## What it is
Universal Router is a small, middleware-style routing library for isomorphic JavaScript applications, usable on both client and server. Routes are plain JavaScript objects with path, action, and children properties, and it works with any framework such as React or Vue.

## Use cases
- route urls in a single-page app
- share routing logic between server and client
- add routing to a react or vue app without a framework-specific router
- handle nested routes with middleware-style actions
- render pages server-side based on url path
- build a lightweight spa router with plain object routes

## When to choose
- you want a tiny, framework-agnostic router for client and/or server
- you prefer express/koa-style middleware routing
- you need full control over route matching and history handling

## When to avoid
- you need a batteries-included router with data loading, code splitting, and scroll restoration built in
- you want deep framework integration like react-router or vue-router provide
