## How to use
**Install the package:**
`yarn add ong-react-link-preview`
`npm install ong-react-link-preview`
**Import and render the preview:**
```js
import { LinkPreview } from 'ong-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`.
## Important
This package uses a Heroku [proxy (open-source)](https://github.com/dhaiwat10/rlp-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](https://github.com/dhaiwat10/rlp-proxy) 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.
## 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.
<hr />
### `customFetcher?` (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:
```js
{
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.
