It supports the repositioning of multiple items simultaneously and the use of specific drag handles to restrict which areas of an element trigger a move. Additional capabilities include programmatic sor

nprogress is a lightweight JavaScript UI component and web progress bar library. It provides a minimalist DOM progress indicator used to track the state of asynchronous operations within a browser document. The library allows for the visualization of loading states through a thin progress bar and spinner. It supports progress state management, enabling the bar to be started, stopped, or marked as complete, with support for incremental progress tracking and percentage-based updates. Users can modify the visual style by overriding default CSS or replacing the markup template. The component als

Dva is a state management library and client-side application framework designed for building user interfaces with React and Redux. It functions as an asynchronous logic orchestrator and a single page application router, organizing application data through a structured data flow of reducers, effects, and subscriptions. The framework distinguishes itself through the use of generator functions to manage asynchronous workflows and sequential side effects, keeping these operations separate from synchronous state updates. It implements namespace-based model organization to group business logic and

RequireJS is a JavaScript module loader and dependency manager that implements the Asynchronous Module Definition API. It enables the asynchronous loading of JavaScript files in the browser to prevent page rendering blocks and manages interdependent scripts to avoid global namespace pollution and execution order issues. The project includes a build optimizer that combines and minifies multiple script files into single bundles to reduce network requests. It also provides a mechanism for version management, allowing multiple versions of the same library to coexist on a single page without confl

Toastr is a JavaScript toast notification library and client-side alert manager used to display non-blocking alert messages and system notifications in web browsers. It serves as a frontend notification UI for rendering timed messages that provide real-time visual feedback within web applications. The library includes a notification system that supports right-to-left layout mirroring for internationalized applications. It also features a mechanism to prevent duplicate notifications by matching new content against active alerts to avoid redundant stacking. The system manages notification life

onepage-scroll is a JavaScript library and scroll orchestrator that transforms websites into a series of sections navigated one page at a time. It functions as a single page navigation tool that implements viewport-based section snapping to lock the scroll position to full-screen segments. The library provides a responsive scrolling interface that automatically reverts to standard browser scrolling behavior when the window width drops below a defined threshold. It synchronizes the browser address bar with the current section index as the user navigates through the page. The system includes c

Push.js is a cross-browser JavaScript library for displaying native desktop notifications from web applications. It wraps the divergent browser notification APIs into a single consistent interface, handling permission requests through a promise-based flow and providing graceful fallback when the native Notification API is unavailable. The library distinguishes itself through its event-driven lifecycle hooks, which expose callbacks for notification events such as show, click, close, and error. It also supports programmatic dismissal by returning a notification handle with a close method, and i
