angular6-hmr
提供angular6以上HMR(熱更新)功能
步驟
1、進入angular項目父級目錄內
git clone https://github.com/staven630/...
angular6-hmr目錄與angular項目(例如:my-app)是同級關係
2、執行gulp hmr --dir angular目錄名
如:
gulp hmr --dir my-app
3、進入angular項目目錄,安裝@angularclass/hmr
npm install --save-dev @angularclass/hmr --registry https://registry.npm.taobao.org
4、這樣angular項目的HMR就配置完成了,執行
npm run hmr
注:保持項目名(package.json中的name)與項目目錄名一致
以下爲手動配置步驟
Angular6添加HMR
environments目錄
environments.ts和environment.prod.ts增加hmr: false
export const environment = {
hmr: false
};
複製environment新增environment.hmr.ts修改hmr:true
export const environment = {
hmr: true
};
.angular.json文件
build的configurations中添加
"hmr": {
"fileReplacements": [
{
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.hmr.ts"
}
]
}
serve的configurations中添加
"hmr": {
"hmr": true,
"browserTarget": "my-app:build:hmr"
}
tsconfig.app.json的compilerOptions的types中添加
"types": ["node"]
package.json的scripts中添加
"hmr": "ng serve --configuration hmr --open"
安裝依賴
npm install --save-dev @angularclass/hmr
src目錄下創建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();
});
};
修改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));
}
Angular5添加HMR
environments目錄
environments.ts和environment.prod.ts增加hmr: false
export const environment = {
hmr: false
};
複製environment新增environment.hmr.ts修改hmr:true
export const environment = {
hmr: true
};
.angular-cli.json的environments中添加
"hmr": "environments/environment.hmr.ts"
在package.json的scripts中增加
"hmr": "ng serve --hmr -e=hmr --open"
安裝依賴
npm install --save-dev @angularclass/hmr

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

module.hot.accept();

const appRef: ApplicationRef = ngModule.injector.get(ApplicationRef);
const elements = appRef.components.map(c => c.location.nativeElement);
const makeVisible = createNewHosts(elements);
ngModule.destroy();
makeVisible();
});
};

hmrBootstrap(module, bootstrap);

console.log('Are you using the --hmr flag for ng serve?');
}
} else {
bootstrap().catch(err => console.log(err));
