基于Angular中的条件加载ngModule及其组件 [英] Load ngModule and its components based on conditional in Angular

问题描述

我是angular的新手，我想知道是否有可能基于app.module的条件来加载和模块化我制作的组件及其组件，或者这是在哪里做的最好的地方.

I'm new in angular and I was wondering if it's possible to load and module and its components I made based on a conditional on the app.module or where would it be the best place to do this.

基本上我想做类似的事情:

Basically I want to do something like:

if(user.deparment === 'coms') {
  //Use the communications.module and its components
}

我附上了一些图片，以便大家看到应用程序的结构.如有必要，我可以添加代码而不是图片.

I have attached some picture so you guys can see the structure of the app. if necessary I can add the code instead of a picture.

推荐答案

您可以执行简单的三元检查以有条件地导入模块.像这样:

You can do a simple ternary check to conditionally import a module. Like this:

import { NgModule, Optional } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { AppComponent } from './app.component';

@NgModule({}) class MyModule {}

// toggle and watch the console
const production = true;

@NgModule({
  imports:      [ BrowserModule, production ? MyModule : []],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule {
  constructor(@Optional() module: MyModule) {
    console.log(module);
  }
}
