将第三库分割成多个文件
使用SplitChunksPlugin进行手工分割
splitChunks=[ maxInitialRequest:Infinity, maxSize:0, chunks:'all', cacheGroups:{ antVendor:{ name :'ant-design', test:/[\\/]node_modules[\\/](ant-design-vue)[\\/]/, }, vendor:{ name :'vendor', test:/[\\/]node_modules[\\/](!ant-design-vue)[\\/]/, } } ]
根据文件大小自动分割
splitChunks=[ maxInitialRequest:Infinity, maxSize:300*1024, chunks:'all', cacheGroups:{ antVendor:{ test:/[\\/]node_modules[\\/]/, name(module):{ const packageName=module.context.match(/[\\/]node_modules[\\/](.*?)([\\/]|$)/)[1] return `npm.{packageName.replace('@','')` } } } ]
