Transforms

forward-ref-to-ref-prop

Converts React.forwardRef components to use ref props:

// Before
const Component = React.forwardRef<HTMLInputElement, Props>((props, ref) => {
  return <input ref={ref} {...props} />;
});

// After
const Component = ({ 
  ref,
  ...props 
}: Props & React.HTMLAttributes<HTMLInputElement> & RefProps) => {
  return <input ref={ref} {...props} />;
};

For detailed documentation on each transform, see the respective files in the transform directory.
