parsel
Python Software Foundation
FreeParsel is a Python library licensed under BSD that facilitates the extraction and removal of data from HTML and XML documents using XPath and CSS selectors, with the option to integrate regular expressions. To begin, you create a selector object for the HTML or XML content you wish to analyze. After that, you can utilize either CSS or XPath expressions to target specific elements. CSS serves as a styling language for HTML, defining selectors that link styles to designated HTML elements, while XPath is utilized for selecting nodes within XML documents and can also be applied to HTML. Although both CSS and XPath can be used, CSS tends to offer greater readability, whereas XPath provides capabilities that may not be achievable through CSS alone. Built on top of lxml, parsel selectors incorporate some EXSLT extensions and come with pre-registered namespaces available for use in XPath queries. Furthermore, parsel selectors allow for the chaining of selectors, enabling users to primarily select by class using CSS and seamlessly transition to XPath when the situation demands it, enhancing flexibility in data extraction tasks. This dual capability makes parsel a powerful tool for developers working with web data. -

waiting
Python Software Foundation
FreeWaiting is a compact library designed to facilitate the process of waiting for specific conditions to be met. It fundamentally pauses execution until a designated function returns True, offering various operational modes. Additionally, Waiting is designed to work seamlessly with flux for simulating timelines. The simplest way to utilize it is by providing a function to monitor. It’s straightforward to wait indefinitely; if your predicate yields a value, that value will be returned as the output of wait(). You can also set a timeout, and if this period lapses without the predicate being satisfied, an exception will occur. The library polls the predicate at a default interval of one second, which can be adjusted using the sleep_seconds parameter. When dealing with multiple predicates, Waiting offers two efficient methods for aggregation: any and all. These methods are similar to Python's built-in any() and all(), but they ensure that a predicate is not invoked more than necessary, which is particularly beneficial when working with predicates that are resource-intensive and time-consuming. By streamlining these functions, Waiting enhances both the efficiency and user experience of handling asynchronous operations. -

Semantic UI React
Vercel
Free 1 RatingSemantic UI React serves as the official integration of Semantic UI within the React framework, eliminating the need for jQuery and offering a declarative API along with shorthand properties, sub-components, and an auto-controlled state. Unlike jQuery, which relies on direct manipulation of the DOM, React operates with a virtual DOM that represents the actual DOM in JavaScript. React's approach allows it to apply patch updates to the DOM without directly reading from it, making it impractical to synchronize jQuery's DOM manipulations with React's virtual DOM. Consequently, the functionality provided by jQuery has been completely re-implemented within React. This framework allows users to dictate which HTML tags are rendered or to substitute one component for another seamlessly. Additional properties can be passed to the rendered component, enhancing flexibility and functionality. Augmentation within the framework is particularly beneficial, as it enables the composition of component features and properties without the complication of introducing extra nested components. The use of shorthand props simplifies markup generation, streamlining various use cases. Furthermore, all object properties are automatically spread across child components, enhancing the ease of use and reducing boilerplate code. Overall, Semantic UI React empowers developers with a robust toolset for building user interfaces efficiently. -

FormValidation
FormValidation
$50 one-time paymentStarting from version 1.0.0, the library has been entirely rewritten using Typescript and ES6, eliminating the outdated jQuery plugin. The new architecture is based on plugins, resulting in a streamlined core library. Each file found in the dist/css and dist/js directories is available in two formats: the standard versions with .css and .js extensions, and the optimized versions with .min.css and .min.js extensions. For improved page load times and a better user experience on your production website, it is recommended to implement the minified files. Conversely, during development, utilizing the standard files without the .min suffix facilitates easier debugging and code maintenance. This transition not only enhances performance but also modernizes the overall structure of the library. -
