remix-run/react-router

React Router — declarative routing for React. The default routing library for React apps; merged with Remix to form a unified routing + framework story.

What it is

A TypeScript routing library for React: route definitions, nested routes, dynamic parameters, navigation hooks. Maintained by Remix Software (now part of Shopify). React Router v7 unified the React Router library + Remix framework into a single package — projects can use it as a library (react-router) or as a framework (react-router-dom + the framework conventions).

Key features

Nested route definitions with shared layouts.
Loaders + actions for data fetching at the route level (framework mode).
Type-safe route params.
Library mode (just routing) or framework mode (data + SSR + nested layouts).
TypeScript-first.
MIT-licensed.

Tech stack

TypeScript primary.
npm package: react-router-dom (or react-router for non-web targets).

When to reach for it

You're building any React app that needs client-side routing.
You want to upgrade from Remix → React Router v7's framework mode.

When not to reach for it

You're on Next.js — Next's built-in routing is the canonical choice.
You want a tiny router — wouter or @tanstack/react-router may fit.

Maturity signal

56k stars, 11k forks, MIT, actively maintained under Remix / Shopify.

Alternatives
