How can I access a hover state in reactjs?

by

React components expose all the standard Javascript mouse events in their top-level interface. Of course, you can still use :hover in your CSS, and that may be adequate for some of your needs, but for the more advanced behaviors triggered by a hover you’ll need to use the Javascript. So to manage hover interactions, you’ll want to use onMouseEnter and onMouseLeave. You then attach them to handlers in your component like so:

<ReactComponent
    onMouseEnter={() => this.someHandler}
    onMouseLeave={() => this.someOtherHandler}
/>

You’ll then use some combination of state/props to pass changed state or properties down to your child React components.
