A React component that renders beautiful, fully-customizable link previews.

Demo

Install the package:

yarn add @dhaiwat10/react-link-preview

npm install @dhaiwat10/react-link-preview

Import and render the preview:

import { LinkPreview } from '@dhaiwat10/react-link-preview';

const Home = () => {
  return <LinkPreview url='https://www.youtube.com/watch?v=dQw4w9WgXcQ' width='400px' />;
};

If the component renders nothing, it means that no metadata could be scraped for the URL. Provide a fallback component if you don't want to render null.

This package uses a Heroku proxy (open-source) to get around CORS issues. The public proxy receives a lot of traffic (+ there is a rate limit) and is not recommended for production use.

• Please fork the proxy repo and host your own copy of it.
• You can then use the customFetcher prop to pass a fetcher function that fetches data from your proxy. The LinkPreview will now use your proxy as the data source. More details below.

You can pass the following props to the LinkPreview component.

The URL for which you want to generate the link preview.

A function that takes in a url & fetches data from a proxy/server. The function should return a Promise that resolves to an object with the following structure:

{
  title: string | null;
  description: string | null;
  image: string | null;
  siteName: string | null;
  hostname: string | null;
}

You can use any data-source as you like as long as the customFetcher function returns a Promise that resolves to an object with the above structure.

Example

A fallback component which will be rendered if a link preview could not be generated.

A fallback image src/URL which will be used if there was no image found for the URL.

The src that will be used for the image regardless of what the data source returns.

Whether you want to display the default loading skeleton or not.

Custom loader that will be displayed in place of the default loader.

Length of the description in the card. (number of characters)

Border radius of the card.
