## What it is
Autosize is a small, stand-alone JavaScript library that automatically adjusts the height of textarea elements to fit their text content. It works with single elements, NodeLists, or jQuery collections and provides update/destroy methods and lifecycle events.

## Use cases
- make textareas grow automatically as the user types
- auto-resize comment or message input boxes
- fit textarea height to content after setting value programmatically
- avoid scrollbars in multi-line form fields
- recalculate textarea height after layout changes

## When to choose
- you need a tiny dependency-free script for auto-growing textareas
- you want broad browser support including older IE
- you use jQuery or plain DOM and need simple integration

## When to avoid
- you need a full form or UI framework with richer input components
- you need contenteditable-based auto-growing inputs rather than textareas
- you require active development and frequent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, form-handling
- domain: web-development, frontend
- platform: browser, cross-platform
- tags: textarea, auto-resize, javascript, form-ui, standalone-script
