Compare Polymer vs. Semantic UI React

The Polymer library offers a robust set of functionalities for developing custom elements, streamlining the process to ensure they behave like standard DOM elements. Just like conventional DOM elements, Polymer elements can be created through a constructor or by utilizing document creation methods, and they can be configured via attributes or properties. Each instance can contain an internal DOM, adapt to changes in properties and attributes, and receive styling both from internal defaults and external sources, all while responding to methods that alter their internal state. When you register a custom element, you link a class to a specific custom element name, and the element includes lifecycle callbacks to effectively manage its various stages. Additionally, Polymer facilitates property declarations, allowing for seamless integration of your element's property API with the Polymer data system. By employing Shadow DOM, your element gains a locally scoped and encapsulated DOM tree, and Polymer can automatically generate and fill a shadow tree for your element derived from a DOM template, enhancing the modularity and reusability of your code. This combination of features not only simplifies the creation of custom elements but also ensures they integrate smoothly into the wider ecosystem of web components.

Semantic 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.
