## What it is
smoothState.js is a jQuery plugin that progressively enhances page loads to provide smooth, controlled page transitions using pushState. It gracefully degrades in browsers lacking required features, simply fading out and never running.

## Use cases
- add smooth page transitions to a multi-page website
- make traditional server-rendered pages feel like a single-page app
- implement contextual or anchor-based transition animations between pages
- avoid full page reload flicker on navigation
- progressively enhance navigation for browsers that support pushState

## When to choose
- you have an existing jQuery-based multi-page site and want fluid page transitions without a full SPA rewrite
- you want progressive enhancement that degrades gracefully on older browsers
- you need lightweight AJAX page swapping with transition control

## When to avoid
- you are building a modern SPA with React, Vue, or similar frameworks that handle routing and transitions natively
- your project does not use jQuery
- you need active maintenance and ongoing updates for a new project

## Facets
- artifact type: plugin
- maturity: maintenance
