将所有模块包装在一起

你还可以轻松地将所有要使用的角度模块包装到一个模块中：

import { NgModule } from '@angular/core';
import { MdButtonModule, MdSnackBarModule, MdSidenavModule } from '@angular/material';
 
@NgModule({
    imports: [
        BrowserAnimationsModule,
        MdButtonModule,
        MdSnackBarModule,
        MdSidenavModule
    ],
    exports: [
        MdButtonModule,
        MdSnackBarModule,
        MdSidenavModule
    ]
})
export class MaterialWrapperModule {}

之后，只需将模块导入应用程序主模块：

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

import { MaterialWrapperModule } from './material-wrapper.module.ts';
import { AppComponent } from './app.component';

@NgModule({
    imports: [
        BrowserAnimationsModule, 
        MaterialWrapperModule,
        CommonModule,
        // This is optional, use it when you would like routing in your app
        // RouterModule.forRoot([
        //     { path: '', component: HomeView, pathMatch: 'full'}
        // ])
    ],
    declarations: [ AppComponent],
    bootstrap: [ AppComponent ]
})
export class AppModule {}
