Generate PDF on NodeJS with Puppeteer & EJS

pdf.js

const ejs = require('ejs')
const puppeteer = require('puppeteer')
const fs = require('fs')
const { Buffer } = require('buffer')
const { PDFDocument } = require('pdf-lib')

async function createPDF({ template, data, output, title = 'Laporan', format = 'A4' }) {
  const content = ejs.render(fs.readFileSync(template).toString(), data)

  const browser = await puppeteer.launch({
    headless: true,
    args: [
      '--no-sandbox',
      '--disable-setuid-sandbox',
      '--disable-3d-apis',
      '--disable-web-security',
      '--font-render-hinting=none',
    ],
  })
  const page = await browser.newPage()
  await page.goto('data:text/html,' + content, { waitUntil: 'networkidle0' })
  let pdf = await page.pdf({
    format,
    path: output || null,
    margin: {
      top: '20px',
      bottom: '20px',
      left: '20px',
      right: '20px',
    },
  })
  
  browser.close()
  
  // Set the title   
  pdfdoc = await PDFDocument.load(pdf)
  pdfdoc.setTitle(title)
  
  pdf = await pdfdoc.save()
  return Buffer.from(pdf)
}


// Use
const pdf = await createPDF({
  template: path.resolve(__dirname, 'templates', 'template.ejs'),
  title: "My PDF Title",
  data: { name: 'John Doe', age: 34 },
})

This is cool! What's the purpose of the template.ejs? Are you writing a blog, been wanting to createPDFs on my server

Thank's @WisaniShilumani, No, I just want to generate some complex data report with pdf format (also with some merge cells)... and I think the cleaner way is to using template engine like EJS. BTW I try jsPDF before, but its hard to create table especially when centering things. The only advantage is it can be run on browser.
