Ensure that an alternative indication of state is also provided. For instance, you can include a hint about state in the form control's text itself (as is the case in the following code example), include a Glyphicon (with appropriate alternative text using the .sr-only class - see the Glyphicon examples), or by providing an additional help text block. Specifically for assistive technologies, invalid form controls can also be assigned an aria-invalid="true" attribute.

While there are various packages you can use to install Boostrap in React, the two most popular include react-bootstrap and reactstrap. Both packages are great choices for using Bootstrap with React apps and share very similar characteristics.
The reactstrap package is quite similar to react-bootstrap, with minor differences in things such as component and prop names. However, react-bootstrap is a little older than reactstrap, which may have contributed to its wider adoption range.
When comparing both code files from the reactsrap and react-bootstrap examples, particularly the action that triggers our dropdown toggle, we can see that reactstrap leverages React Hooks to use React features more, while react-bootstrap relies more on component properties.
In this tutorial, we explored a few different ways in which we can integrate Bootstrap with our React apps. We have also seen how we can use two of the most popular React Bootstrap libraries, namely react-bootstrap and reactstrap.
We have only used a few Bootstrap components in this tutorial, such as alert, badge, dropdown, navbar, nav, form, button, card, etc. There is still a couple of Bootstrap components you can experiment with, such as tables, modals, tooltips, carousel, jumbotron, pagination, tabs, etc.
