Lazy-loading

Criando um método para chamar módulos por Lazy Load (Carga sob demanda - Acesso)

/* Dentro do Arquivo routing-module */ import { RouterModule, Routes } from '@angular/router';

const routes: Routes = [

  { path: , component: MainComponent },
  { path: 'v/:id', component: VComponent },
  { path: 'proceedings', loadChildren: () => import('../120_proceddings/proceddings.module').then(m => m.ProceddingsModule)}, 
];

/* Arquivo de módulo destino */

const routes: Routes = [
 { path: , component: MainJournalComponent, children: 
   [
       { path: , component: ProceedingWelcomeComponent },
       { path: 'view/:id', component: ProceddingsViewComponent },
   ]
 } ];

Componentes de outros módulos

No arquivo module.ts

 schemas: [CUSTOM_ELEMENTS_SCHEMA],
 imports: [
   CommonModule,
   ProceddingsRoutingModule,
   ThemeModule
 ]

No arquivo componente

<app-theme-navbar></app-theme-navbar>
<router-outlet></router-outlet>
<app-theme-footer></app-theme-footer>

Componentes

Novo componente

ng g c [/modules/brapci/headers/head]

Route - Routas

ng generate module app-routing --flat --module=app

Rotas com ID

constructor(private ActivatedRoute: ActivatedRoute) {}

ngOnInit() {
  this.ActivatedRoute.params.subscribe(
    res=>console.log(res.id,res.name)
  )
  /*********** GET *********/
  this.ActivatedRoute.queryParams.subscribe(
    res=>console.log(res.id,res.name)
  )
}

Rotas TS

constructor(private Router: Router) {}

Redireciona pagina dentro da programação

this.router.navigate(['home']);
this.router.navigate(['/'])

Com reload da Página

this.router.navigateByUrl('/home');

Rotas Ativas

routerLinkActive
[a routerLink="['/home',1]" [routerLinkActive]="['class_active']" [routerLinkActiveOptions]="{exact: true}">Home 1[a]

routerLink

[a routerLink="['/home',1]">Home 1[a]

Nova Inteface

ng g interface /modules/interface/vocabulary

Data Binding

Interpolation (sem espaços)

{ { title } } (HTML)
public title: string="Título" (TS)

Property Binding

<button [disabled]="disableButton">Botão</button> (HTML)
<img [src]="imageCapaURL"> (HTML)
<img src="Predefinição:ImageCapaURL"> (HTML)

Event Binding

<button (click)="calc()">Calcular</button> (HTML)
<button (click)="calc($event)">Calcular</button> (HTML)
public calc(valor: MouseEvent) { (TS)
  console.log(valor) }

Two-way binding

<input ngModel="nome"> (HTML)
Predefinição:Nome (HTML)
public nome="Nome" (TS)

LocalStorage

ng generate service service/local-storage

Salvando dados no navegador

localStorage.setItem('name', 'Gabriel');

let name = localStorage.getItem('name'); 
alert(`Hello, ${ name }!`); //Hello, Gabriel!

localStorage.removeItem('name');

localStorage.clear();

local-storage.service.ts

import { Injectable } from '@angular/core';

@Injectable({
  providedIn: 'root',
})
export class LocalStorageService {
 private storage: Storage;
 constructor() {
   this.storage = window.localStorage;
 }

 set(key: string, value: any): boolean {
   if (this.storage) {
     this.storage.setItem(key, JSON.stringify(value));
     return true;
   }
   return false;
 } 

 get(key: string): any {
   if (this.storage) {
     return JSON.parse(<any>this.storage.getItem(key));
   }
   return null;
 }

 remove(key: string): boolean {
   if (this.storage) {
     this.storage.removeItem(key);
     return true;
   }
   return false;
 }

 clear(): boolean {
   if (this.storage) {
     this.storage.clear();
     return true;
   }
   return false;
 }
}

For while conditional

[li *ngFor="let item of collection(sources,'JA');let i = index">
               [a class="link" [routerLink]="['/sources/view/' + i]" routerLinkActive="router-link-active">

               [span *ngIf="item.jnl_collection=='JA'">(Revista)
               [/a>
       [/li>

No componente

 collection(journal: any[],type: string=): any {
   return journal.filter(p => p.jnl_collection === type);
 }

Cookie

npm install ngx-cookie-service

No módulo de serviço

import { CookieService } from 'ngx-cookie-service';

public ngOnInit(): void
{
  /******************************************************************** */
  public setLibrary(id: string) {
    this.CookieService.set('library', id);
  }

  public getLibrary() {
    if (this.CookieService.check('library')) {
      return this.CookieService.get('library');
    } else {
      return 0
    }
  }
 }

Tradução Angular

npm i @ngx-translate/core @ngx-translate/http-loader

Após adicionar esse pacote, é necessário importa-lo para nossa aplicação, colocando-o no app.module.ts, como demonstra o exemplo abaixo:

@NgModule({
 declarations: [
   AppComponent
 ],
 imports: [
   BrowserModule,
   HttpClientModule,
   TranslateModule.forRoot({
     loader: {
       provide: TranslateLoader,
       useFactory: HttpLoaderFactory,
       deps: [HttpClient]
     }
   })
 ],
 providers: [],
 bootstrap: [AppComponent]
})

export class AppModule { }

export function HttpLoaderFactory(http: HttpClient) {
 return new TranslateHttpLoader(http);
}

Bootstrap Angular

ng add @ng-bootstrap/ng-bootstrap
npm install bootstrap bootstrap-icons

/* Editar o arquivoi angular.json */
"styles": [
  "node_modules/bootstrap/scss/bootstrap.scss",
  "node_modules/bootstrap-icons/font/bootstrap-icons.css",
  "src/styles.scss"
],
"scripts": [
  "node_modules/bootstrap/dist/js/bootstrap.bundle.min.js"
]

npm install @ng-bootstrap/ng-bootstrap

Variáveis

public title:string = "Brapci";
public valor:number = 1;
public valido:boolean = true;
public position: { x: number, y: number } = { x: 0, y: 0 };
public date: Data = new Date();

Array

public list: Array<{ nome: string, idade: number}> = [
 { nome: "Rene", idade: 53 },
 { nome: "Viviade", idade: 52 },
];

Insere um tiem em uma array

this.list.push({nome: "Nome", idade: 31 });

Remove um item de uma array

this.list.splice(id)

Array Sample

     let dt: Array<any> | any = {
       di: dataS,
       df: dataF,
       field: this.field_search,
     };
