PhantomJS vs Puppeteer: What are the differences?
Introduction
In this article, we will compare PhantomJS and Puppeteer, two popular tools for automating web browser interactions. We will highlight the key differences between these two tools and examine their unique features and strengths.
Execution environment: PhantomJS is a headless browser that uses the WebKit rendering engine, while Puppeteer is a library developed by Google that controls headless Chrome or Chrome in a full browser mode. This difference in execution environment affects the way scripts are run and the compatibility with different browser features.
Maintenance and support: PhantomJS is no longer actively maintained since it entered an "un-maintained" status in March 2018. Puppeteer, on the other hand, is actively maintained by the Chrome team and continuously developed with new features and updates. This ensures that Puppeteer users can benefit from ongoing improvements and bug fixes.
API and functionality: PhantomJS provides a simple and straightforward API for automating browser interactions, but its functionality is limited compared to Puppeteer. Puppeteer offers a more extensive and powerful API, allowing users to do more advanced tasks such as handling Chrome DevTools Protocol, accessing network activity, and fine-grained control over the browser.
Debugging capabilities: Puppeteer provides better debugging capabilities compared to PhantomJS. With Puppeteer, you can easily debug your code using the Chrome DevTools interface, inspect DOM elements, set breakpoints, and analyze network traffic. Such debugging features are not available or more limited in PhantomJS.
Community and resources: Puppeteer has a larger user community and more available online resources compared to PhantomJS. This means there are more tutorials, sample codes, and support forums available for Puppeteer users, making it easier to find help and solve issues when using Puppeteer.
Integration with other tools and frameworks: Puppeteer has better integration with other tools and frameworks, especially in the Node.js ecosystem. It can be easily combined with testing frameworks like Jest or Mocha, headless testing libraries like Playwright, and various other JavaScript libraries. PhantomJS, being an older tool, may have limitations or compatibility issues with newer frameworks and libraries.
Summary
In summary, the key differences between PhantomJS and Puppeteer lie in their execution environment, maintenance and support, API and functionality, debugging capabilities, community and resources, and integration with other tools and frameworks. Puppeteer offers a more modern and feature-rich experience with better support and extensive functionality, making it a preferred choice for automating web browser interactions.
I am using Node 12 for server scripting and have a function to generate PDF and send it to a browser. Currently, we are using PhantomJS to generate a PDF. Some web post shows that we can achieve PDF generation using Puppeteer. I was a bit confused. Should we move to puppeteerJS? Which one is better with NodeJS for generating PDF?
You better go with puppeteer. It is basically chrome automation tool, written in nodejs. So what you get is PDF, generated by chrome itself. I guess there is hardly better PDF generation tool for the web. Phantomjs is already more or less outdated as technology. It uses some old webkit port that's quite behind in terms of standards and features. It can be replaced with puppeteer for every single task.
I suggest puppeteer to go for. It is simple and easy to set up. Only limitaiton is it can be used only for chrome browser and currently they are looking into expanding into FF. The next thing is Playwright which is just a scale up of Puppeteer. It supports cross browsers.
