## What it is
Director is a tiny, dependency-free URL router for JavaScript that works isomorphically in both the browser (hash-based client-side routing) and Node.js (HTTP and CLI routing). It is part of the Flatiron suite of modules for building apps in Node.js and the browser.

## Use cases
- add client-side hash routing to a single page app
- route HTTP requests in a Node.js server without Express
- route CLI commands and flags in a Node.js script
- share the same routing code between browser and server
- build a router without jQuery or framework dependencies

## When to choose
- you need a minimal, dependency-free router for legacy browser or Node.js projects
- you want one routing library usable on both client and server
- you maintain an older Flatiron-based codebase

## When to avoid
- you are starting a modern SPA — use framework routers like React Router or Vue Router instead
- you need active maintenance, security updates, or modern history-API routing
- you need Express-style middleware ecosystems

## Facets

- function: routing, http-server, cli
- domain: web-development, frontend, backend, developer-tools
