在最近的项目里，页面和静态文件并不是很多的情况下，打包后发现产出的静态资源却很大。
1.关掉sourcemap
在config/webpack.config.js文件里，大概30几行的位置添加这样一句代码，这样做的作用是防止线上生成环境将源码一起打包部署。
2.将一些公共的库（比如antd）做一个缓存
splitChunks: {
chunks: ‘all‘,
name: "vender",
cacheGroups: {
vender: {
name: "vendor",
test: /[\\/]node_modules[\\/]/,
chunks: "all",
priority: 10,
enforce: true
},
react: {
name: "react",
test: (module) => /react|redux/.test(module.context),
chunks: "initial",
priority: 11,
enforce: true
},
antd: {
name: "antd",
test: (module) => {
return /ant/.test(module.context);
},
chunks: "initial",
priority: 11,
enforce: true
},
moment: {
name: "moment",
test: (module) => {
return /moment/.test(module.context);
},
chunks: "initial",
priority: 13,
enforce: true
}
}
},
