What it is

React Router is a multi-strategy routing library for React that supports both framework-mode (full application structure) and library-mode (minimal routing in custom architectures). It handles client-side navigation, server-side rendering (SSR), React Server Components (RSC), and data loading patterns, with support for multiple runtime environments (Node.js, Cloudflare Workers, Architect, Express). Monorepo with packages/react-router/ as the core, containing layered subdirectories: lib/dom/ for browser/hydration logic, lib/rsc/ for React Server Component support, lib/server-runtime/ for isomorphic server utilities (cookies, crypto, headers), lib/router/ for routing logic…

Start here

Read these in order:

• build.utils.ts — Foundation: doesn't import anything internally and is imported by 11 other files. Read first to learn the vocabulary.
• packages/create-react-router/utils.ts — Foundation: imported by 9, no internal dependencies of its own.
• packages/react-router/lib/router/history.ts — Built on the foundation; imported by 22 downstream files.
• packages/react-router-dev/vite/vite.ts — Built on the foundation; imported by 10 downstream files.
• packages/react-router/lib/router/utils.ts — Layer 2 — composes lower-level code into reusable abstractions (imported 41×).

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone the repository and verify manifest before setup:

git clone https://github.com/remix-run/react-router.git
cd react-router

The monorepo uses workspace: dependencies (visible in package.json). Standard monorepo tooling (npm workspaces, pnpm, or yarn) should be used, but verify the repository documentation for the exact package manager before…

Daily commands:

Inferred from package.json: The example integration (integration-rsc-vite-framework) shows:

npm run dev        # Start Vite dev server
npm run build      # Build with Vite (--app flag for full-stack)
npm run start      # Run production server (NODE_ENV=production)
npm run typecheck  # Generate typegen and run TypeScript check

These are specific to the example; verify actual monorepo root for primary development commands.

…shortened for this brief.

Key cautions & unknowns

• 1. Workspace dependencies: The monorepo uses "workspace:*" version resolution; direct npm install may fail—use npm/pnpm workspaces or yarn correctly. 2. RSC + SSR duality: Files like lib/dom/ssr/ and…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
