Extract react intl messages

extract-react-intl-messages

This package will generate json or yaml files from a glob. It will generate one file per locale, with the ids of each message defined by the defineMessages function of react-intl. The value of each of these keys will be an empty string, except for your defaultLocale which will be populated with the defaultMessage.
