Angular 更改组件声明位置

Question

这可能是个愚蠢的问题，但事实就是如此：

在我的 angular 项目中，我想将我的组件声明从 angular.module.ts 更改为 modules/modules.modules.ts.

为了使我的 src/app 结构看起来像：

src/
   app/
   .  modules/
   .  .  about/...
   .  .  banner/...
   .  .  contact/...
   .  .  portfolio/...
   .  .  services/...
   .  .  testimonial/...
   .  .  modules.module.ts
   .  app-routing.module.ts
   .  app.component.html
   .  app.component.scss
   .  app.component.spec.ts
   .  app.component.ts
   .  app.module.ts

在 Resume 中想要将我所有的组件声明移动到 modules/modules。module.ts

这是我迄今为止最好的尝试：

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

// Modules Components
import { BannerComponent } from './banner/banner.component';
import { ServicesComponent } from './services/services.component';
import { PortfolioComponent } from './portfolio/portfolio.component';
import { TestimonialComponent } from './testimonial/testimonial.component';
import { AboutComponent } from './about/about.component';
import { ContactComponent } from './contact/contact.component';

@NgModule({
  imports: [CommonModule],
  declarations: [
    AboutComponent,
    BannerComponent,
    ContactComponent,
    PortfolioComponent,
    ServicesComponent,
    TestimonialComponent,
  ],
  exports: [
    AboutComponent,
    BannerComponent,
    ContactComponent,
    PortfolioComponent,
    ServicesComponent,
    TestimonialComponent,
  ],
})
export class ModulesModule {}

app.module.ts:

// Angular CLI
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

// App Component
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

// Pages Components
import { HomePageComponent } from './pages/home-page/home-page.component';
import { AboutPageComponent } from './pages/about-page/about-page.component';
import { ServicesPageComponent } from './pages/services-page/services-page.component';
import { PortfolioPageComponent } from './pages/portfolio-page/portfolio-page.component';
import { PortfolioSinglePageComponent } from './pages/portfolio-single-page/portfolio-single-page.component';
import { ContactPageComponent } from './pages/contact-page/contact-page.component';

// Modules Components
//import { BannerComponent } from './modules/banner/banner.component';
//import { ServicesComponent } from './modules/services/services.component';
//import { PortfolioComponent } from './modules/portfolio/portfolio.component';
//import { TestimonialComponent } from './modules/testimonial/testimonial.component';
//import { AboutComponent } from './modules/about/about.component';
//import { ContactComponent } from './modules/contact/contact.component';
import { ModulesModule } from './modules/modules.module';

// Angular Material
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MaterialModule } from './material/material.module';

// Third Party
import { OwlModule } from 'ngx-owl-carousel';
import { NgxSpinnerModule } from 'ngx-spinner';

// PWA
import { ServiceWorkerModule } from '@angular/service-worker';

// Environment
import { environment } from '../environments/environment';

// Firebase
import { AngularFireModule } from '@angular/fire';
import { AngularFireDatabaseModule } from '@angular/fire/database';

@NgModule({
  declarations: [
    AppComponent,
    HomePageComponent,
    AboutPageComponent,
    ServicesPageComponent,
    ContactPageComponent,
    PortfolioPageComponent,
    PortfolioSinglePageComponent,
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    ModulesModule, // here
    BrowserAnimationsModule,
    MaterialModule,
    OwlModule,
    NgxSpinnerModule,
    ServiceWorkerModule.register('ngsw-worker.js', {
      enabled: true, //environment.production,
    }),
    AngularFireModule.initializeApp(environment.firebaseConfig),
    AngularFireDatabaseModule,
  ],
  providers: [],
  bootstrap: [AppComponent],
})
export class AppModule {}

请注意，我只是更改名称以简化问题。当声明在应用程序中失效时，它完全正常工作。module.ts

Answer 1

您需要 export ModulesModule 中的每个组件。此策略类似于 Sharing modules 中描述的内容。此外，您收到的错误似乎是围绕 owl 传送带、angular 路由器以及可能的其他模块的未知元素错误。尝试创建一个 SharedModule imports/exports 这些第三方模块以及任何共享组件，并将其导入到使用它们的其他模块中：

已分享：

@NgModule({
 imports:      [CommonModule],
 declarations: [],
 exports:      [CommonModule, OwlModule, RouterModule]
})
export class SharedModule { }

模块：

@NgModule({
  imports: [SharedModule],
  declarations: [
    Component1,
    Component2,
  ],
  exports: [
    Component1,
    Component2,
  ],
})
export class ModulesModule { }

希望对您有所帮助！

Answer 2

根据您的错误，您需要：

在您的 ModulesModule 中导入 RouterModule
在您的 ModulesModule 中导入 OwlModule
