html2pdf.js

html2pdf.js is a client-side library that uses pure JavaScript to make HTML to PDF conversion a breeze. It’s perfect for projects requiring quick and easy PDF generation without a server-side setup.

Basic Setup and Customization

To use html2pdf.js, include the library in your HTML:


<script src="path/to/html2pdf.bundle.min.js"></script>

Then, convert your HTML to PDF with just a few lines of code:


html2pdf().from(element).save();

You can customize the PDF output by setting options like margins, filename, and page orientation:


var options = {

margin: 1,

filename: 'myDocument.pdf',

pagebreak: {

mode: ['css', 'legacy'] }

};

html2pdf().set(options).from(element).save();

Page-Break Management

Managing page breaks is crucial for a clean document layout. html2pdf.js offers options to control page breaks, ensuring your content is split neatly across pages:


var options = {

pagebreak: {

mode: 'avoid-all',

before: '.page-break' }

};

html2pdf().set(options).from(element).save();

In this example, page breaks are avoided around elements with the class .page-break helps you maintain a polished look for your PDFs.

jsPDF: Generating PDFs with JavaScript

jsPDF is a powerful library that allows you to create JavaScript PDF documents. It’s versatile, supporting various content types like text, images, and vector graphics, making it a popular choice for HTML to PDF conversion.

Implementing jsPDF

To start using jsPDF, include the library in your HTML:


<script src="path/to/jspdf.min.js"></script>

Then, create a new PDF document and add content:


var doc = new jsPDF();

doc.text('Hello world!', 10, 10);

doc.save('myDocument.pdf');

You can read HTML content and convert it to PDF using jsPDF:


var doc = new jsPDF();

var elementHTML = document.getElementById('content').innerHTML;

doc.fromHTML(elementHTML, 15, 15);

doc.save('myDocument.pdf');

Custom Styles and Page Breaks

jsPDF allows you to customize the style of your PDF:


doc.setFont('Arial');

doc.setFontSize(14);

doc.setTextColor(255, 0, 0);

Managing page breaks can be done by manually adding new pages:


doc.addPage();

With jsPDF, you have the flexibility to generate PDFs with custom styles and manage content across multiple pages for a professional-looking document.

Puppeteer: Advanced HTML to PDF Conversion

Puppeteer is a powerful Node.js library that provides a high-level API to control Chrome or Chromium over the DevTools Protocol. It’s perfect for generating PDFs from HTML, especially for complex pages or when you need more control over the rendering process.

Generate a PDF with Puppeteer

To get started with Puppeteer for PDF generation, first install the library:


npm install Puppeteer

Then, use the following code to generate a PDF:


const puppeteer = require('puppeteer'); (async () => {

const browser = awaitpuppeteer.launch();

const page = await browser.newPage();

awaitpage.goto('https://example.com', {

waitUntil: 'networkidle2'

});

await page.pdf({

path: 'example.pdf', format: 'A4'

});

await browser.close();

}) ();

This code launches a headless browser, navigates to a webpage, and saves it as a PDF file.

Advanced Customization

Puppeteer offers advanced customization options for PDF generation, such as setting page margins, format, and scale:


await page.pdf({

path: 'example.pdf',

format: 'A4',

margin: {

top: '20px',

right: '20px',

bottom: '20px',

left: '20px'

},

scale: 0.8

});

You can also emulate media types, capture specific elements, and much more, making Puppeteer a versatile tool for any PDF generation requirement.
