Javascript module that allows to extract URL information from text

Javascript module that allows to extract URL information from text


Allows you to extract information from a URL or parse text and retrieve information from the first available link.

NodeJS support

Library should now work on node environments, thanks to @uriva and @itaibs, I will not rename the library because it may cause confusion for people who try to run in a CORS protected environment (ex. google chrome), since this does not happen for RN that was the original intention of the package.

Getting started

$ 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 a URL or a piece of text that contains a URL), the library will take care of parsing it and returning the info of first valid URL info it finds.

URL parsing is done via: https://gist.github.com/dperini/729294

import LinkPreview from 'react-native-link-preview';


  .then(data => console.debug(data));

LinkPreview.getPreview('This is a text supposed to be parsed and the first link displayed https://www.youtube.com/watch?v=MejbOFk7H6c')
  .then(data => console.debug(data));


Additionally you can pass an options object which should add more functionality to the parsing of the link

Property Name Result
imagesPropertyType (optional) (ex: 'og') Fetches images only with the specified property, meta[property='${imagesPropertyType}:image']
    imagesPropertyType: 'og', // fetches only open-graph images
  .then(data => console.debug(data));


Returns a Promise that resolves with an object describing the provided link.
The info object returned varies depending on the content type (MIME type) returned
in the HTTP response (see below for variations of response). Rejects with an error if response can not be parsed or if there was no URL in the text provided.
