn't work.

Appreciate your help,
Thanks

You can do something like

const jsreport = require('jsreport')()

jsreport.init().then(() => {
  // the rest of your app init
  http.createServer....
})

Hi @jan_blaha , i tried that, and it works well.
Is it normal that for the first rendering request it takes almost the triple of time than the second request?
Thanks again!

It depends on the configuration.
Anyway, if this is an issue for you.
Make the first rendering during the application initialization as a warmup procedure.
