Oracle Drags Its Feet in the JavaScript Trademark Dispute
Oracle seeks to dismiss fraud claims in the JavaScript trademark dispute, delaying the case and avoiding questions about its right to the name.
@kwai-explore/picture.vue
Advanced tools
用于展示多种图片格式的 picture 组件。
pnpm install @kwai-explore/picture.vue
建议配合 (vite-plugin-image-presets) 使用
pnpm add -D vite-plugin-image-presets
vite.config.ts
import imagePresets, { formatPreset } from 'vite-plugin-image-presets';
// ...
plugins: [
vue(),
imagePresets({
modern: formatPreset({
formats: {
avif: {},
webp: {},
original: {},
},
loading: 'lazy',
}),
}),
],
根据上面的配置添加类型:
vite-env.d.ts
这里的文档需要换一下:理论上应该标记的是自己生成的类型
declare module '*?preset=modern' {
type SourceOption = {
type: string;
srcset: string;
};
type ImgOption = {
src: string;
// 这下面的属性需要与 vite config 里的 formatPreset 配置同步修改
loading: 'lazy';
};
type PictureOption = [...SourceOption[], ImgOption];
const src: PictureOption;
export default src;
}
Picture 组件接受的属性跟
img
相同,唯一的例外是src
接收一个数组,一个例子是
[{
type: 'image/webp',
srcset: '/assets/logo.ffc730c4.webp 48w, /assets/logo.1f874174.webp 96w',
},
{
type: 'image/jpeg',
srcset: '/assets/logo.063759b1.jpeg 48w, /assets/logo.81d93491.jpeg 96w',
src: '/assets/logo.81d93491.jpeg',
class: 'img thumb',
loading: 'lazy',
]
在我们配置好 vite-plugin-image-presets
之后,可以直接在 import 图片的语句后面加一个 query,产出的数据就是上面需要的格式。
<script setup lang="ts">
import Picture from '@kwai-explore/picture';
import examplePic from './components/example.jpg?preset=modern';
</script>
<template>
<Picture :src="examplePic"></Picture>
</template>
完整支持的属性
interface PictureProp {
src: ImgHTMLAttributes[];
// 默认是empty。 color 会展示一个渐变色块的 loading 效果,加上 fade-in 的加载成功的渐变效果。
placeholder: 'empty' | 'color';
}
'vue/no-restricted-html-elements': [
'warn',
{
element: 'img',
message: 'Prefer use of our @kwai-explore/picture.vue component',
},
],
开发环境(vite dev
) 初次请求图片资源时需要进行格式转换,图片的加载时间比较长。
生产环境(vite build
) 会把需要的图片格式都构建出来。
vue >= 2.7
