})(this);
Then run this command in the directory you are running your project in
sudo npm install
Then create a plaintext mkdir app followed by:
touch app.module.ts
touch main.ts
touch homepage.component.ts
To start the server, type npm start

Creating the main app files
We need to create an AppRoutingModule, AppComponent, AppComponent.html, AppModule, and Main.ts files for the app to be able to bootstrap.
Sample file are found below:
// app-routing-module.ts
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { HomepageComponent } from './homepage/homepage.component';
import { DocumentsComponent } from './documents/documents.component';
import { ProposalListComponent } from './proposal/proposal-list.component';
import { ProposalNewComponent } from './proposal/proposal-new.component';
const routes : Routes = [
{ path: '', redirectTo: '/home', pathMatch: 'full' },
{ path: 'home', component: HomepageComponent },
{ path: 'documents', component: DocumentsComponent },
{ path: 'proposals', component: ProposalListComponent },
{ path: 'proposals/new', component: ProposalNewComponent },
]
@NgModule({
imports: [ RouterModule.forRoot(routes) ],
exports: [ RouterModule ]
})
export class AppRoutingModule {}
// app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppRoutingModule } from './app-routing.module';
import { HomepageComponent } from './homepage/homepage.component';
import { AppComponent } from './app.component';
import { DocumentsComponent } from './documents/documents.component';
import { ProposalListComponent } from './proposal/proposal-list.component';
import { ProposalNewComponent } from './proposal/proposal-new.component';
@NgModule({
imports: [
BrowserModule,
AppRoutingModule,
FormsModule
],
declarations: [
AppComponent,
HomepageComponent,
DocumentsComponent,
ProposalListComponent,
ProposalNewComponent
],
bootstrap: [
AppComponent
]
})
export class AppModule {}
// app.component.ts
import { Component } from '@angular/core';
@Component({
moduleId: module.id,
selector: 'app',
templateUrl: 'app.component.html'
})
export class AppComponent {
title: 'Freelance Bootcamp Dashboard';
}
<!-- app.component.html -->
<h1>Navigation</h1>
<a routerLink="/home">Home</a>
<a routerLink="/documents">Docs</a>
<a routerLink="/proposals">Proposals</a>
<a routerLink="/proposals/new">New Proposal</a>
<router-outlet></router-outlet>
// main.ts
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';
const platform = platformBrowserDynamic();
platform.bootstrapModule(AppModule);
