Make sure pdf is ok before send to client

[Quách Thị Gia]

Hello, I create a jsreport server on linux. But currently it has an error displaying the font as below

the correct is: "Xác nhận"

But I deploy it in many different services so I don't want to change all that code. So I want to do something after jsreport generates PDF like below:

I wonder if there is a way to override the jsreport.render function so that it adds a check before returning it. If there is an error, then recreate it. Or another way that you suggest?

P/s:
Because it's happen randomly so i use this way

Can't you install the fonts on the particular servers? With something like

apt install -y fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst 

I wonder if there is a way to override the jsreport.render function so that it adds a check before returning it.

The easiest would be to add the custom jsreport script and afterRender hook that will check whats needed and run the render again.

Hello.

Case wrong font:

I copy folder with files like below into linux and install font. In jsreport.config.json i set:
"pdf": {
"fontDirectory": "/root_etc/fonts/"
},

Most of the times it works fine. But sometimes the system load is exceptionally high. The font will be wrong.

Case rerender i use it but not work:

const jsreport = require('jsreport')()
async function afterRender (req, res) {
	
	console.log("----------------------------- HELP...")
    // do some checks if res.content is ok
    if (req.data.counter > 10) {
	console.log("----------------------------- XXXX...")
        return
    }
        
    const r = await jsreport.render({
        template: { ...req.template },
        data: { ...req.data, counter: (req.data.counter || 0) + 1 }
    })
    res.content = r.content  
}
if (process.env.JSREPORT_CLI) {
  // export jsreport instance to make it possible to use jsreport-cli
  module.exports = jsreport
} else {
	console.log("INIT!")
  jsreport.init().then(() => {
    // running
  }).catch((e) => {
    // error during startup
    console.error(e.stack)
    process.exit(1)
  })
}
