Angular 7 将导入的模块传递给功能模块 [英] Angular 7 Pass Imported Module to Feature Module

问题描述

我在 Angular 7 应用程序中有一个功能模块的层次结构.它的结构如下:

I have a hierarchy of feature modules in an Angular 7 app. It is structured as follows:

• 应用
  • admin(此处导入的 UI 模块)
    • 功能 1
    • 功能2

    在管理模块中，我导入了一个 UI 框架模块.我的问题是，如果我的模块是向上"导入的，这是否也意味着 feature1 模块中的组件可以访问 UI 模块，还是我需要在每个功能模块中导入 UI 模块?我对孩子"有根本的误解吗?模块?

    In the admin module, I have imported a UI framework module. My question is, if my modules are imported "upward", should that also mean that the components in feature1 module have access to the UI module, or do I need to import the UI module in each feature module? Do I have fundamental misunderstanding of "child" modules?

    应用模块

        import { BrowserModule } from '@angular/platform-browser';
        import { NgModule } from '@angular/core';
        
        import { AppComponent } from './app.component';
        import { AppRoutingModule } from './app-routing.module';
        import { AdminModule } from './modules/admin/admin.module';
        import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
    
        @NgModule({
          declarations: [
            AppComponent
          ],
          imports: [
            BrowserModule,
            BrowserAnimationsModule  ,
            AdminModule,
            AppRoutingModule
          ],
          providers: [],
          bootstrap: [AppComponent]
        })
        export class AppModule { }
    

    管理模块

        import { NgModule } from '@angular/core';
        import { CommonModule } from '@angular/common';
        import { AdminRoutingModule } from './admin-routing.module';
        import { UIFrameworkModule} from '@ui-framework/angular';
        
        import { Feature1Module} from './modules/feature1/feature1.module';
        import { Feature2Module} from './modules/feature2/feature2.module';
        
        @NgModule({
          imports: [
            CommonModule,
            Feature1Module,
            Feature2Module,
            AdminRoutingModule,
            UIFrameWorkModule
          ]
        })
        export class AdminModule {}
    

    feature1.module

    feature1.module

        import { NgModule } from '@angular/core';
        import { CommonModule } from '@angular/common';
        import { Feature1RoutingModule} from './feature1-routing.module';
        
        @NgModule({
          imports: [
            CommonModule,
            Feature1RoutingModule
          ]
        })
        export class Feature1Module {}

    你可以有多个模块 - 但问题是如何将一个模块导入到单个导入数组中的所有模块 - 模块的主要行为来了分离

    You can have as many modules - but the question is how to import a module to all the module in a single import array - there comes the main act of module separation

    创建一个新模块作为共享模块该模块不包含任何组件或指令，如果它没有任何问题 - 该模块应该是导入所有公共模块的模块

    Create a new module as shared module this module doesn't hold any components or directives if it has any not an issue - this module should be the module that imports all your common module

    在您的情况下 UIFrameWorkModule 这是您想要在功能和管理模块中访问的公共模块，如果是这种情况，请创建一个共享模块并导入此模块并导出该共享模块，例如代码如下

    In your case UIFrameWorkModule this is the common module that you want to access both in feature and admin module if that is the case create a shared module and import this module and export that shared module like the code below

    import { NgModule } from '@angular/core';
    import { CommonModule } from '@angular/common';
    import { UIFrameworkModule } from '@ui-framework/angular';
    
    @NgModule({
      imports: [
        CommonModule,
        UIFrameworkModule 
      ],
      exports:[UIFrameworkModule]
    })
    export class SharedModule {}
    

    现在这个共享模块保存了 UIFrameworkModule 并导出相同的模块 - 你必须在任何你想要的地方导入这个共享模块，这将把 UIFrameworkModule 带到导入模块

    Now this shared module holds the UIFrameworkModule and export the same module too - You have to just import this shared module where ever you want that will bring the UIFrameworkModule to the imported module

    管理模块

    import { NgModule } from '@angular/core';
    import { CommonModule } from '@angular/common';
    import { AdminRoutingModule } from './admin-routing.module';
    import { UIFrameworkModule} from '@ui-framework/angular';
    
    import { Feature1Module} from './modules/feature1/feature1.module';
    import { Feature2Module} from './modules/feature2/feature2.module';
    
    @NgModule({
      imports: [
        CommonModule,
        Feature1Module,
        Feature2Module,
        AdminRoutingModule,
        SharedModule 
      ]
    })
    export class AdminModule {}
    

    功能模块

    import { NgModule } from '@angular/core';
    import { CommonModule } from '@angular/common';
    import { Feature1RoutingModule} from './feature1-routing.module';
    
    @NgModule({
      imports: [
        CommonModule,
        Feature1RoutingModule,
        SharedModule 
      ]
    })
    export class Feature1Module {}
    

    我刚刚在两个模块中导入了共享模块，就像你可以将所有通用模块移动到共享模块一样 - 希望这会有所帮助 - 感谢快乐编码！！

    I have just imported the shared module in both the modules like wise you can move all your common module to the shared modules - hope this helps - Thanks happy coding !!
