Spring Boot
Automatically configures Spring whenever possible
Provides production-ready features such as metrics, health checks and externalized configuration
Absolutely no code generation and no requirement for XML configuration
Embeds Tomcat, Jetty or Undertow directly
@SpringBootApplication public class DemoApplication {
public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } }
@Entity class Blog {
@Id @GeneratedValue private Long id; private String name;
// getters, setters, toString(), etc }
@RepositoryRestResource interface BlogRepository extends JpaRepository<Blog, Long> { }

Hello World with React
http://codepen.io/gaearon/pen/ZpvBNJ?editors=0100
<div id="root"></div>
<script> ReactDOM.render( <h1>Hello, world!</h1>, document.getElementById('root') ); </script>
Imperative Codeif (count > 99) { if (!hasFire()) { addFire(); } } else { if (hasFire()) { removeFire(); } } if (count === 0) { if (hasBadge()) { removeBadge(); } return; } if (!hasBadge()) { addBadge(); } var countText = count > 99 ? "99+" : count.toString(); getBadge().setText(countText);
Declarative Codeif (count === 0) { return <div className="bell"/>; } else if (count <= 99) { return ( <div className="bell"> <span className="badge">{count}</span> </div> ); } else { return ( <div className="bell onFire"> <span className="badge">99+</span> </div> ); }

Progressive Web Apps
Mobile Hates You!How to fight back:
Implement PRPL
Get a ~$150-200 unlocked Android (e.g. Moto G4)
Use chrome://inspect && chrome://inspect?tracing
Lighthouse
DevTools Network & CPU Throttling
The PRPL Pattern
Push
Render
Pre-cache
Lazy-load
The PRPL Pattern
Push critical resources for the initial URL route
Render initial route
Pre-cache remaining routes
Lazy-load and create remaining routes on demand

Demo: Build a React Clientclass BeerList extends React.Component<{}, any> { constructor(props: any) { super(props);
this.state = { beers: [], isLoading: false }; }
componentDidMount() { this.setState({isLoading: true});
fetch('http://localhost:8080/good-beers') .then(response => response.json()) .then(data => this.setState({beers: data, isLoading: false})); }
render() { const {beers, isLoading} = this.state; … } }
