Generate pdf with jspdf and Vue.js

I am new with Vue.js, and I am trying to generate a PDF, but I have no idea how to do it.

This is what I have:

import * as jsPDF  from "jspdf"

export default {

  props: ['id'],


  methods: {
    pdf () {
      const doc = new jsPDF()
    }
  }

}

Error:

Property or method "pdf" is not defined on the instance but referenced during render

I had similar issue, especially with generating proper size and resolution.

To keep it brief, below is a link to the post:

Using jsPDF, html2Canvas, and Vue to generate PDF's

I modified for my use:

downloadItem() {
        const invoiceName = this.currentInvoice.invoiceId,
              content = this.$refs.invoiceContent;

        const doc = new jsPDF({
            orientation: "landscape",
            unit: "px",
            format: "a4",
            hotfixes: ["px_scaling"],
        });

        html2canvas(content, {
            width: doc.internal.pageSize.getWidth(),
            height: doc.internal.pageSize.getHeight(),
        }).then((canvas) => {
            const img = canvas.toDataURL("image/png");

            doc.addImage(
                img,
                "PNG",
                140,
                10,
                doc.internal.pageSize.getWidth(),
                doc.internal.pageSize.getHeight()
            );

            doc.save("invoice-" + invoiceName + ".pdf");
        });
    },

Download html page content, One can follow as:

Specify the ref to the element, whose content you want to download as pdf

<div ref="content">
   ....
   ..
</div>

Create a button download like

<button @click="downloadWithCSS">Download PDF</button>

Make sure to add & import jsPDF library into vue-component

import jsPDF from 'jspdf' 
import domtoimage from "dom-to-image";


Specify the method into the VUE component like

methods: {
 downloadWithCSS() {

   /** WITH CSS */
    domtoimage
    .toPng(this.$refs.content)
    .then(function(dataUrl) {
      var img = new Image();
      img.src = dataUrl;
      const doc = new jsPDF({
        orientation: "portrait",
        // unit: "pt",
        format: [900, 1400]
      });
      doc.addImage(img, "JPEG", 20, 20);
      const date = new Date();
      const filename =
        "timechart_" +
        date.getFullYear() +
        ("0" + (date.getMonth() + 1)).slice(-2) +
        ("0" + date.getDate()).slice(-2) +
        ("0" + date.getHours()).slice(-2) +
        ("0" + date.getMinutes()).slice(-2) +
        ("0" + date.getSeconds()).slice(-2) +
        ".pdf";
      doc.save(filename);
    })
    .catch(function(error) {
      console.error("oops, something went wrong!", error);
    });
 },
}

  });
  doc.save("sample.pdf");
 },

 downloadWithCSS() {
   const doc = new jsPDF();
   /** WITH CSS */
   var canvasElement = document.createElement('canvas');
    html2canvas(this.$refs.content, { canvas: canvasElement 
      }).then(function (canvas) {
    const img = canvas.toDataURL("image/jpeg", 0.8);

First import the PDF library as:

import jsPDF from 'jspdf'

Then simply instantiate the object and give it the contents: 

methods: {
  createPDF () {
    let pdfName = 'test'; 
    var doc = new jsPDF();
    doc.text("Hello World", 10, 10);
    doc.save(pdfName + '.pdf');
  }
}

Make sure to read the documentation for more
