ReactBootstrap

ReactBootstrap, commonly referred to as React-Bootstrap, is an open-source library that provides Bootstrap-styled components for React applications. It offers a set of React components that mirror Bootstrap components, enabling developers to build user interfaces using Bootstrap’s look and feel without depending on Bootstrap’s JavaScript or jQuery. The library encapsulates Bootstrap’s interactive behaviors inside React components, handling state and events through React.

ReactBootstrap is designed to work with Bootstrap CSS. Developers install the library via npm, along with the Bootstrap CSS package, for example npm install react-bootstrap bootstrap, then include the Bootstrap stylesheet in the app. Components such as Button, Card, Navbar, Modal, Form, Alert, Carousel, and Table are provided. Components are composed via props and children; variants, sizes, and responsive utilities align with Bootstrap’s system.

Usage is typically through named imports, for instance import Button from 'react-bootstrap/Button', then use <Button variant="primary">Submit</Button>. The library emphasizes a declarative React API, with components controlling visibility, animations, and Bootstrap behaviors such as dropdowns, modals, tooltips, and collapse. It aims to integrate Bootstrap’s design system with React’s component model while avoiding direct manipulation of the DOM.

ReactBootstrap supports React 16.8+ and Bootstrap 4 or 5 in different release lines, with versioning tied to Bootstrap major versions. It is MIT-licensed and widely used in React projects that want Bootstrap styling without jQuery. The project is maintained by the core team and community contributors, and it emphasizes accessibility considerations and consistent theming with Bootstrap.
