webpack4 splitChunks用法？提取？万分感谢

Question

我搭建的是一个单页应用想用webpack4下的splitChunks功能想将node_modules引用的模块比如vue之类的提取放到一个js文件下但是怎么提都提不出来一点反应都没有，这是怎么回事？optimization:{splitChunks:{chunks:'initial',//默认只作用于异步模块，为`all`时对所有模块生效,`initial`对同步模块有效minSize:30000,//合并前模块文件的体积minChunks:1,//最少被引用次数maxAsyncRequests:5,maxInitialRequests:3,automaticNameDelimiter:'~',cacheGroups:{vendors:{test:/node_modules/,minChunks:1,priority:-10},default:{test:/src/,minChunks:2,priority:-20,reuseExistingChunk:true}}}},

Answer 1

splitChunks:{
cacheGroups:{
manifest:{
name:"manifest",
chunks:"initial",
minChunks:2
},
vendor:{
chunks:"all",
test:/[\\/]node_modules[\\/]/,
name:"vendor",
minChunks:1,
maxInitialRequests:5,
minSize:0,
priority:98
}
}
}
},
