Angular 2 Choices
Choose a language

JavaScript (ES6 or ES5)

TypeScript

Dart

Anything that transpiles to JS

Setup dev environment

Install Node

Choose Package Manager

Choose Module Loader

Choose Transpiler

Choose Build Tool

ES6 vs TypeScript
https://kangax.github.io/compat-table/es6/

You still have to use a transpiler to  
get ES6 support in IE11

Babel

Traceur

Emerging Stacks
TypeScript
Package Manager: npm

Module Loader: SystemJS

Transpiler: Traceur

Build Tool: Broccoli

ES6
Package Manager: JSPM

Module Loader: SystemJS

Transpiler: Babel

Built Tool: Gulp

Build Search Feature

Data via HTTP

Unit Tests

Integration Tests

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="#item of items; #num = index"></div>

Angular 2 Forms
Forms can be complex

To help, Angular provides

Controls

Validators

Observers

Control
let nameControl = new Control("Abbie");
let name = nameControl.value; // -> Abbie

// now you can query this control for certain values:
nameControl.errors // -> StringMap<string, any> of errors
nameControl.dirty // -> false
nameControl.valid // -> true
<input type="text" ngControl="name">

Control Group
let vehicleInfo = new ControlGroup({
make: new Control('VW'),
model: new Control('Deluxe Samba'),
year: new Control('1966')
});
vehicleInfo.value; // -> {
// make: "VW",
// model: "Deluxe Samba",
// year: "1966"
// }

FORM_DIRECTIVES
import {Component} from 'angular2/core';
import {FORM_DIRECTIVES} from 'angular2/common';

@Component({
selector: 'vehicle-form',
directives: [FORM_DIRECTIVES],

ngForm
directives: [FORM_DIRECTIVES],
template: `
<h2>Vehicle Form</h2>
<form #f="ngForm"
(ngSubmit)="onSubmit(f.value)">
<label for="name">Name</label>
<input type="text" id="name"
placeholder="Name" ngControl="name">
<button type="submit">Submit</button>
</form>`

ngSubmit
export class VehicleForm {
onSubmit(form: any): void {
console.log('form value:', form)
}
}

FormBuilder
export class VehicleFormBuilder {
myForm: ControlGroup;
constructor(fb: FormBuilder) {
this.myForm = fb.group({
'name': ['Hefe']
})
}
}

ngFormModel
<form [ngFormModel]="myForm"
(ngSubmit)="onSubmit(myForm.value)">
<input type="text" id="name" placeholder="Name"
[ngFormControl]="myForm.controls['name']">

Validation
constructor(fb: FormBuilder) {
this.myForm = fb.group({
'name': ['', Validators.required]
})
}

Validation
<div class="form-group"
[class.has-error]="!myForm.find('name').valid
&& myForm.find('name').touched">

Validation
<input type="text" id="name" placeholder="Name"
[ngFormControl]="myForm.controls['name']"
#name="ngForm">
<span *ngIf="!name.control.valid" class="help-block">
Name is invalid
</span>
<span *ngIf="name.control.hasError('required')"
class="help-block">Name is required</span>

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
