Webpack-dev-server 每次更改后都会发出所有 block

Question

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

这是一个例子:

     + 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，其余的仍然被发出，并且这个变化花了整整2.4秒。

这是为什么呢？我是否缺少 webpack 的某些设置？

当我运行 webpack --watch 并进行更改时，只会发出正确的 block 。所以，我知道这一定是我遗漏的一些小东西。

尝试在 stats 对象中添加 chunks:false 来解决这个问题。引用: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:无、仅错误、最小、正常、详细，否则您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
}
