docs.checklyhq.com VS puppeteer

With risk of tooting my own horn too much, this is exactly why I started my company https://checklyhq.com

We approach it a bit different: we blur the lines between E2E testing and production monitoring. You run an E2E test and promote it to a monitor that runs around the clock.

It's quite powerful. Just an E2E test that logs into your production environment after deploy and then every 10 minutes will catch a ton of catastrophic bugs.

You can also trigger them in CI or right after production deployment.

Big fat disclaimer: I'm a founder and CTO.

Headless Recorder from Checkly might be a cool addition and it supports Playwright and Puppeteer 🙌

At FINN we use Checkly once again to run our scheduled E2E tests. Some teams also use a combination of Make and Apify to run scheduled E2E tests on smaller projects.

This is a good area that needs to be fleshed out, so far the best solution I've found is https://checklyhq.com/

Playwright as a service + other monitoring checks is amazing.

Use Selenium or Third-Party APIs: Utilize tools like Selenium / Puppeteer or third-party APIs such as the Crawlbase Crawling API to load the webpage. These tools can handle JavaScript rendering, ensuring all dynamic content is displayed.

This project tests how the browser language can be changed with Puppeteer. It implements multiple options to set the language of Chrome and checks each option against BrowserLeaks to see how it affected the JavaScript proeprties and HTTP headers available by the browser. For more information, see my article The Puppeteer Language Experiment on DEV.to.

In Crawlee, you can scrape JavaScript rendered websites using the built-in headless Puppeteer and Playwright browsers. It is important to note that, by default, Crawlee scrapes in headless mode. If you don't want headless, then just set headless: false.

Some quick docs fumbling and you get a working script for loading the page and grabbing the innerHTML of the listing element like so:

I am not in any way associated with the developers at puppeteer, but if you are looking for a way to contribute, they are open source

With the advent of tools like Puppeteer and now Playwright, end-to-end testing has become much easier and more reliable. For anyone who's used Selenium in the past, you know what I'm talking about. Puppeteer has opened the way in terms of E2E tooling, but Playwright has taken it to the next level and made it easier to await for certain selectors or conditions to be fulfilled (via locators), thus making tests more reliable and less flaky. Also, it's a game changer that it introduced a test-runner - this made the integration between the headless browser and the actual test code much smoother.

1.Puppeteer: Puppeteer is a Node library that provides a high-level API to control headless Chrome or Chromium using the DevTools Protocol. Key Features: More control over Chrome. Enables web scraping. Allows taking screenshots and generating PDFs for UI testing. Measures load times through the Chrome Performance Analysis tool

HTML to PDF conversion is a common requirement in modern web applications. It allows users to save web pages, reports, and other content in a format that is easy to share and print. There are many libraries and services available for converting HTML to PDF, each with its own strengths and weaknesses. In this article, we will compare some of the most popular HTML to PDF renderers in Node.js, including Puppeteer, Playwright, node-html-pdf, and Onedoc.

Playwright seems to be a superior library for working with headless browsers than Puppeteer, but I will go with Puppeteer.

Puppeteer is a Node library that provides a high-level API to control headless Chrome or Chromium. It's primarily used for browser automation, making it a powerful tool for end-to-end testing of web applications, taking screenshots, and generating pre-rendered content from web pages.
