Question

我刚为我们的开发环境实现了热重载。我的javascript被分解成很多块。每次我对文件进行更改时，都会重新提交所有块。我正在运行webpack-dev-server。

以下是一个例子：

Hash: 83298e5f7612c91d96ee

     + 1 hidden modules

     + 216 hidden modules

     + 590 hidden modules
chunk   {13} static/js/music/13.js 1.23 MB {12}
     + 215 hidden modules
chunk   {14} static/js/music/14.js 873 kB {12}
     + 160 hidden modules
chunk   {15} static/js/music/15.js 1.22 MB {12}
     + 212 hidden modules
chunk   {16} static/js/music/bundle4.js (bundle4) 1.87 MB
     + 590 hidden modules
chunk   {17} static/js/music/17.js 566 kB {16}
     + 93 hidden modules
chunk   {18} static/js/music/18.js 474 kB {16}
     + 33 hidden modules
chunk   {19} static/js/music/19.js 486 kB {16}
     + 33 hidden modules
chunk   {20} static/js/music/20.js 955 kB {16}
     + 190 hidden modules
webpack: bundle is now VALID.

如您所见，实际上只构建了mychange.jsx文件。然而，其余的仍然被发射，并且变化花了整整2.4秒。

这是为什么？我错过了webpack的一些设置吗？

当我运行webpack --watch并进行更改时，只会发出正确的块。所以，我知道它一定是我想念的小事。

尝试在stats对象中添加chunks:false解决此问题。参考：https://webpack.github.io/docs/node.js-api.html

devServer: {
    stats: { chunks:false }
}

Here's the relevant code。看起来可接受的预设值是：none，errors-only，minimal，normal，verbose，否则你可以指定自己的对象：

{
    hash: false,
    version: false,
    timings: false,
    assets: false,
    chunks: false,
    modules: false,
    reasons: false,
    children: false,
    source: false,
    errors: false,
    errorDetails: false,
    warnings: false,
    publicPath: false
}

每次更改后，Webpack-dev-server都会发出所有块
