remix-run/react-router

The repository distributes a routing engine and framework tooling rather than one deployed application. Browser history, React rendering, Fetch-based server handling, and Vite compilation form distinct boundaries. Persistence is supplied through session strategies rather than a central database. The inspected configuration establishes pnpm, Jest, Playwright, and package-specific builds.

• The root workspace builds package projects and discovers Jest projects under packages/*; packageManager is pnpm@11.7.0.
  package.json#L5-48
• react-router exposes separate root, DOM, route-pattern, and React server conditional entrypoints.
  packages/react-router/package.json#L22-70
• createRouter owns route normalization, an ID-keyed manifest, DataRoutes, and the selected data strategy.
  packages/react-router/lib/router/router.ts#L1081-1100
• createBrowserRouter adapts browser history, hydration data, context, instrumentation, and route discovery into the shared engine.
  packages/react-router/lib/dom/lib.tsx#L647-664
• @react-router/dev publishes configuration, route helpers, Vite integration, and the react-router CLI.
  packages/react-router-dev/package.json#L23-54
• The server runtime builds a static handler from compiled routes and dispatches requests using Fetch Request/Response interfaces.
  packages/react-router/lib/server-runtime/server.ts#L60-83packages/react-router/lib/server-runtime/server.ts#L215-264
• Express and Cloudflare adapters bridge platform context into the same core request handler.

• Session persistence supports strategy callbacks, whole-cookie storage, and a Node filesystem implementation.

• The RSC framework playground combines unstable_reactRouterRSC, React, MDX preprocessing, and @vitejs/plugin-rsc.
  playground/rsc-vite-framework/vite.config.ts#L1-23
• Core package builds use Wireit to run tsdown for ordinary and RSC outputs; published files include dist and documentation.
