The Recipe for Angular 2 in a Java EE Environment: Frontend 2

  • This is the fourth article in our “The Recipe for Angular 2 in a Java EE Environment” series, with a more detailed description of the Frontend of the Angular2 and JavaEE Project.
  • It follows my third article about Angular 2 and Java EE that gave a detailed overview of the Frontend infrastructure of the Car Rental Project.
  • In this article about the Angular UI, we’ll go over the HTTP Service with its Types, the Detailview with its Validations, and 2 Tests, which are shown.
  • Line 23: sets the Value of the Input Parameter of the Component as the value of the Formcontrol.
  • Angular provides a flexible Validation infrastructure that can be used to write Form Validations that validate values dependent on each other.

We continue our look at creating frontend code in Angular using a Java EE environment. We’ll go over HTTP Services, Detailview and validations, and run 2 tests.

DHTMLX Gantt Chart Usage with Angular JS 2 Framework

  • To add data loading to our angular gantt chart, we are going to add task and link services.
  • Angular services can be injected using Dependency Injection mechanism and include data, function or some features necessary for your application.
  • We’re going to create a data service that we’ll use to provide our gantt chart with tasks.
  • So, our component can use that services to get tasks and links.
  • Also here we call our services to get function and then are waiting for response to put data to gantt.

AngularJS 2.0 From The Beginning

  • x, a key difference being that Angular 2’s Http returns observables.
  • We start by importing it together will all the types involved in doing http request:

    These are all the types and methods required to make and handle an HTTP request to a Web service: Http

    The Angular 2 http service that provides the API to make HTTP requests with methods corresponding to HTTP verbs like get, post, put, etc Response

    which represents a response from an HTTP service and follows the Observable

    which is the async pattern used in Angular 2.

  • Now in this article, we will demonstrate how to access or call GET method of a Web API controller to fetch the data.For this, we first need to add another project of type ASP.NET Web Application and select Web API option from the new dialog box.
  • Now, we can run the API project and access the GetEmployee method from the Browser to fetch the data but when we want to access the same Web API method from our Angular 2 project, then an error will occur called cross origin error.
  • Now, we can run the API project and access the GetEmployee method from the Browser to fetch the data but when we want to access the same Web API method from our Angular 2 project, then an error will occur called cross origin error.

In this article, we will discuss about the Http module in Angular 2.0.

AngularJS 2.0 From The Beginning

AngularJS 2.0 From The Beginning - Service (Day 11)  #dev #angular #web

  • An Angular 2 Service is simply a JavaScript function, including its related properties and methods which can perform a particular task or a group of tasks.
  • Angular 2.0 has greatly simplified the concept of Service over Angular 1.
  • Angular 2 simply changes the concept of Service.
  • @Injectable() lets Angular know that a class can be used with the dependency injector.
  • @Injectable() is not strictly required if the class has other Angular decorators on it or does not have any dependencies.

In this article, we will discuss services in Angular 2.0.

The Recipe for Angular 2 in a Java EE Environment: Frontend 1

  • This is the third article in our “The Recipe for Angular 2 in a Java EE Environment” series with a more detailed description of the Frontend of the Angular2 and JavaEE Project.
  • It follows my second article about Angular 2 and Java EE that gave a detailed overview of the Backend of the Car Rental Project.
  • In Lines 6-8, the Angular 2 Component is set up with the name of the template element, with the path to the template and the path to the CSS file.
  • Line 23 calls the CrRestservice with the ‘mnr’ Route Parameter and subscribes to its result.
  • This is the end of the first part of the description of the Angular UI of the Angular2AndJavaEE Project.

In web development, how the user reacts to your site is key. Read on to learn how to build the Frontend and UI aspects of your site with Angular2 and JavaEE.

AngularJS Application Architecture

AngularJS Application Architecture course by @simpulton #angularjs

  • One challenge when learning AngularJS is that most examples are trivial.
  • This series will demonstrate how to organize and tool your AngularJS application for real work.
  • All projects are different, but with the right set of modular tools you can build a foundation for success.
  • By introducing modules and sub-modules, domain models and state management with ui-router, we will start to establish best practices on how an AngularJS application should not only function, but fit together.
  • Be sure to check out Part 1: AngularJS App From Scratch: Getting Started

One challenge when learning AngularJS is that most examples are trivial. It is difficult to find materials on learning “real-world” patterns and practices.

The joy of Angular is that you are free to build an application in any form that you wish. MCV, MVVM, MVP, MV*whatever*… You get to decide! Freedom is wonderful.

“But what if I choose poorly?”

Good question.

This series will demonstrate how to organize and tool your AngularJS application for real work. It’s an opinion. A way that has worked on our own projects. Use it as a guide for building the solution that best suits the needs of your projects. All projects are different, but with the right set of modular tools you can build a foundation for success.

Building on the previous series, we are going to refactor Eggly to be modular and scalable. By introducing modules and sub-modules, domain models and state management with ui-router, we will start to establish best practices on how an AngularJS application should not only function, but fit together.

AngularJS 2.0 From The Beginning

#AngularJS 2.0 From The Beginning - #ngContent - Day 12 by @debasiskolsaha cc @CsharpCorner

  • In this article, we will discuss about the content template or ng-content in Angular 2.0.
  • This is now done in Angular 2.0 through modern web APIs, such as shadow DOM which is known as content projection.
  • Early alpha versions of Angular 2 adopted the element, however due to the nature of a bunch of Web Component helper elements being deprecated, it was changed to .
  • Angular provides three encapsulation strategies,

    To illustrate ng-content that, suppose we have a children component.

  • Then in the template, we can use directives, say, to specify the position of projected content to the ng-content with select=”area1″.

In this article, we will discuss about the content template concept in Angular 2.0.
