angular nrwl/nx项目 hmr 开发热更新设置

如题：angular nrwl/nx项目 hmr 热更新设置

nx介绍：https://nx.dev/getting-started/what-is-nx

设置：

1、angular.json设置：

// 对应 app 的build与serve下的configurations加 hmr, 同时设置environments目录相应ts
"build": {
"configurations": {
"hmr": {
  "fileReplacements": [
    {
      "replace": "apps/system-admin/src/environments/environment.ts",
      "with": "apps/system-admin/src/environments/environment.hmr.ts"
    }
  ]
}
},
}
"serve": {
"configurations": {
  "production": {
    "browserTarget": "midback-admin:build:production"
  },
  "hmr": {
    "hmr": true,
    "browserTarget": "midback-admin:build:hmr"
  }
}
}

app相应设置，先上个目录结构，以下标红箭头是需要配置的文件：

// environment 目录3个文件

//environment.hmr.ts
export const environment = {
  production: false,
  hmr: true,
};

//environment.prod.ts
export const environment = {
  production: true,
  hmr: false,
};

//environment.ts
export const environment = {
  production: false,
  hmr: false,
};

hmr.ts

import { NgModuleRef, ApplicationRef } from '@angular/core';
import { createNewHosts } from '@angularclass/hmr';

export const hmrBootstrap = (
  module: any,
  bootstrap: () => Promise<NgModuleRef<any>>,
) => {
  let ngModule: NgModuleRef<any>;
  module.hot.accept();
  bootstrap().then(mod => (ngModule = mod));
  module.hot.dispose(() => {
    const appRef: ApplicationRef = ngModule.injector.get(ApplicationRef);
    const elements = appRef.components.map(c => c.location.nativeElement);
    const makeVisible = createNewHosts(elements);
    ngModule.destroy();
    makeVisible();
  });
};

main.ts

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app/app.module';
import { environment } from './environments/environment';

import { hmrBootstrap } from './hmr';

if (environment.production) {
  enableProdMode();
}

const bootstrap = () => platformBrowserDynamic().bootstrapModule(AppModule);

if (environment.hmr) {
  if (module['hot']) {
    hmrBootstrap(module, bootstrap);
  } else {
    console.error('HMR is not enabled for webpack-dev-server!');
    console.log('Are you using the --hmr flag for ng serve?');
  }
} else {
  bootstrap().catch(err => console.log(err));
}

启动程序：yarn ng serve --configuration hmr --project my-app

如果报错：main.ts error TS2304: Cannot find name 'module'. 那就在 tsconfig.app.json 加配置："types": ["node"]

{
  "extends": "../../tsconfig.json",
  "compilerOptions": {
    "outDir": "../../dist/out-tsc/apps/vendor-admin",
    "types": ["node"]
  },
  "exclude": [
    "test.ts",
    "**/*.spec.ts"
  ],
  "include": [
    "**/*.ts"
  
    , "../../libs/vendor-admin/views/vendor-admin/src/index.ts"
]
}

重新启动app，这时应该就没有问题了，试一下修改代码，保存，页面就不会刷新了，一下子人都精神了！！！

如有遗漏，后面补充！
