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.

JSONLint features and specs

  • User-Friendly Interface
    JSONLint offers a simple and intuitive web interface that makes it easy to validate JSON data without the need for advanced technical skills.
  • Error Highlighting
    The tool highlights exactly where the errors are in the JSON data, making it easier to identify and correct mistakes quickly.
  • Free to Use
    JSONLint is freely accessible to anyone with an internet connection, making it a cost-effective solution for validating JSON data.
  • JSON Formatter
    In addition to validating JSON, JSONLint also offers functionality to format and beautify JSON data, improving readability.
  • Quick Processing
    The tool processes JSON data quickly, providing almost instant feedback which is useful during development and debugging.

Possible disadvantages of JSONLint

  • Internet Connection Required
    JSONLint is a web-based tool, so it requires an active internet connection to function, which can be a limitation in offline environments.
  • Basic Features
    While JSONLint is excellent for simple validation and formatting, it lacks more advanced features like schema validation or integration with development environments.
  • No API
    JSONLint does not offer an API for programmatic access, limiting its use in automated workflows and larger development pipelines.
  • Ads on the Website
    The website includes advertisements, which can be distracting for users and might affect the user experience.
  • Limited Customization
    The tool does not offer much in terms of customization options for how errors are displayed or how JSON is formatted, which might not meet all user needs.

puppeteer Reviews

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.
Source: bugbug.io
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 / 3 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
