📦 plugin-ideal-image

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

info

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

Este plugin suporta apenas os formatos PNG e JPG.

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

Campos aceitos:

Option	Type	Padrão	Descrição
name	string	ideal-img/[name].[hash:hex:7].[width].[ext]	Filename template for output files.
sizes	number[]	original size	Specify all widths you want to use. Se um tamanho específico exceder a largura da imagem original, este último será usado (ou seja, as imagens não serão dimensionadas).
size	number	original size	Specify one width you want to use; if the specified size exceeds the original image's width, the latter will be used (i.e. images won't be scaled up)
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 compression quality
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

Here's an example configuration:

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,
      },
    ],
  ],
};
