Declarative routing for React web applications

Last verified Sep 9, 2026 against react-router-dom@7.18.3.

react-router-dom publishes both a CommonJS entry and a native ESM entry (ESM added in 7.0.0). require("react-router-dom") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=20.0.0. import "react-router-dom" works alongside it.

## What to do

1. Nothing to change. require("react-router-dom") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=20.0.0. import * as reactRouterDom from "react-router-dom" works alongside it; use named imports for what the ESM entry exports.
2. TypeScript: types are bundled; install nothing extra.
