React Link Preview

Forked from react-link-preview.

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

Demo

How to use

Install the package:

yarn add @metahkg/react-link-preview

npm install @metahkg/react-link-preview

Import and render the preview:

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

const Home = () => {
  return (
    <LinkPreview
      url='https://www.youtube.com/watch?v=dQw4w9WgXcQ'
      proxyLink='https://rlp.metahkg.org'
      imageProxy='https://i.metahkg.org'
      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.

Important

This package uses a proxy 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.

Recommended workflow (for production)

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

API (Available props)

You can pass the following props to the LinkPreview component.

url (string)

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

proxyLink (string)

The URL of your proxy. e.g. https://rlp.metahkg.org

fetcher? (function)

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 fetcher function returns a Promise that resolves to an object with the above structure.
