Easiest ways to get started
Angular QuickStart
https://github.com/angular/quickstart
Angular Seed
https://github.com/mgechev/angular-seed
Angular CLI
https://github.com/angular/angular-cli
Angular Demo!
Start with angular-cli
Build Search Feature
Data via HTTP
Form Validation
CSS Frameworks
Security
Built-in Components
<div *ngIf="str == 'yes'"></div> <div [ngSwitch]="myVar"> <div *ngSwitchWhen="'A'"></div> </div> <div [ngStyle]="{color: colorinput.value}"></div> <div [ngClass]="{bordered: true}"></div> <div *ngFor="let item of items; let num = index"></div>
The asterisk (*) effect
https://angular.io/docs/ts/latest/guide/structural-directives.html#!#asteris
<div *ngIf="hero">{{hero}}</div> <div *ngFor="let hero of heroes">{{hero}}</div>
The asterisk (*) effect
<!-- Examples (A) and (B) are the same --> <!-- (A) *ngIf paragraph --> <p *ngIf="condition"> Our heroes are true! </p>
<!-- (B) [ngIf] with template --> <template [ngIf]="condition"> <p> Our heroes are true! </p> </template>
Angular Forms
Template-Driven
import { FormsModule } from '@angular/forms';
Reactive Forms
import { ReactiveFormsModule } from '@angular/forms';
Template-Driven Validation
<label for="name">Name</label> <input type="text" class="form-control" id="name" required [(ngModel)]="model.name" name="name" #name="ngModel" > <div [hidden]="name.valid || name.pristine" class="alert alert-danger"> Name is required </div>
Reactive Forms Validation
<form [formGroup]="heroForm" *ngIf="active" (ngSubmit)="onSubmit()"> <label for="name">Name</label> <input type="text" id="name" class="form-control" formControlName="name" required > <div *ngIf="formErrors.name" class="alert alert-danger"> {{ formErrors.name }} </div> </form>
Data Architectures
MVW / Two-way binding
Flux
Observables
Observables and RxJS
Promises emit a single value whereas streams emit many values
Imperative code “pulls” data whereas reactive streams “push” data
RxJS is functional
Streams are composable
