#DevoxxUK Get Started with Angular Angular QuickStart https://angular.io/docs/ts/latest/quickstart.html Angular Seed
https://github.com/mgechev/angular-seed Angular Seed Advanced https://github.com/NathanWalker/angular-seed-advanced

#DevoxxUK Angular Demo! Start with angular-cli Build Search Feature Data
via HTTP Form Validation CSS Frameworks

#DevoxxUK 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>

#DevoxxUK 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>

#DevoxxUK The asterisk (*) eﬀect   <p *ngIf="condition"> Our heroes are true! </p>  <template [ngIf]="condition"> <p> Our heroes are true! </p> </template>

#DevoxxUK Angular Forms Template-Driven import { FormsModule } from '@angular/forms';
Reactive Forms import { ReactiveFormsModule } from '@angular/forms';

#DevoxxUK 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>

#DevoxxUK 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>

#DevoxxUK Data Architectures MVW / Two-way binding Flux Observables

#DevoxxUK 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

Testing Applications

#DevoxxUK Quality “A person who knows how to ﬁx motorcycles—with
Quality—is less likely to run short of friends than one who doesn't. And they aren't going to see him as some kind of object either. Quality destroys objectivity every time.” — Zen and the Art of Motorcycle Maintenance

#DevoxxUK Software Testing With motorcycles, you drive to test them.
With software, you can test it without driving it. Or rather, you can automate the driving. If you don’t automate tests, you’re still testing!

#DevoxxUK Types of Tests Unit Tests End-to-End Tests
