# 설치 가이드

1. 코드 내려받기

git clone https://github.com/sergiodxa/react-lazy-image

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd react-lazy-image

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Node.js

쉬움 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Node.js npm 명령어를 쓰려면 Node.js가 설치되어 있어야 합니다. LTS(장기지원) 버전을 추천합니다.

npm i -S react-lazy-image

이 명령어를 터미널에 그대로 입력해 실행하세요.

✅ 명령어 실행 후 터미널에 나타나는 주소(보통 http://localhost:3000 형태)를 브라우저에서 열어보세요.

이 레포의 README에 적힌 실제 명령어를 그대로 가져왔습니다.

# react-lazy-image

Component to render images and lazyload them if are in the viewport (or near to them).

This component extends from `React.PureComponent` so it needs React.js v15.3.0 or superior.

## Installation
```bash
npm i -S react-lazy-image
```

## Usage example
```jsx
import Image from 'react-lazy-image';

const image = <Image source="https://placekitten.com/200/300" />;
```

## API

### `onLayout({ element: Object }): void`
Called everytime the component is rendered or updated. Default: `() => {}`.

### `onError({ element: Object, error: Error }): void`
Called if the request to load the image failed. Default: `() => {}`.

### `onLoad({ element: Object }): void`
Called after the load ended (either successfully or not). Default: `() => {}`.

### `onLoadEnd({ element: Object }): void`
Called after the load ended successfully. Default: `() => {}`.

### `onLoadStart({ element: Object }): void`
Called when the request started. Default: `() => {}`.

### `onAbort({ element: Object }): void`
Called if the load of the image was aborted. Default: `() => {}`.

### `onProgress({ element: Object }): void`
Called everytime the AJAX progress event is dispatched. Default: `() => {}`.

### `offset: ?number`
Set the amount of pixel near the viewport the component should be to start the image load. Default: `0`.

### `source: string`
The image source path to load.

### `defaultSource: ?string`
The default image source path or base64. If isn't defined then it uses a SVG animated spinner.

### `type: ?string`
The format type of the image (`png`, `svg+xml`, `jpg` or `gif`). Default: `*`.

### `minLoaded: ?number`
The minimum download percentaje to avoid aborting the request if the image leaves the viewport. Default: `50`.

## Common `img` attributes
This component allow the usage of common `img` attributes like `alt`, `width`, `className`, etc. So you can use it as a normal `img` tag, just change `src` to `source` and (if you want to) add the other optional props.
