TypeScript - Helps to draw informations in simple tables using pdfkit. #server-side. Generate pdf tables with javascript (PDFKIT plugin)

const fs = require("fs");
const { PDFDocument } = require("pdfkit-table-ts");

const doc = new PDFDocument({
  margin: 30, 
});

;(async function(){
 
  // to save on server
  doc.pipe(fs.createWriteStream("./example-1.pdf"));

base64 for pdfkit:

import * as PDFDocument from 'pdfkit'
import getStream from 'get-stream'

const pdf = {
  createPdf: async (text: string) => {
    const doc = new PDFDocument()
    doc.fontSize(10).text(text, 50, 50)
    doc.end()

    const data = await getStream.buffer(doc)
    let b64 = Buffer.from(data).toString('base64')
    return b64
  }
}

export default pdf

// --or--

const PDFDocument = require('pdfkit')
const getStream = require('get-stream')

const pdf = () => {
  const doc = new PDFDocument()
  doc.text('Hello, World!')
  doc.end()
  return await getStream.buffer(doc)
}

// Caller could do this:
const pdfBuffer = await pdf()
const pdfBase64string = pdfBuffer.toString('base64')
