Spin.js

Spin.js is a lightweight JavaScript library for creating animated loading spinners without requiring images or external assets. The library generates spinners dynamically using CSS and JavaScript, allowing for customizable size, color, speed, and appearance. Spin.js is highly configurable through options that control the number of lines, line length, width, radius, and rotation speed. The library is framework-agnostic and works with vanilla JavaScript or any JavaScript framework including jQuery, React, and Angular. Spin.js produces smooth, hardware-accelerated animations that perform well across different browsers and devices. The library has no dependencies and adds minimal overhead to web applications, typically just a few kilobytes. Spin.js is commonly used in web applications to indicate loading states during AJAX requests, form submissions, or any asynchronous operations where users need visual feedback that processing is occurring.
