1、安装依赖包:
npm install svg-sprite-loader --save-dev
2、新建assets/icons/svg中放置svg图片和index.js文件 svgo.yml文件
index.js
import Vue from 'vue'
import SvgIcon from '@/components/SvgIcon'// svg component// register globally
Vue.component('svg-icon', SvgIcon)const req = require.context('./svg', false, /\.svg$/)
const requireAll = requireContext => requireContext.keys().map(requireContext)
requireAll(req)
svgo.yml:
# replace default config# multipass: true
# full: trueplugins:# - name## or:# - name: false# - name: true## or:# - name:# param1: 1# param2: 2- removeAttrs:attrs:- 'fill'- 'fill-rule'
3、utils中新建validate.js
代码如下:
/*** @param {string} path* @returns {Boolean}*/
export function isExternal(path) {return /^(https?:|mailto:|tel:)/.test(path)}/*** @param {string} str* @returns {Boolean}*/export function validUsername(str) {const valid_map = ['admin', 'editor']return valid_map.indexOf(str.trim()) >= 0}/*** @param {string} url* @returns {Boolean}*/export function validURL(url) {const reg = /^(https?|ftp):\/\/([a-zA-Z0-9.-]+(:[a-zA-Z0-9.&%$-]+)*@)*((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[1-9][0-9]?)(\.(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[1-9]?[0-9])){3}|([a-zA-Z0-9-]+\.)*[a-zA-Z0-9-]+\.(com|edu|gov|int|mil|net|org|biz|arpa|info|name|pro|aero|coop|museum|[a-zA-Z]{2}))(:[0-9]+)*(\/($|[a-zA-Z0-9.,?'\\+&%$#=~_-]+))*$/return reg.test(url)}/*** @param {string} str* @returns {Boolean}*/export function validLowerCase(str) {const reg = /^[a-z]+$/return reg.test(str)}/*** @param {string} str* @returns {Boolean}*/export function validUpperCase(str) {const reg = /^[A-Z]+$/return reg.test(str)}/*** @param {string} str* @returns {Boolean}*/export function validAlphabets(str) {const reg = /^[A-Za-z]+$/return reg.test(str)}/*** @param {string} email* @returns {Boolean}*/export function validEmail(email) {const reg = /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/return reg.test(email)}/*** @param {string} str* @returns {Boolean}*/export function isString(str) {if (typeof str === 'string' || str instanceof String) {return true}return false}/*** @param {Array} arg* @returns {Boolean}*/export function isArray(arg) {if (typeof Array.isArray === 'undefined') {return Object.prototype.toString.call(arg) === '[object Array]'}return Array.isArray(arg)}
4、在components中新建文件夹
index.vue代码如下:
<template><div v-if="isExternal" :style="styleExternalIcon" class="svg-external-icon svg-icon" v-on="$listeners" /><svg v-else :class="svgClass" aria-hidden="true" v-on="$listeners"><use :xlink:href="iconName" /></svg></template><script>import { isExternal } from '@/utils/validate'export default {name: 'SvgIcon',props: {iconClass: {type: String,required: true},className: {type: String,default: ''}},computed: {isExternal() {return isExternal(this.iconClass)},iconName() {return `#icon-${this.iconClass}`},svgClass() {if (this.className) {return 'svg-icon ' + this.className} else {return 'svg-icon'}},styleExternalIcon() {return {mask: `url(${this.iconClass}) no-repeat 50% 50%`,'-webkit-mask': `url(${this.iconClass}) no-repeat 50% 50%`}}}}</script><style scoped>.svg-icon {width: 1em;height: 1em;vertical-align: -0.15em;fill: currentColor;overflow: hidden;}.svg-external-icon {background-color: currentColor;mask-size: cover!important;display: inline-block;}</style>
5、vue.config.js配置如下:
'use strict'
const path = require('path')function resolve(dir) {return path.join(__dirname, dir)
}const name = '管理系统' // 标题const port = process.env.port || process.env.npm_config_port || 80 // 端口// vue.config.js 配置说明
//官方vue.config.js 参考文档 https://cli.vuejs.org/zh/config/#css-loaderoptions
// 这里只列一部分,具体配置参考文档
module.exports = {// 部署生产环境和开发环境下的URL。// 默认情况下,Vue CLI 会假设你的应用是被部署在一个域名的根路径上// 例如 https://www.xxx.com/。如果应用被部署在一个子路径上,你就需要用这个选项指定这个子路径。例如,如果你的应用被部署在 https://www.xxx.com/admin/,则设置 baseUrl 为 /admin/。publicPath: process.env.NODE_ENV === "production" ? "/" : "/",// 在npm run build 或 yarn build 时 ,生成文件的目录名称(要和baseUrl的生产环境路径一致)(默认dist)outputDir: 'dist',// 用于放置生成的静态资源 (js、css、img、fonts) 的;(项目打包之后,静态资源会放在这个文件夹下)assetsDir: 'static',// 是否开启eslint保存检测,有效值:ture | false | 'error'lintOnSave: process.env.NODE_ENV === 'development',// 如果你不需要生产环境的 source map,可以将其设置为 false 以加速生产环境构建。productionSourceMap: false,// webpack-dev-server 相关配置devServer: {host: '0.0.0.0',port: port,open: true,proxy: {// detail: https://cli.vuejs.org/config/#devserver-proxy[process.env.VUE_APP_BASE_API]: {target: `http://localhost:8080`,changeOrigin: true,pathRewrite: {['^' + process.env.VUE_APP_BASE_API]: ''}}},// disableHostCheck: true},configureWebpack: {name: name,resolve: {alias: {'@': resolve('src')}}},chainWebpack(config) {config.plugins.delete('preload') // TODO: need testconfig.plugins.delete('prefetch') // TODO: need test// set svg-sprite-loaderconfig.module.rule('svg').exclude.add(resolve('src/assets/icons')).end()config.module.rule('icons').test(/\.svg$/).include.add(resolve('src/assets/icons')).end().use('svg-sprite-loader').loader('svg-sprite-loader').options({symbolId: 'icon-[name]'}).end()config.when(process.env.NODE_ENV !== 'development',config => {config.plugin('ScriptExtHtmlWebpackPlugin').after('html').use('script-ext-html-webpack-plugin', [{// `runtime` must same as runtimeChunk name. default is `runtime`inline: /runtime\..*\.js$/}]).end()config.optimization.splitChunks({chunks: 'all',cacheGroups: {libs: {name: 'chunk-libs',test: /[\\/]node_modules[\\/]/,priority: 10,chunks: 'initial' // only package third parties that are initially dependent},elementUI: {name: 'chunk-elementUI', // split elementUI into a single packagepriority: 20, // the weight needs to be larger than libs and app or it will be packaged into libs or apptest: /[\\/]node_modules[\\/]_?element-ui(.*)/ // in order to adapt to cnpm},commons: {name: 'chunk-commons',test: resolve('src/components'), // can customize your rulesminChunks: 3, // minimum common numberpriority: 5,reuseExistingChunk: true}}})config.optimization.runtimeChunk('single'),{from: path.resolve(__dirname, './public/robots.txt'), //防爬虫文件to: './', //到根目录下}})}
}
6、页面中使用
<svg-icon icon-class="home"/> //home是svg图片的名字
7、修改颜色:svg图片中的fill删掉
并且设置颜色:
.svg-icon {fill: #315efb;}
最后效果:
