How can I generate PDF files using JavaScript?
To generate PDF files using JavaScript, you can use libraries like js PDF that provide methods to create and manipulate PDF files directly in the browser.
You can add text, images, and other content to a PDF, customize its layout, and then save or download the generated file.
There are several libraries and approaches to generate PDF files using JavaScript:
1. jsPDF
jsPDF is a popular JavaScript library for generating PDFs. It provides a simple API for creating PDF documents.
Example: const doc = new jsPDF
doc.text (‘Hello, world!’, 10, 10)
doc.save (‘example.pdf’)
2. PDFMake
PDFMake is another popular library for generating PDFs. It provides a more comprehensive set of features, including support for tables, images, and more.
Example:
const docDefinition = {content: ‘Hello, world!}
pdfMake.createPdf (docDefinition).download (‘example.pdf’)
3. Puppeteer
Puppeteer is a Node.js library developed by the Chrome team that provides a high-level API for controlling a headless Chrome browser. It can be used to generate PDFs from HTML content.
Example:
const puppeteer = require(‘puppeteer’)
(async () => {
const browser = await puppeteer.launch()
const page = await browser.newPage()
await page.goto(‘https://example.com’)
4. html2pdf.js
html2pdf.js is a lightweight JavaScript library that converts HTML content to PDF.
Example:
const html2pdf = require(‘html2pdf.js’)
const html = ‘<h1>Hello, world! </h1>’
html2pdf (html, ‘example.pdf’)
