Allows to extract information from an URL or parse a text and retrieve information from the first available link.
$ npm install -S react-native-link-preview
Library exposes just one method: getPreview, you have to pass a string (doesn't matter if it is just an URL or a piece of text that contains an URL), the library will take care of parsing it and returning the info of first valid URL info it finds.
1.0.x versions: The parsing is done automatically via Autolinker, if you have problems getting your URL recognized you can dig their documentation for a valid regex.
1.1.x versions: Parsing is simplified to avoid dependency on Autolinker and having to double check for malformed URLs, basically: string is splitted by space characters and each token is tested against propper regex (https://gist.github.com/dperini/729294), if you have any problems with this please create a ticket, haven't tested all possible cases where this could fail.
