spin.js is a dependency-free JavaScript/CSS library that dynamically creates animated spinning activity indicators as a resolution-independent replacement for loading GIFs. It is highly configurable, uses CSS keyframe animations, and ships as a native ES6 module with TypeScript definitions.
Use cases
- show a loading spinner while fetching data
- replace animated loading GIFs with resolution-independent indicators
- add a customizable activity indicator to a web app
- display a spinner during long-running frontend operations
- create CSS-based loading animations without images
When to choose
- you need a lightweight, zero-dependency loading spinner for the browser
- you want a resolution-independent alternative to loading GIFs
- you need broad browser compatibility with configurable spinner options
When to avoid
- your framework already provides built-in loading/spinner components
- you need complex animated illustrations rather than a simple spinner
- you are building a non-web platform like native mobile or desktop
