## What it is
Router5 is a framework- and view-library-agnostic JavaScript router that processes routing instructions and emits state updates, working both client-side and server-side. It is modular and extensible via plugins, with integrations for React, Redux, and observable libraries.

## Use cases
- route a single-page application without coupling to a view framework
- use the same router on client and server for universal/isomorphic apps
- integrate routing state with Redux or RxJS observables
- control navigation transitions and prevent navigation with middleware
- build a React app with hooks-based routing via react-router5

## When to choose
- you want a view-agnostic router with clear separation of routing state from UI
- you need universal (client and server) routing
- you want fine-grained control over transitions, middleware, and plugins
- you use React, Redux, or observables and want first-class integration

## When to avoid
- you want a batteries-included router tightly integrated with a mainstream framework like React Router or Vue Router
- you need a router with active ongoing development and frequent releases
- you prefer file-based or convention-over-configuration routing

## Facets
- artifact type: library
- maturity: maintenance
- function: routing, middleware, state-management
- domain: web-development, frontend
- platform: browser, cross-platform
- tags: universal-router, framework-agnostic, reactive, plugin-system, typescript, javascript, nodejs
