Fight!
Popularity
CasperJS was popular in the past, but it is no longer actively maintained and has been deprecated. Playwright, on the other hand, is a relatively new library but has gained significant popularity due to its powerful features and active development.
Functionality
CasperJS is a testing and scraping framework specifically designed for PhantomJS, a headless browser. It provides a high-level API for automating browser actions. Playwright, on the other hand, is a modern and cross-browser automation library that supports multiple browsers such as Chrome, Firefox, and WebKit. It offers a more comprehensive and up-to-date set of features for browser automation and testing.
Compatibility
CasperJS is tightly coupled with PhantomJS, which is no longer actively maintained. This means that CasperJS may not work well with modern browsers and may have compatibility issues. Playwright, on the other hand, is designed to work with modern browsers and provides consistent and reliable automation across different browser engines.
Developer Experience
Playwright provides a more modern and developer-friendly API compared to CasperJS. It has excellent TypeScript support, provides better documentation, and has a more active community. Playwright also offers powerful debugging capabilities and supports multiple programming languages such as JavaScript, TypeScript, Python, and C#. CasperJS, being deprecated, may lack some of these modern development features.
Maintenance
CasperJS is no longer actively maintained and has been deprecated. This means that it may not receive bug fixes, security updates, or new features. Playwright, on the other hand, is actively developed and maintained by Microsoft, ensuring regular updates, bug fixes, and improvements.
