svg图标封装

PS:注意如果在iconfont上下载的SVG图标，请把fill="#ffffff"清除掉，不然自定义样式无法作用到图标上。

PS:webpack3及以下和webpack4配置略有不同， webpack4的SVG配置请参考 潘

npm install -g svgo

svgo -f ./src/icons/svg

npm install svg-spribe-loader -D

配置build/webpack.base.conf.js

{

test: /\.svg$/,

loader: 'svg-sprite-loader',

include: [resolve('src/icons')],

options: {

symbolId: 'icon-[name]'

}

},

{

test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,

loader: 'url-loader',

exclude: [resolve('src/icons')],

options: {

limit: 10000,

name: utils.assetsPath('img/[name].[hash:7].[ext]')

}

},
