我们在开发一个项目时常会用到一些图标,有些图标在有限的图标库中却是没有,因此少数的图标需要我们去网上查找,或是自定义一些专用的图标。一般很少有图标库满足现实的项目开发,这时将推荐使用 iconify 这个图标库,几乎包含我们常见全部的图标,使用也非常简单。废话不多说咱们开始真刀实战。
引入vite插件
- unplugin-icons
- unplugin-vue-components
- vite-plugin-svg-icons
- @iconify/json
- @iconify/vue
# npm
npm i -D @iconify/json @iconify/vue unplugin-icons vite-plugin-svg-icons unplugin-vue-components
#yarn
yarn add -D @iconify/json @iconify/vue unplugin-icons vite-plugin-svg-icons unplugin-vue-components
#pnpm
pnpm add -D @iconify/json @iconify/vue unplugin-icons vite-plugin-svg-icons unplugin-vue-components
使用方式
第一种:unplugin-icons
配置vite插件:
// 配置图标- unplugin-icons
Icons({
compiler: "vue3",
customCollections: {
["local"]: FileSystemIconLoader(LOCAL_PATH, (svg: string) =>
svg.replace(/^<svg\s/, '<svg width="1em" height="1em" '))
},
scale: 1,
autoInstall: true,
defaultClass: "inline-block"
}),
// 配置unplugin-vue-components
Components({
resolvers: [
IconsResolver({
prefix: "icon",
customCollections: COLLECTION_NAME,
}),
],
}),
- 使用iconify图标作为载体显示:
<!-- 使用图标 -->
<icon-ep-bicycle style="font-size: 30px;color: #0C0C0C;background-color: #efafaf"></icon-ep-bicycle>
效果:
图标解释:
icon 为我们自定义的前缀
ep-bicycle 为图标的名字,可以去iconify查询,将冒号 :更换横杠 - 。
2. 使用本地svg图标作为载体显示
下载svg图标文件,放在项目的 src/assets/icons/svg 目录下
<!-- 使用图标 -->
<icon-local-acrobat class="icons"></icon-local-acrobat>
<icon-local-control-center class="icons"></icon-local-control-center>
<icon-local-setting class="icons"></icon-local-setting>
效果:
图标的样式部分可自行调整,演示的样式是我自定义的
图标解释:
icon-local-acrobat
icon 为我们自定义的前缀
local 为我们自定义的集合容器名,在配置vite时指定的
acrobat 为图标文件的名字
第二种:vite-plugin-svg-icons
配置vite插件
// 配置图标- vite-plugin-svg-icons
createSvgIconsPlugin({
// 指定需要缓存的图标文件夹
iconDirs: [LOCAL_PATH],
// 指定symbolId格式
symbolId: `icon-[dir]-[name]`,
inject: "body-last",
customDomId: "__SVG_ICON_LOCAL__",
})
在main.ts中引入样式
import "virtual:svg-icons-register";
自定义SvgIcon组件方便图标的使用,这里我使用的是jsx的形式定义的组件,用vue定义的组件可以自行参照下面的形式写即可。
import type {CSSProperties, PropType} from "vue";
import {computed, defineComponent} from "vue";
import {Icon} from "@iconify/vue";
// horizontal: 水平翻转 ,vertical:垂直翻转
type FlipType = "horizontal" | "vertical";
// 数字代表旋转角度 0° 90° 180° 270°
type RotateType = 0 | 1 | 2 | 3;
/**
* SvgIcon 组件
* @date 2023/9/26
*/
export default defineComponent({
name: "SvgIcon",
props: {
// 图标名字
icon: {
type: String,
required: true,
default: "",
},
// 是否为本地 svg 图标
isLocal: {
type: Boolean,
default: false,
},
// 图标大小
size: {
type: [Number, String],
default: 14,
},
// 旋转角度
rotate: {
type: Number as PropType<RotateType>,
default: 0,
},
// 图标翻转(水平翻转、垂直翻转)
flip: String as PropType<FlipType>,
// 图标旋转动画效果
spin: {
type: Boolean,
default: false,
},
// 单独图标样式
iconStyle: Object as PropType<CSSProperties>,
// 图标颜色
color: String,
// 点击图标触发事件
onClick: Function as PropType<(e: MouseEvent) => void>,
},
setup(props, {attrs}) {
const bindAttrs = computed<{ class: string; style: string }>(() => ({
class: (attrs.class as string) || "",
style: (attrs.style as string) || "",
}));
const symbolId = () => `#icon-${props.icon}`;
const rotate = [0, 90, 180, 270];
const localIconStyle = {
width: "1em",
height: "1em",
lineHeight: "1em",
fontSize: `${`${props.size}`.replace("px", "")}px`,
animation: props.spin ? "circle 3s infinite linear" : "",
transform: (() => {
const scale = props.flip
? props.flip == "vertical"
? "scaleY(-1)"
: props.flip == "horizontal"
? "scaleX(-1)"
: ""
: "";
return `rotate(${rotate[props.rotate]}deg) ${scale}`;
})(),
};
const iconStyles = {outline: "none", animation: props.spin ? "circle 3s infinite linear" : ""};
return () => (
<b
onClick={e => {
props.onClick?.(e);
}}
class={["inline-block", bindAttrs.value.class, props.onClick ? "cursor-pointer" : ""]}
style={bindAttrs.value.style}
>
{props.isLocal ? (
<svg aria-hidden="true"
style={props.iconStyle ? Object.assign(localIconStyle, props.iconStyle) : localIconStyle}>
<use xlinkHref={symbolId()} fill="currentColor"/>
</svg>
) : (
<Icon
icon={props.icon}
width={props.size}
height={props.size}
rotate={props.rotate}
flip={props.flip}
color={props.color}
style={props.iconStyle ? Object.assign(iconStyles, props.iconStyle) : iconStyles}
/>
)}
</b>
);
},
});
使用iconify图标
<!-- 使用图标 -->
<SvgIcon icon="ep:avatar" size="50" color="#000"></SvgIcon>
使用本地图标
<!-- 使用图标 -->
<SvgIcon icon="setting" size="50" is-local class="icons"></SvgIcon>
区别是使用本地svg图标时需要 isLocal 设置为true,其他的属性可自行摸索,在组件中也有相应的代码注释
