带有Lazy-Loaded路由的Angular CLI HMR会重新加载整个内容

Question

(即使使用Angular 7也确认了问题).让我们解决这个问题!

我正在使用HMR设置:https://github.com/angular/angular-cli/wiki/stories-configure-hmr from a ng newbuild build.

如果我更改任何组件并使其延迟加载,角度HMR将热重新加载所有内容,使页面同步更慢.

我知道这是因为它默认设置为console.log每个正在重新加载的模块,当我使用惰性路由时,它会记录所有内容.但是当我将该组件更改为非延迟加载时,它只记录一些小组件.

因此,当我使用HMR和懒惰路由时,我的应用程序需要几秒钟才能刷新.这很烦人.

有没有办法解决？

(懒惰的加载路线是通过这样的方式完成的)

// Main homepage
{
  path: '',
  loadChildren: './public/home/home.module#HomeModule'
},
// ...

(只是一个例子,表明我正在以正确的方式加载)

这里有一些日志记录显示我懒惰加载时会发生什么 home.component.ts

// Everything here is normal, great!

log.js:23 [HMR]  - ../../../../../src/app/public/home/home.component.ts
