> react-bootstrap@2.10.10 is a CommonJS package. CommonJS — require() works on every Node.js version we test.

Bootstrap 5 components built with React

Last verified Sep 9, 2026 against react-bootstrap@2.10.10.

react-bootstrap ships CommonJS only. require("react-bootstrap") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "react-bootstrap" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

It also declares a "module" field, so bundlers such as webpack, Vite and esbuild pick up an ESM build for tree-shaking.

## What to do

1. require("react-bootstrap") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun.
2. From ES modules use the default import: import reactBootstrap from "react-bootstrap"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.
