Heavily inspired by React Motion. The <Transition> component will proxy props to a single functional child. When Transition receives new props it will interpolate values on each animation frame until complete or interrupted.

The props object can be any object permitted by d3.interpolateObject. In practice this allows for transitions of numbers, arrays, colors (as understood by CSS) and much more.

Install react-prop-transition using npm.

npm install react-prop-transition --save

import Transition from 'react-prop-transition';

<Transition props={{number: 0}}
            duration={400}
            easing="cubic" >
  {(props) => <span>{props.number}</span>}
</Transition>
