react-favicon

Control the favicon from a React app

Version 2.x

The major version bump from 1.0.1 to 2.x versions does not include any API changes. The version bump was made because the build and release system was reworked from scratch, also the component was converted to use React's functional component API. Please report bugs if you encounter any.
