          },

به عنوان مثال قصد داریم ماژول LazyModule را به صورت پویا بارگذاری کرده و LazyComponent موجود در این ماژول را به صورت پویا در برگه‌ی جدیدی نمایش دهیم. برای این منظور کدهای فایل AppComponent.ts را به شکل زیر تغییر خواهیم داد:

import { Component } from '@angular/core';
import { IdModel } from './core/models/id-model';
import { LazyComponent } from './lazy/lazy.component';
import { OpenNewTabModel } from './core/models/open-new-tab-model';
import { TabService } from './core/services/tab.service';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
  title = 'MaterialAngularTabLayout';
  constructor(private tabService: TabService) {}
  loadLazyComponent() {
    this.tabService.open(<OpenNewTabModel>{
      label: 'Loaded Lazy Component',
      iconName: 'thumb_up',
      componentType: LazyComponent,
      modulePath: 'src/app/lazy/lazy.module#LazyModule',
      data: [{ provide: IdModel, useValue: <IdModel>{ id: 1 } }]
    });
  }
}

در تکه کد بالا با تزریق TabService به سازنده‌ی آن، قصد گشودن برگه‌ی جدیدی را توسط متد open آن، داریم. در بدنه‌ی متد loadLazyComponent یک شیء با قرارداد OpenNewTabModel ایجاد شده و به عنوان آرگومان به متد open ارسال شده است. توجه داشته باشید که modulePath اینجا نیز به مانند خصوصیت loadChildren مرتبط با اشیاء مسیریابی، باید مقدار دهی شود. همچنین قصد داشتیم اطلاعاتی را نیز به کامپوننت مورد نظر ارسال کنیم؛ همانند مکانیزم مسیریابی که با پارامترها این چنین کارهایی صورت می‌پذیرد. در اینجا از یک کلاس به شکل زیر استفاده شده‌است:

export class IdModel {
  constructor(public id: number) {}
}

در این صورت پیاده سازی LazyComponent نیز به شکل زیر خواهد بود:

import { Component, OnInit } from '@angular/core';

import { IdModel } from './../core/models/id-model';

@Component({
  selector: 'app-lazy',
  templateUrl: './lazy.component.html',
  styleUrls: ['./lazy.component.scss']
})
export class LazyComponent implements OnInit {
  constructor(private model: IdModel) {}

  ngOnInit() {
    console.log(this.model);
  }
}

البته فراموش نکنید کامپوننتی را که نیاز است به صورت پویا بارگذاری شود، در قسمت entryComponents مرتبط با NgModule متناظر به شکل نیز معرفی کنید:

import { CommonModule } from '@angular/common';
import { LazyComponent } from './lazy.component';
import { NgModule } from '@angular/core';

@NgModule({
  imports: [CommonModule],
  declarations: [LazyComponent],
  entryComponents: [LazyComponent]
})
export class LazyModule {}

با خروجی زیر:

و chunk تولید شده برای ماژول مورد نظر:

در صورتیکه در حالت production پروژه را بیلد کنید، هش مرتبط برای chunk تولید شده نیز ایجاد خواهد شد.

{
    public string Name { get; set; }
    public int Calories { get; set; }

    orderby i.Name
    select i.Name;
