None
ES6 IN A NUTSHELL • New features: classes, modules, promises,
arrows, generators, and more. • Additive only, doesn’t remove existing features. • Most features can be transpiled to current ES5.
TYPESCRIPT IN A NUTSHELL • Transpiler to compile down to
ES6/5/3. • Adds strict typings to variables. • Only extends JavaScript syntax.
ES6/TYPESCRIPT PRIMER const stocks = ['AAPL', 'GOOG', 'FB', 'AMZN']; ES6
const keyword
ES6/TYPESCRIPT PRIMER let name = 'Jeremy'; let template = `
<h1>Template by ${name}</h1> <p>I can write markup without escaping and write on multiple lines!</p> `; ES6 inline multiline template strings
ES6/TYPESCRIPT PRIMER let stocks = ['aapl', 'goog', 'fb', 'amzn']; class
Dashboard { constructor() { stocks.forEach(stock => { this.add(stock.toUpperCase()); }); } add(stock) { this.stocks.push(stock); } } ES6 arrow functions
ES6/TYPESCRIPT PRIMER class Dashboard { constructor(service) { this.symbols = service.get();
} reset() { this.symbols = []; } } ES6 classes
ES6/TYPESCRIPT PRIMER import {service} from './service'; export class Dashboard {
constructor() { this.symbols = service.get(); } } ES6 modules
ES6/TYPESCRIPT PRIMER @Component({ selector: 'app' }) export class App {
} ES7 decorators
ES6/TYPESCRIPT PRIMER interface StockInterface { symbol: string, lastTradePriceOnly: number, change:
number, changeInPercent: number } let stocks: Array<StockInterface> = []; Typescript interfaces and type declarations
CODE TIME https://github.com/gnomeontherun/ angular2-uxdsummit
THE BASE Uses a node module lite-server as local server.
Files are transpiled with TypeScript.
Build & Server
THE APP COMPONENT Creating the app component, and bootstrapping it
Build & Server App Component index.html
THE STOCK SERVICE Creating a reusable service to manage stocks
collection
Build & Server App Component index.html Stock Service
THE SUMMARY COMPONENT Using directives, types, and bindings
Build & Server App Component index.html Stock Service Summary Component
THE DASHBOARD COMPONENT Loading data, using services, and importing components.
Build & Server App Component index.html Stock Service Summary Component
Dashboard Component
LET’S REVIEW Basic scaffolding to build and serve the app
App component is bootstraped to start rendering Services are used to load and manage data Simple components are nested to create larger features Pipes and directives manipulate rendered data
