weex debug src 打包出来的js太大

Time: 52304ms
Asset Size Chunks Chunk Names
component\FillOrder\FillOrderHeader.js 473 kB 50 [emitted] [big] component\FillOrder\FillOrderHeader
ui\OrderDetail.js 3.06 MB 0 [emitted] [big] ui\OrderDetail
ui\FillOrder.js 2.75 MB 2 [emitted] [big] ui\FillOrder
ui\TicketList.js 2.45 MB 3 [emitted] [big] ui\TicketList
ui\TrainNumDetail.js 2.48 MB 4 [emitted] [big] ui\TrainNumDetail
ui\ResignSubmit.js 2.76 MB 5 [emitted] [big] ui\ResignSubmit

如果是用webpack打包，只有几百K，这就造成debug的时候，做一点修改，热更新要重新编译，要将近一分钟，请问是什么原因

@fanlvwen maybe it causes by the source map data, you can compile only one file while your project is too heavy.
