你如何从npm定义一个自定义的角度模块？
我创建了一个npm模块并成功发布。 现在我试图弄清楚如何将它包含到我的应用程序中。 我正在使用webpack进行编译，似乎无法做到。 这是一个有角度的通用设置。
Angular通用的回购是：
https://github.com/angular/universal-starter/tree/master/custom-webpack
这里是模块的git回购： https ： //github.com/ChrisTarasovs/angular2-ui-kit
在我的app.module.ts项目中，我做到了
import { BoxModule } from 'ng-universal-ui-kit';
@NgModule({
imports: [BoxModule ],
declarations: [ AppComponent, HomeView ],
exports: [ AppComponent ]
})
export class AppModule {}
我得到的错误是：
Error: Cannot find module 'ng-universal-ui-kit'

import { TransferState } from '../modules/transfer-state/transfer-state';
import { REQUEST } from '@nguniversal/express-engine/tokens';
@Component({
selector: 'demo-app',
template: `
<Box>Lovely Wuhuu</Box>
<h1>Universal Demo using Angular</h1>
<a routerLink="/">Home</a>
<a routerLink="/lazy">Lazy</a>
<router-outlet></router-outlet>
`,
styles: [
`h1 {
color: green;
}`
]
})
export class AppComponent implements OnInit {
constructor(private cache: TransferState) { }
ngOnInit() {
// This is an example
this.cache.set('message', 'Hello World');
}
}
你不应该在AppModule声明它。 您发布到npm的模块应该在BoxModule的exports中列出Box 。
然后，当您导入BoxModule时，您可以使用此组件。
虽然这几乎是错误信息所指出的; 所以不确定是否/为什么你还没有尝试过。
