Puppeteer doesn't close browser

I'm running puppeteer on express/node/ubuntu as follow:

var puppeteer = require('puppeteer');
var express = require('express');
var router = express.Router();

/* GET home page. */
router.get('/', function(req, res, next) {
    (async () => {
        headless = true;
        const browser = await puppeteer.launch({headless: true, args:['--no-sandbox']});
        const page = await browser.newPage();
        url = req.query.url;
        await page.goto(url);
        let bodyHTML = await page.evaluate(() => document.body.innerHTML);
        res.send(bodyHTML)
        await browser.close();
    })();
});

running this script multiple times leaves hundred of Zombies:

$ pgrep chrome | wc -l
133

Which clogs the srv,

How do I fix this?

Running kill from a Express JS script could solve it?

Is there a better way to get the same result other than puppeteer and headless chrome?

Solution

  • I solve it with https://www.npmjs.com/package/shelljs

    var shell = require('shelljs');
shell.exec('pkill chrome')
