## What it is
Ladda is a JavaScript/CSS library that embeds loading indicators (spinners and progress bars) directly into buttons. It provides immediate visual feedback on actions like form submissions, with multiple animation styles and sizes.

## Use cases
- show a spinner on a submit button while a form posts to the server
- display a progress bar inside a button during a long-running upload
- add loading feedback to buttons in a web app without writing custom CSS animations
- prevent double submissions by visually disabling a button while loading
- customize button loading animations with different styles, sizes, and colors

## When to choose
- you want built-in loading indicators on buttons with minimal setup
- you need multiple animation styles (expand, contract, zoom, slide) out of the box
- you want a lightweight, framework-agnostic vanilla JS solution

## When to avoid
- you use a modern component framework and prefer native loading components or a full UI kit
- you need accessibility features beyond basic button states
- you require active development or frequent updates, as the project is in maintenance mode

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, animation
- domain: frontend, web-development, web-design
- platform: browser, cross-platform
- tags: loading-indicators, buttons, spinners, ux, form-feedback, javascript
