## What it is
A standalone vanilla JavaScript module that enables fast AJAX navigation on any website using XMLHttpRequest and pushState, avoiding full page reloads. It swaps page content in place while updating the URL and browser history, with graceful fallback for unsupported browsers.

## Use cases
- make a server-rendered website feel like a single-page app
- avoid full page reloads when navigating between pages
- speed up browsing for users on low-bandwidth connections
- add smooth CSS transitions between page loads
- preserve JS/CSS state across page navigations
- replace jQuery-pjax without a jQuery dependency

## When to choose
- you have a traditional multi-page (server-rendered or static) site and want app-like navigation
- you want a tiny (~6kb) dependency-free solution
- you need multi-container swapping and full history support

## When to avoid
- you are already building an SPA with a frontend framework
- you need SEO-critical dynamic rendering beyond meta updates
- you must support very old browsers without pushState

## Facets
- artifact type: library
- maturity: maintenance
- function: http-client, routing, animation
- domain: web-development, frontend
- platform: browser
- tags: pjax, pushstate, ajax-navigation, vanilla-js, page-transitions, web-server
