> Custom hook to use lazyload easily

## Installation

```

$ npm install use-lazyload-ref

$ yarn add use-lazyload-ref

```

## Usage

To enable lazy loading, simply specify `ref` and `data-src` attributes.

```jsx

import React from 'react'

import useLazyloadRef from 'use-lazyload-ref'

const Component = ({ url }) => {

  const [ref, hasLoaded] = useLazyloadRef()

  return (

    


      {hasLoaded || }

      

      {/* */}

      {/* */}

      {/* */}

      {/* 
*/}

    

  )

}

```


## API

### `useLazyloadRef: () => [(node: HTMLElement | null) => void, boolean]`

Custom hook.

In addition to `src` in `audio`, `iframe`, `img` and `video`, CSS property `background-image` can be lazy loaded.

```jsx

const [ref, hasLoaded] = useLazyloadRef()

```

`useLazyloadRef` returns a callback ref function and a load state.

- `ref`: Initialize observer for lazyload.

- `hasLoaded`: Default is false. Turn true if the source has finished loading.
