Angular2 - Generate pdf from HTML using jspdf

In case someone prefer not to use cdn scripts & would like to use a more (angular) way, this worked for me in Angular 6:

Using this way will give you better support & autocomplete in the editor & will help you avoid depending on cdn scripts (if you wanna avoid them, like me)

Based on the excellent answer here & since it was hard for me to find that answer, I am re-sharing what was stated in it & helped me use jsPDF in Angular 6 (all credit goes to the original author of this answer)

You should run these cmds:

npm install jspdf --save

typings install dt~jspdf --global --save

npm install @types/jspdf --save

Add following in angular-cli.json:

"scripts": [ "../node_modules/jspdf/dist/jspdf.min.js" ]

html:

<button (click)="download()">download </button>

component ts:

import { Component, OnInit, Inject } from '@angular/core';
import * as jsPDF from 'jspdf'
@Component({
  ...
  providers: [
    { provide: 'Window',  useValue: window }
  ]
})
export class GenratePdfComponent implements OnInit {

  constructor(
    @Inject('Window') private window: Window,
    ) { }

  download() {

        var doc = new jsPDF();
        doc.text(20, 20, 'Hello world!');
        doc.text(20, 30, 'This is client-side Javascript, pumping out a PDF.');
        doc.addPage();
        doc.text(20, 20, 'Do you like that?');

        // Save the PDF
        doc.save('Test.pdf');
    }
}

What I found worked was adding:

<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.js"></script>

to the index.html file (it could presumably be elsewhere).

I then used:

const elementToPrint = document.getElementById('foo'); //The html element to become a pdf
const pdf = new jsPDF('p', 'pt', 'a4');
pdf.addHTML(elementToPrint, () => {
    doc.save('web.pdf');
});

Which no longer uses html2canvas in the code.
You can then remove the following import:

import * as html2canvas from 'html2canvas';

Anyone still trying to convert an Html div to a pdf can opt to use html2pdf, with a couple of lines you can do everything with ease.

var element = document.getElementById('element-to-print');
html2pdf(element);
