React Router Server

Server-side rendering library for React Router v4 (version 4.2.3). Provides utilities for SSR including state fetching, code splitting via Webpack 2, and preloading modules. Requires peer dependencies react (^15.3 || ^16), react-dom, and react-router (^4.0). Ships TypeScript types. The project is in maintenance mode and seeking maintainers. Key differentiators: integrates tightly with React Router v4, offers a custom renderToString that returns a promise, and includes a Module component for code splitting.
