Warning For ReScript users, we recommend using @rescript/react instead. Before, ReasonReact was designed to be used with BuckleScript and it got packaged into @rescript/react. More context on the move here.

ReasonReact is just React.js under the hood. This makes it super easy to integrate with your current Next.js, Create React App, JavaScript, Flowtype or TypeScript project. Learn more about getting started here

Using Your Favorite Javascript Libraries

The same way that TypeScript has type annotations, we have bindings. Bindings are libraries that allow you to import a popular project (like lodash) or to import your own local file. ReasonReact is in fact an example of a binding!
