Generate PDF From HTML In Angular

As a developer, many times we can be required to convert HTML content to PDF files. So, here I’ll explain about converting HTML content into PDF files in an angular application. For the task, I will use jspdf.
Using the below code, the developer easily converts HTML to PDF files. and using this code convert images to pdf format.

So, let’s see below example from here:

Step 1: Create an Angular app using CLI

Create an Angular Folder and create an angular app with this command

ng new generate-pdf
cd generate-pdf

Step 2: Run the following commands in CLI to install latest packages

This package used to convert HTML data to pdf format

npm i jspdf
npm i html2canvas

Step 3: Update app.component.ts file

Open the app. component.ts file and add the below code.

open the ts file for update code and then put the below code.

import { Component } from '@angular/core';
import { jsPDF } from 'jspdf'
import html2canvas from 'html2canvas';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
  captureScreen() {
    let data = document.getElementById('contentToConvert');
    html2canvas(data as any).then(canvas => {
        var imgWidth = 210;
        var pageHeight = 295;
        var imgHeight = canvas.height * imgWidth / canvas.width;
        var heightLeft = imgHeight;
        const contentDataURL = canvas.toDataURL('image/png');
        let pdfData = new jsPDF('p', 'mm', 'a4');
        var position = 0;
        pdfData.addImage(contentDataURL, 'PNG', 0, position, imgWidth, imgHeight)
        pdfData.save(`MyPdf.pdf`);
    });
}
}

Step 4: Update app.component.html  file

<div>
  <input type="button" value="Convert" (click)="captureScreen()"/>
</div>
<div id="contentToConvert">
  <h2>HTML Table</h2>
  <div>
    <img src="../assets/capture.png" width="300px">
  </div>
<table>
  <tr>
    <th>Company</th>
    <th>Contact</th>
    <th>Country</th>
  </tr>
  <tr>
    <td>Alfreds Futterkiste</td>
    <td>Maria Anders</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td>Centro comercial Moctezuma</td>
    <td>Francisco Chang</td>
    <td>Mexico</td>
  </tr>
  <tr>
    <td>Ernst Handel</td>
    <td>Roland Mendel</td>
    <td>Austria</td>
  </tr>
  <tr>
    <td>Island Trading</td>
    <td>Helen Bennett</td>
    <td>UK</td>
  </tr>
  <tr>
    <td>Laughing Bacchus Winecellars</td>
    <td>Yoshi Tannamuri</td>
    <td>Canada</td>
  </tr>
  <tr>
    <td>Magazzini Alimentari Riuniti</td>
    <td>Giovanni Rovelli</td>
