📦 plugin-ideal-image

Docusaurus Plugin to generate an almost ideal image (responsive, lazy-loading, and low quality placeholder).

信息

By default, the plugin is inactive in development so you could always view full-scale images. If you want to debug the ideal image behavior, you could set the disableInDev option to false.

Installation

npm install --save @docusaurus/plugin-ideal-image

用法

该插件仅支持 PNG 和 JPG 格式。

import Image from '@theme/IdealImage';
import thumbnail from './path/to/img.png';

// your React code
<Image img={thumbnail} />

// or
<Image img={require('./path/to/img.png')} />
