React-hint is a small tooltip component for React which is developed with simplicity and performance in mind. It also plays nicely with Preact and Inferno. You don't need to include ReactHint in every component which uses tooltips, just include it once in the topmost container component. In case you need to define multiple instances of ReactHint, you can customise the attribute name per instance. ReactHint also supports custom tooltip content with attached event handlers by overriding the content renderer and returning a react node.
