In this transcript of a talk held at the HH.JS meetup in Hamburg we give our best to explain the major concepts of Angular2 using a real application you can play with: SPQR. It’s a collaborative platform for an audience to ask a speaker questions during a talk, and upvote the best of them. The code is hosted on Plunkr, an online code editor similar to CodePen with support for Angular2, TypeScript and folder structures. Angular2 Basics Let’s start with what Angular 2 is: A framework to build client-side applicationsCode can be written in Typescript, ES6, Dart or JavaScript (without transpiling)Has an expressive template languagePowerful data bindingAvailable as release candidate 4 (07/26/2016) Okay, so another client-side framework for single page applications, but why?

Project Setup For the SPQR app, we use a very simple project structure. The building blocks of an Angular2 app Structuring application logic. Angular 2 User Registration and Login Example & Tutorial | Jason Watmore's Blog. Built with Angular 2.0 Final. After getting a lot of interest in a previous tutorial I posted on how to build a User Registration and Login with Angular 1, and since Angular 2 Final was recently released I thought it was time to post an updated example built with Angular 2 and TypeScript.

The project is available on GitHub at The example uses a fake backend that stores users in HTML5 local storage, to switch to using a real web service simply remove the fake backend providers in the app.module.ts file below the comment "// providers used to create fake backend". Here it is in action: (See on Plunker at Running the Angular 2 User Registration & Login Example Locally Install NodeJS (> v4) and NPM (> v3) from you can check the versions you have installed by running node -v and npm -v from the command line. Angular 2 Project Structure Angular 2 Auth Guard.

Angular 2's Fresh Approach to Style - Justin Schwartzenberger. Angular2-features/user-card.component.html at master · chsakell/angular2-features. Arrow Functions · Rangle.io : Angular 2 Training. ES6 offers some new syntax for dealing with this: "arrow functions". Arrow function also make working with "higher order" functions (functions that take functions as parameters) much easier to work with. The new "fat arrow" notation can be used to define anonymous functions in a simpler way. Consider the following example: items.forEach(function(x) { console.log(x); incrementedItems.push(x+1); }); This can be rewritten as an "arrow function" using the following syntax: items.forEach((x) => { console.log(x); incrementedItems.push(x+1); }); Functions that calculate a single expression and return its values can be defined even simpler: incrementedItems = items.map((x) => x+1); The latter is almost equivalent to the following: incrementedItems = items.map(function (x) { return x+1; }); There is one important difference, however: arrow functions do not set a local copy of this, arguments, super, or new.target.

Let's try this code on ES6 Fiddle ( Building Angular 2 Web and Native Apps from a Single Codebase -Telerik Developer Network. So, you need to build a web site. Great! If you’re an Angular developer, you immediately dash to your favorite IDE and start scaffolding out your site. But wait! Maybe you also need to build a mobile app to accompany your beautiful new site. Now what? It’s become clear that Angular 2 is not just a framework that you use to spin up web sites.

In this article, I’d like to share with you lessons that I learned by doing this in the real world while making PocketRave.me with the Angular 2 Advanced Seed. Getting Started with the Angular 2 Advanced Seed To build for multiple platforms at once, you need a secret weapon. The Advanced Seed in action Because the advanced seed is very full featured – including i18n multilingual support, unit testing, analytics, and more – you might choose to strip out all the bits and pieces you don’t need.

However, to make this process easier for you, I have created a very stripped-down version of this Advanced Seed, which you can find here. How does it work? DNX Angular2 Example project extension. Sign in to write a review Sort by: Very good starting point for an Angular 2 application! Couple of things I miss: 1. Setup for unit testing2. .ts files separated from the .js files. The .ts files does not need to be published at all.

Could just add compiled .js files to wwwroot/libraries/app/ or something Like the example of how to use controllers and modeles to communicate between frontend and backend. Thanks a lot! Doesn't work. Doesn't work. This is a really nice starting point, Martijn. Great layout and starting point for an Angular 2 application on Visual Studio. Getting started NativeScript Angular 2 and Ionic Framework 2 | CODEQUS.COM. While there is a big buzz around Angular 2 and the Ionic Framework 2, a new force awakens in the shadow of the cross-platform development world. While this force has not yet reached the maturity level of other frameworks, the potential and the chances for success makes this force a worthy candidate to become one of the strongest frameworks on the cross-platform horizon.

The new force we are talking about is NativeScript, a framework to “Build truly native apps with JavaScript” as their page says. Not another framework, cmon! That was my first impression when my good friend Nic Raboy started to blog about NativeScript. But some weeks ago on the German Developer Week conference I had the chance to sit down with the great Sebastian Witalec from the Telerik team, the creators of NativeScript. He gave me very good insight into what NativeScript is and what it isn’t, so today let’s explore what NativeScript can do for you! What is NativeScript? The great thing about it? How? Run on Android or iOS. Gumroad. Gumroad. Highlights from AngularConnect 2016 | Distinction. After a few years of working on Angular apps, I was really excited to get the opportunity to head to London for AngularConnect 2016, especially as Angular 2 was fully released less than 2 weeks prior.

After checking out the schedule online, I could already see a ton of stuff that I was interested in seeing. There were so many useful talks on the day that I had to cover it all, so have a great time learning all about my time at AngularConnect and I would definitely recommend checking out the slides and videos for each of the talks! Day One Day Two Angular Team Panel Closing Thoughts I've been a huge fan of Angular (often shortened to 'ng') since I was first introduced to it a few years ago. Day One Arrival Upon arrival at the ExCel centre, we were greeted by friendly and helpful staff and after a really quick and simple registration we were handed our lanyards and goodie bags before heading into the refreshments area for a cup of tea. Keynote Some interesting points raised: Break Mobile Apps? Hotjs.

Language Options - An Introduction to Angular2 - Falafel Software Blog. Before you start developing an Angular2 application, there are a few selections that you have to make. One of those choices is the programming language that you want to use with Angular2. While Angular2 is a JavaScript framework at heart, there are nevertheless, a few options to choose from.

In this column, we are going to look at the options and examine the differences in syntax, to help you make that choice. Background The JavaScript language specification standard is called ECMAScript, or ES.ECMAScript is standardized by the ECMA International standards organization and overseen by the TC39 committee. ES5 is the version currently supported by most of the browsers. It is the version that many JavaScript developers are still using, especially those developing with plain JavaScript or jQuery.

Angular2 Language Choices There are many options available for front-end developers today, and the same applies to Angular2 applications. The injected DataService (data.service.js) looks like: <! Dart. Listening to Angular Key Events with Host Listeners. This article is for versions of Angular 2 and later. A common pattern in many web applications is the ability to react to users via key board events or shortcuts. This great for user experience and accessibility. Typically we register window and document events to accomplish this. With Angular we try to avoid touching the DOM directly for certain rendering and performance reasons.

There is a specific API within Angular we can use to listen to global window and document events like the keyup and keydown events. To listen to the window for events we will use the HostListener API. This API allows us to register a special listener for events in the browser and then call methods in our components to react to them. In our example we have a simple counter component that can increment and decrement a value on the view. In our rendered counter component I can increment and decrement the value with the buttons and the keyboard arrow keys. The @HostListener has two parameters. Demo. Offline Compilation in Angular 2.0. In this article I will show how to use the offline compiler in Angular to improve performance. Before a component can be rendered by the browser, Angular has to do a fair amount of processing to figure out what the final html should look like. This process of evaluating binding expressions and parsing templates is called template compilation.

As part of template compilation, html templates are converted to executable JavaScript that the browser will execute to render the application. By default template compilation is done by the browser at runtime, but the idea behind offline compilation is to take this processing offline and do it as a build step instead. Depending on the complexity of our templates, doing the compilation offline, may lead to noticeable performance improvements. It also helps reduce the size of Angular itself since we no longer have to send the template compiler to the browser. Another benefit of offline compilation is what we call “Tree shaking”. Bootstrapping . Benefits. Progressive Web Apps with Angular 2+ At the time of writing, the --mobile flag with Angular CLI, which integrates progressive technologies such as offline support into your application, is temporarily disabled. Among other things, this post goes through how I set up offline support using the sw-precache and sw-toolbox libraries on their own.

Progressive Web Apps (PWA) have been the talk of the town in 2016. In short, they are applications that use modern web capabilities to provide a user experience similar to that of mobile and native apps. Still a relatively new concept, these applications work for every user in every browser but are enhanced in some. An earlier post of mine (see here) revolved around building a Hacker News client from scratch using Angular CLI.

Let’s go through some of the main concepts of progressive applications. XKCD - Installing Although installing an app is usually a fast and simple process, when was the last time you were about to install something but decided not to? Ahead-of-Time compilation Icons. Quickstart/README.md at master · angular/quickstart. Sans titre. TL;DR RxJS is a library that allows us to easily create and manipulate streams of events and data. This makes developing complex but readable asynchronous code much easier. Creating large asynchronous applications is not the easiest thing to do. We have all witnessed the issues callback hell can cause.

Due to this growing concern, people have taken it upon themselves to improve the landscape of the asynchronous JavaScript landscape. We have all heard of promises, generators, and async/await. There is another solution, and it is called RxJS. From their Github README, RxJS is defined as "a set of libraries for composing asynchronous and event-based programs using observable sequences and fluent query operators". This concept of an "observable", or "stream" as I like to call them, can be difficult to grasp at first. To demonstrate how this all works, we are going to build a simple weather app. Setting Things Up Load this file in your favorite browser, and open up your developer console. SPA Using Angular 2, ASP.NET Core 1.1 and Entity Framework Core (Part 1) - CodeProject. Introduction This is first part of this series. In this series we will create a SPA application using Angular 2, Asp.Net Core 1.1 and Entity Framework Core.

Here we use Angular 2 as UI for the application, using Asp.Net Core MVC we will perform server side tasks and using Entity Framework Core we perform all the database level operations. In this series we create an Employee Management system project. In this management system we provide features to see the list of all employee, edit the existing employee, delete any particular employee and enter a new employee. Let’s go through the Agenda of this series. Agenda Setup development environment for Angular 2 Understand the structure of application Add Entity Framework in Project Create new pages to see the Employee List and also for Insert, Update and Delete operations.
