puppeteer features and specs

  • Headless Browsing
    Puppeteer allows headless browsing, which means you can automate and test web applications without opening a browser user interface, resulting in faster execution and lower resource usage.
  • Full Browser Control
    Enables full control over Chrome or Chromium browsers, allowing for comprehensive browser testing and automation, including taking screenshots, generating PDFs, and capturing web pages.
  • Rich API
    Offers a rich set of APIs that can control browsers, manage cookies, intercept network requests, and handle various browser events, making it versatile for different use cases.
  • Active Community
    Highly active open-source community with regular updates and a plethora of plugins and extensions, providing robust support and continuous improvements.
  • Compatibility
    Supports the latest JavaScript features and works seamlessly with popular libraries and frameworks, providing a modern development experience.

Possible disadvantages of puppeteer

  • Restricted to Chrome/Chromium
    Puppeteer is primarily designed to work with Chrome and Chromium browsers, limiting cross-browser testing capabilities compared to other tools that support multiple browsers.
  • Resource Intensive
    Running multiple instances of headless browsers can be resource-intensive in terms of CPU and memory usage, potentially affecting performance on limited hardware.
  • Learning Curve
    Requires some learning curve for developers unfamiliar with browser automation or the Puppeteer API, making initial setup and usage potentially time-consuming.
  • Lacks JavaScript Redaction
    Unlike some other tools, Puppeteer does not natively support JavaScript error redaction, which means developers must manage error handling and debugging themselves.
  • Not Ideal for GUI Tests
    Since Puppeteer is headless by default, it might not be ideal for GUI end-to-end tests that require visual validation, requiring additional tools or configurations to enable full browser displays.

Unused CSS features and specs

  • Performance Optimization
    Removing unused CSS can lead to faster page load times, improving user experience and potentially boosting SEO rankings.
  • Reduced File Size
    By eliminating unused CSS, the overall file size of stylesheets is reduced, which can decrease bandwidth usage and server load.
  • Improved Maintainability
    Cleaned-up CSS makes it easier for developers to read and maintain the stylesheet, reducing the complexity of future updates.
  • Fewer Rendering Issues
    By having only the necessary CSS, the likelihood of rendering issues and style conflicts is minimized, ensuring a more consistent design across different browsers and devices.

Possible disadvantages of Unused CSS

  • Potential Over-removal
    There is a risk of mistakenly removing CSS that is conditionally used (e.g., dynamic content or styled via JavaScript), which can lead to broken styles on the website.
  • Initial Setup Complexity
    Setting up tools to analyze and trim unused CSS can be complex, requiring time and technical expertise to configure properly.
  • Regular Maintenance
    Web applications that frequently change or add new content may require ongoing checks to ensure CSS remains optimal, which could increase maintenance efforts.
  • Risk of False Positives
    Automated tools might misidentify CSS as 'unused' if they're used in specific contexts not covered during the analysis phase, potentially leading to functionality issues.

Top Selenium Alternatives
Puppeteer offers more direct and tighter integration with Chrome or Chromium through the DevTools Protocol, unlike Selenium which abstracts the browser interaction through WebDriver, making it more versatile across different browsers but potentially less optimized for specific browser internals like those Puppeteer accesses in Chrome.

Best Data Scraping Tools
It is completely free. Puppeteer is well backed and supported by Google Chrome and hence replacing Selenium and PhantomJS. It automatically installs an efficient, compatible Chromium binary in its setup, therefore reducing the burden of keeping track on your browser.
Puppeteer vs Selenium
If you're looking for a better alternative, try Endtest. It has Puppeteer's speed, it supports Selenium's browsers AND it has all the features that they're missing.

  • End-to-End SEO Testing with Playwright and Lighthouse
    Vitest is a next-generation JavaScript testing framework powered by Vite. It’s an excellent alternative to Jest, offering native TypeScript support, a fast setup, and solid performance. However, while it has an experimental headless browser, it’s not ideal for advanced scenarios like running SEO audits in CI/CD pipelines. Instead, we can pair Vitest with Pupetter, a more mature tool for headless browser automation. - Source: dev.to / 2 months ago
  • The Puppeteer Language Experiment
    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. - Source: dev.to / about 1 year ago
  • Scrapy Vs. Crawlee
    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. - Source: dev.to / about 1 year ago
