The current version of Angular is Release Candidate 1. This version changed the way how the framework is distributed – it comes as a set of scoped npm packages now. Any imports of the Angular classes will be done from @angular instead of angular2, for example: import {bootstrap} from '@angular/platform-browser-dynamic'; import {Component} from '@angular/core'; The content of package.json, index.html, and the configuration of the SystemJS loader has to be changed accordingly. This post is an extract of our book Angular 2 Development with Typescript, and it’ll show you how to get started with a new Angular 2 RC.1 project. You can find the source code of the initial angular-seed project at https://github.com/Farata/angular2typescript/tree/master/chapter2/angular-seed. To start a new project managed by npm, create a new directory (e.g., angular-seed) and open it in the co... (more)

Oracle Starts Catering to the JavaScript Community with JET By @YFain | @CloudExpo #Cloud

During the last several years Oracle was working on their cloud solution, and several internal teams were creating JavaScript-based Web interfaces for the cloud. At some point Oracle decided to standardize on the set of JavaScript libraries used internally, and they also developed a set of reusable Web UI components both simple (e.g., buttons and forms) as well as complex (data grids, charts, accordion, and fancy gauges). All these components are based on jQuery UI and are responsive, so they can be used on mobile devices. Having a nice set of UI components is great, but is not en... (more)

Angular and TypeScript | @ThingsExpo @YFain #IoT #Angular #TypeScript

Angular, TypeScript, SystemJS, and Browser Cache I was writing a small app in Angular 2 in TypeScript with the on-the-fly transpiling by SystemJS. I needed to implement a router that would switch between the Home and ProductDetail views in a single page app. The root component had two links and was supposed to render either Home or ProductDetail components depending on which link the user clicks. Angular 2 offers a pretty elegant syntax for this: Configure the router to map the component to a URL, and use property binding in the form of [router-link]. Nice and easy, isn't it? Th... (more)

Secrets Of The Masters: Core Java Job Interview Questions

JDJ's Enterprise Editor, Yakov Fain (pictured) writes: If you are planning to hit the job market,  you may need to refresh some of the Java basic terms and techniques to prepare yourself for a technical interview.

These sample questions could also become handy for people who need to interview Java developers (see also ... (more)

JavaScript Ecosystem | @ThingsExpo #IoT #JavaScript #TypeScript #Angular2

Lots of things are happening there. As of today it’s the liveliest software ecosystem. The last time I’ve seen such an interesting gathering was 15 years ago in Java. The Past Fifteen years ago Java developers were looking down on the JavaScript folks. It was assumed that JavaScript was only good for highlighting menus and making an impression that the Web site is current by displaying a running clock on the page. Mobile phones still had buttons with one digits and three letters. There were no App stores. Java was promising “Write once run everywhere”, but now we can see that Ja... (more)
