Angular 2 Development With TypeScript


Angular 2 Development with Typescript introduces Angular 2 to developers comfortable using AngularJS v1 or other web frameworks. You'll start by exploring how Angular 2 works in an online auction application. Along the way, you'll learn to use TypeScript to write type-aware classes, interfaces, and generics. This is a practical book that covers real-world development concerns like data and views, user interaction with forms, and communicating with servers, as well as testing and deploying your Angular 2 applications.




Angular 2 Development with TypeScript



Yakov Fain is a New York-based Java Champion and partner at IT consultancy Farata Systems. He leads the Princeton JUG, has authored many articles on software development and several books. Recently he co-authored the book "Angular 2 Development with TypeScript", that will be published by Manning in June of 2016. Yakov often speaks at conferences and teaches Java and Angular 2 classes. He blogs at yakovfain.com.


AngularJS turned the front-end development world upside down when it was released, bringing together a number of new or recent web application development practices into a powerful and easy-to-use framework. With version 2, the Angular team has started from scratch with a completely new system. Many of the ideas behind Angular are still the same, but the API and developer experience are very different.


Best to choose a code Editor for Angular 2 development that understands TypeScript by default (or via a plugin) and is considerate of modern JavaScript development (i.e. Node/npm development). Visual Studio Code, Atom, or WebStorm seem to be the ideal choices today. While you might love another editor, getting started with Angular 2 will likely be easier when using one of these editors.


As for RxJS, take a closer look at it. It's endorsed by the Angular 2 project and plays a major role in application development when dealing with HTTP responses on the client. So, yeah, no real reason to sidestep RxJS or put it off. Just learn it.


If you are building an Angular 2 application for an environment that runs ES5, ES6, and some future ES* code with no issue, you are golden. Otherwise, a polyfill will be needed. The Angular 2 project depends upon core-js to make sure Angular 2 code can run in an environment that does not support ES5, ES6, and ES* perfectly. While not exactly necessary to do Angular 2 development, I believe it is a good idea to understand what core-js is doing at runtime.


For most JavaScript developers, this stuff is commonplace. But, if you are just learning Angular 2 along with the tools that make development possible, the multiple Node processes might come as a surprise. Just keep in mind that your terminal will be running several process that make Angular 2 development possible. You'll need to be aware this fact and often the output from these processes will be mission critical to development.


For the most part, if you think/develop in OOP terms, you should be right at home with Angular 2 development. However, given Angular 2's use of RxJS and things like ngrx/store, you should be aware that functional programming concepts are infringing upon a strict OOP developer mindset. Ease yourself into functional programming because Angular 2 isn't shying away from it. Try it - you might just like it.


Angular is a popular web development platform developed and maintained by Google. Angular uses TypeScript as it's main programming language. The Visual Studio Code editor supports TypeScript IntelliSense and code navigation out of the box, so you can do Angular development without installing any other extension.


React is a library for building user interfaces and it is more minimal than angular. If you'd like to see an example of React working with VS Code, check out the Using React in VS Code tutorial. It will walk you through creating an React application and configuring the launch.json file for the JavaScript debugger.


The roots of Generator-M-Ionic reach back more than two years when my team and I (@gruppjo) at M-Way Solutions decided to move our HTML5 mobile app development stack to Angular and Ionic in early 2014. Since then Generator-M-Ionic has grown into a full-fledged collection of development tools for building large-scale enterprise apps with Cordova, Angular and Ionic.


Built on top of the Yeoman Ecosystem with Gulp, Bower and npm, Generator-M-Ionic offers highly efficient workflows for building apps from start to finish by wiring together a complex technology stack and by providing workflows for all important aspects of professional cross-platform HTML5 app development with Cordova, Angular and Ionic.


Angular is a platform that makes it easy to build applications with the web. Angular combines declarative templates, dependency injection, end to end tooling, and integrated best practices to solve development challenges. Angular empowers developers to build applications that live on the web, mobile, or the desktop


A Code Editor has been the basic primary tool for any kind of programming. It is responsible for boosting a developer's efficiency as well as bringing it down. There are so many code editors available today and for the same reason, it is highly crucial to choose the right tool for right kind of development. I prefer using VS Code for Angular 2 development but each individual can have their own opinion. I have listed some popular code editors with their support for Angular 2 so that a programmer can choose what suits the best and use the tool effectively.


With over a decade of development background, we work with open technologies like Elixir, Phoenix Framework, Ruby on Rails, Ember.js, React.js, React Native for Android, iOS etc. in bringing ideas to life for our clients and partners.


Designing complex dynamic web pages with pure or vanilla JavaScript is time-consuming. Not to mention that, in big projects involving many programmers, the front-end is a challenge to understand and maintain. So, the key idea behind AngularJS was to simplify SPA development by introducing several considerable advantages.


The component-based architecture allows for building UIs with many moving parts and, at the same time, streamlines the development course for engineers. Other main benefits of such a design are as follows.


Maintainability. Components that are easily decoupled from each other can be easily replaced with better implementations. Your engineering team will be more efficient in maintaining and updating the code within the iterative development workflow.


The same applies to Angular itself. Considering that the team has an impressive rhythm with new versions coming in about six months, there must be a simple way to update Angular itself without breaking anything. Ng update @angular/core will refresh your framework packages, TypeScript, and RxJS.


This tutorial is for those who are interested in learning the new version of the Angular framework. The first version of the framework has been there for quite some time and it is only off-late that Angular 2 has become popular with the web development community.


The user should be familiar with the basics of web development and JavaScript. Since the Angular framework is built on the JavaScript framework, it becomes easier for the user to understand Angular if they know JavaScript.


There are numerous Angular books that cater to developers of various levels. Beginners should ideally look for those that provide clear and precise information about the fundamentals of Angular. Those who are already familiar with web application development should naturally choose books that cover more advanced concepts. Quick tip: check out the table of contents of a book to know if it will be helpful to you!


It is divided into two parts. The first covers techniques to use the Kanban method, extract design ideas, and keep an eye on value delivery with the help of mock-up tools. The second section touches on router-first architecture, design and development of business applications, and the scope of web development ideologies.


In the earlier days of web-based application development, JavaScript and jQuery brought significant advances to front-end web development. It provided simple and effective out-of-the-box capabilities such as client-side validation, modal windows, alert messages, animations, and even Ajax-based partial page updates. Enter the world of single page application frameworks and libraries. Single-page applications are web-based applications that load a single HTML page and dynamically updates the page as the user interacts with the application. SPAs use AJAX and HTML5 to create fluid and responsive web application front-ends, without constant page reloads. However, this means much of the work happens on the client side, in JavaScript. The origins of the term single-page application are unclear, though the concept was discussed at least as early as 2003 but often described as a self-contained website using JavaScript in a web application to display the user interface (UI), run application logic, and communicate with a web server.


The sample application for this article is a small shopping cart application and is a follow up to my previous article Test Driving MongoDB with .NET Core 2 which incorporated the latest version of Angular 2 with TypeScript for the front-end. For this article, I will walk through the development of the front-end application, but this time using the latest version of Vue.js while incorporating TypeScript into the mix. The back-end of the sample applicaton for this article will use a modified version of the .NET Core 2 backend project using a MongoDB database from my previous article mentioned above.


Like Angular, Vue.js comes with a full system for rapid Vue.js development. Version 3.0 of the Vue CLI installs the latest version of the Vue.js framework and provides complete project creation and scaffolding. The Vue CLI aims to be the standard tooling baseline for the entire Vue.js ecosystem including installing plugins, integration with webpack for hot-module replacement during development and production deployment features. 041b061a72
