📦 plugin-ideal-image

生成近乎理想的图像的 Docusaurus 插件（响应式、懒加载及低像素占位图）。

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

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

Yarn

yarn add @docusaurus/plugin-ideal-image

pnpm

pnpm add @docusaurus/plugin-ideal-image

Usage

此插件仅支持 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')} />

Configuration

接受的字段：

选项	类型	默认值	描述
name	string	ideal-img/[name].[hash:hex:7].[width].[ext]	输出文件的文件名模板。
sizes	number[]	original size	指定你想使用的所有宽度。 如果指定尺寸超过了原始图像宽度，则使用后者（即图像不会被放大）。
size	number	original size	指定你想使用的唯一宽度。如果指定尺寸超过了原始图像宽度，则使用后者（即图像不会被放大）。
min	number	undefined	As an alternative to manually specifying sizes, you can specify min, max and steps, and the sizes will be generated for you.
max	number	undefined	See min above
steps	number	4	Configure the number of images generated between min and max (inclusive)
quality	number	85	JPEG 压缩质量。
disableInDev	boolean	true	You can test ideal image behavior in dev mode by setting this to false. Tip: use network throttling in your browser to simulate slow networks.

Example configuration

这是一个示例配置：

docusaurus.config.js

module.exports = {
  plugins: [
    [
      '@docusaurus/plugin-ideal-image',
      {
        quality: 70,
        max: 1030, // max resized image's size.
        min: 640, // min resized image's size. if original is lower, use that size.
        steps: 2, // the max number of images generated between min and max (inclusive)
        disableInDev: false,
      },
    ],
  ],
};
