• app.component.ts

Javascript

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

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    providers: [],
})
export class AppComponent {
    constructor() { }
    ngOnInit() { }
}

Javascript

import { NgModule } from '@angular/core';
import { BrowserModule }
    from '@angular/platform-browser';
import { RouterModule } from '@angular/router';
import { BrowserAnimationsModule }
    from '@angular/platform-browser/animations';
import { FileUploadModule } from 'primeng/fileupload';

import { HttpClientModule } from '@angular/common/http';

@NgModule({
    imports: [
        BrowserModule,
        BrowserAnimationsModule,
        HttpClientModule,
        FileUploadModule,
        RouterModule.forRoot([{ path: '',
                                component: AppComponent }]),
