## What it is
Superstatic is an enhanced static file server for Node.js, usable both as a CLI tool and as an API/middleware library. It supports HTML5 pushState apps, clean URLs, custom rewrites, redirects, caching, and JSON-based configuration.

## Use cases
- serve a static site locally during development
- host a single-page app with pushState routing
- strip .html extensions with clean URLs
- configure rewrites and redirects via a JSON file
- use a static server as connect/express middleware

## When to choose
- you need a static server with SPA-friendly rewrites and clean URLs
- you want JSON-configurable static hosting behavior matching Firebase Hosting
- you need an embeddable static server middleware for Node.js

## When to avoid
- you need a full production web server with TLS termination and load balancing
- you are serving a dynamic server-rendered application
- you need a language-agnostic server outside the Node.js ecosystem
