First you need to install react-bootstrap as their documentation.
Basically you'll need to run these commands:
# with npm
npm add react-bootstrap@next bootstrap@5.1.0
# with yarn
yarn add react-bootstrap@next bootstrap@5.1.0Then, you'll need to import bootstrap styles into your app:
// App.js
import "bootstrap/dist/css/bootstrap.min.css";Finally you can install this package running these commands:
# with npm
npm add -D @rescriptbr/react-bootstrap
# with yarn
yarn add -D @rescriptbr/react-bootstrapmodule Form = ReactBootstrap.Form
module Button = ReactBootstrap.Button
module Container = ReactBootstrap.Container
@react.component
let make = () => {
  <Container>
    <Form>
      <Form.Group>
        <Form.Label> {`Email`->React.string} </Form.Label>
        <Form.Control _type="email" />
      </Form.Group>
      <Form.Group>
        <Form.Label> {`Senha`->React.string} </Form.Label>
        <Form.Control _type="password" />
      </Form.Group>
      <Button size=#lg _type=#submit>
        {`Acessar`->React.string}
      </Button>
