High Performance Angular Grid With Web Sockets

You may have come across the requirement to push data in real-time to an Angular Grid. To push data to the browser, you need a technology called WebSocket. You can implement that using Node.js or ASP.NET SignalR. For the purpose of this article, we will use Web Sockets with Node.js.
In the first half of this article, we will create an API which will use Web Sockets to push data to the client, and, in the second half of the article, we will create an Angular application to consume that. In the Angular application, we will use Ignite UI for Angular Grid. However, you can also use a simple HTML table to consume data in real-time from the web socket. In this article, we will learn to consume data in real-time from a Node.js Web Socket in a HTML table as well as Ignite UI Angular Data Grid. We will also look at the difference in performance in these two approaches.

How to Create Your First Angular Element

Angular Elements allow us to create reusable Angular components, which can be used outside of the Angular application. You can use an Angular Element in any other application, built with HTML, React, etc. Essentially, Angular Elements are normal components, which are packaged as Custom Elements. You can learn more about Custom Elements here.
Angular Elements are reusable components, which can be used outside Angular.

How to Add Ignite UI to an Existing Angular Project

Let’s say that you’re already working on an existing Angular project, and you wish to add the Ignite UI for Angular library into the project. In this blog post, we will follow a step-by-step approach to add Ignite UI Angular library into an existing Angular project.
Step 1: Add Ignite UI for Angular library
Begin by adding the Ignite UI Angular library in the project. We can use npm to do this. So, run the command shown below to install Ignite UI for Angular.

Angular 6, Part 3: Lifecycle of a Component

In this article, we will discuss the lifecycle of components. Since, in Angular, a component is the main building block the application, it is very important for us to understand the lifecycle processing steps of the components so that we can implement that in our applications.
Lifecycle Method
In Angular, every component has a life-cycle, a number of different stages it goes through. There are 8 different stages in the component lifecycle. Every stage is called as lifecycle hook event. So, we can use these hook events in different phases of our application to obtain control of the components. Since a component is a TypeScript class, every component must have a constructor method. The constructor of the component class executes, first, before the execution of any other lifecycle hook events. If we need to inject any dependencies into the component, then the constructor is the best place to inject those dependencies. After executing the constructor, Angular executes its lifecycle hook methods in a specific order.

Angular and Swagger: Experiences Learned

Recently I was fortunate enough to be a part of a project where we were building an application from scratch into an Angular front-end application with microservices in the backend. Swagger was used as the contract between the UI and microservices.
In this post, I talk about the things I learned from this project experience, like how to use Swagger to define the endpoints of the microservices, integrating Swagger-Generated code into Angular, and working with the configuration including oAuth2 tokens, among other “gotchas."

Reactive Forms in Angular

As we saw in the last article, there are two types of form development approaches that we can use in Angular. The first one is template-driven development and the other is the reactive forms approach. Let’s explore what reactive forms are and how to validate reactive forms in Angular.
What Are Reactive Forms?
This approach uses the reactive form of developing the forms that favor the explicit management of data between the UI and the model. With this approach, we create a tree of Angular form controls and bind them in the native form controls. As we can create the forms control directly in the component, it makes it a bit easier to push the data between the data models and the UI elements.

What Is Better for Web Development, React or Angular?

It is considered in IT world that customers can completely rely on their technology partners to get their products successfully delivered but probably they have never tried to conduct their own research on the stacks, technologies, or tools required for their projects. In this article, you will learn what is the difference between React and Angular and how to make your own choice.
Angular Pros and Cons
542 Angular jobs are currently offered on Indeed in the United States. Surely, the prime advantage of Angular is its popularity. It could be argued that it is Google that affected the way7 Angular is treated. However, the first version of Angular has quickly become popular because those developers who came from other development environments found there a familiar MVC pattern for building single-page applications (SPAs). After upgrading AngularJS and modifying some of its features, the popularity of the framework skyrocketed. And there is no wonder that today the IT market has a serious demand for Angular developers. Moreover, it is one of the few frameworks which provides a set of rich possibilities and components for creating user interfaces.

Template-Driven Forms in Angular

Forms are the main building block of any application. We use forms for logins, registration, submitting help requests. So, whatever form we are developing must be user-friendly. For example, when something goes wrong, it should have an indication as to why, etc.
Coming to Angular Forms, Angular provides two approaches for developing forms which are Template Driven and Reactive. Let’s try to explore the template-driven approach in this article
