In this article, We will explain to you how to generate a pdf file using puppeteer in node.js. normally puppeteer is a node library and it is developed by Google.

Here in this article, we have created a simple application so you can understand.

const port = 3000;
const puppeteer = require ('puppeteer');


app.get("/html2pdf", (req, res, next) => {
var html ='<h2>XpertPhp</h2>';
	(async function () {
		try { 
			const browser = await puppeteer.launch();
			const page = await browser.newPage();
			await page.setContent (html);
			
			await page.emulateMedia ('screen');
			const pdf = await page.pdf({ format: 'A4',printBackground: true });
			res.set({ 'Content-Type': 'application/pdf', 'Content-Length': pdf.length });
			res.send(pdf);
		}catch (e) {
		console.log ('our error', e);
		}
	})() ;
});

app.listen(port, () => console.log(`Example app listening on port ${port}!`))

const express = require('express');

const app = express();

const port = 3000;

const puppeteer = require ('puppeteer');

app.get("/html2pdf", (req, res, next) => {

var html ='<h2>XpertPhp</h2>';

(async function () {

try {

const browser = await puppeteer.launch();

const page = await browser.newPage();

await page.setContent (html);

await page.emulateMedia ('screen');

const pdf = await page.pdf({ format: 'A4',printBackground: true });

res.set({ 'Content-Type': 'application/pdf', 'Content-Length': pdf.length });

res.send(pdf);

}catch (e) {

console.log ('our error', e);

}

})() ;

});

app.listen(port, () => console.log(`Example app listening on port ${port}!`))

If you want to the download pdf file in your directory then you can use the below code.

await page.pdf ({
	//name of your pdf file in directory
	path: 'testpdf.pdf', 
	format: 'A4', 
	printBackground: true
});
await browser.close();
process.exit();

await page.pdf ({

//name of your pdf file in directory

path: 'testpdf.pdf',

format: 'A4',

printBackground: true

});

await browser.close();

process.exit();

Finally, you can run the application follow the below URL.

http://localhost:3000/html2pdf
