X-RAY
The next web scraper, see through the <html> noise
Supports strings, arrays, arrays of objects, and nested object structures. The schema is not tied to the structure of the page you're scraping, allowing you to pull the data in the structure of your choosing. The API is entirely composable, giving you great flexibility in how you scrape each page. Paginate through websites, scraping each page. X-ray also supports a request delay and a pagination limit. Scraped pages can be streamed to a file, so if there's an error on one page, you won't lose what you've already scraped. Start on one page and move to the next easily. The flow is predictable, following a breadth-first crawl through each of the pages. X-ray has support for concurrency, throttles, delays, timeouts and limits to help you scrape any page responsibly. Swap in different scrapers depending on your needs. Currently supports HTTP and PhantomJS driver drivers. In the future, I'd like to see a Tor driver for requesting pages through the Tor network. -

JSSoup
JavaScript + BeautifulSoup = JSSoup
I'm a fan of Python library BeautifulSoup. It's feature-rich and very easy to use. But when I am working on a small react-native project, and I tried to find a HTML parser library like BeautifulSoup, I failed. So I want to write a HTML parser library that can be so easy to use just like BeautifulSoup in Javascript. JSSoup uses tautologistics/node-htmlparser as HTML dom parser, and creates a series of BeautifulSoup like API on top of it. JSSoup supports both node and react-native. JSSoup tries to use the same interfaces as BeautifulSoup so BeautifulSoup user can use JSSoup seamlessly. However, JSSoup uses Javascript's camelCase naming style instead of Python's underscore naming style. -

Maxun
Small event-delegation library for decoupling event binding and handli
Maxun named JsAction by Google serves as a lightweight event delegation library built in JavaScript. It allows developers to separate the logic of binding events from the code that handles those events, helping to keep DOM event wiring cleaner and more maintainable. It is archived and marked as read-only, indicating that the project is no longer actively maintained or intended for production use. The README states that ongoing development has migrated into a larger framework under the Angular project. It includes modules for dispatching events, for capturing native events, for custom event details, and for action flows. Because it is purely JavaScript (and uses HTML for test harnesses), it is suited for web browsers and front-end use. Although deprecated, it can still serve as a reference for how to architect event delegation and binding abstractions. -
