Welcome to Dotnetskull Blog !!

Here at Dotnetskull blog, you’ll find beginner’s guide, tutorials, and articles to help you start learning coding. Dotnetskull blog is a free resource to find tutorials and guides on DOTNET technologies.

Each piece I write is ought to be the best on the web. I put so much time in curating content that I can’t let you guys consume the same generic advice and ideas. So I try to do things differently. 

I am Bala Krishna. Mainly, it’s me who’s writing everything here. I’m a full stack developer on DOTNET technologies. I usually write about a topic only when I believe I know enough to argue on it.

You’ll find talented authors who know their niche covering various topics on Dotnetskull blog. That’s how I keep Dotnetskull bloggers a gold standard for every topic we cover.

Dotnetskull blog is where I share everything I learn, practice, and preach. Not as an expert, but from the perspective of a reader.

My guest authors know their stuff because if they didn’t you won’t see them here. I’ve been very picky when it comes to approving blog posts for dotnetskull blog.

I started Dotnetskull blog in 2016 and it was a drift of enthusiasm that took me into the content marketing world. I started creating websites when I was 20. Writing about personal thoughts, then fitness and anything that came up on my mind.

Dotnetskull blog started as I tried to pen my knowledge from learning everyday experience from different blogs. Gathering enough knowledge to get better at marketing and conversion optimization.

Create Custom Form Control for ng-select in Angular

How to Create Custom Form Control in Angular  Why we create custom form control ? Normally, we used to create custom form control for re-usability.  The best advantage is that to add common functionality and features in this custom form control and extend the functionality as per our need and requirement.  And we can use everywhere into the application. But this example will tell you how to create custom form control to extend the functionality of  angular ng-select component.  We are adding a feature for this control, multi selection along with checkbox. Before that, we need to know what is the basic syntax of creating custom form control in angular. So, we start by implementing the ControlValueAccessor interface from @angular/forms into the component. This interface has three functions that need to be implemented and one optional functional. writeValue(obj: any): void { } registerOnChange(fn: any): void { } registerOnTouched(f

Use immutable data structures to avoid unnecessary change detection In Angular

In Angular, change detection is triggered whenever there is a change in the component's data or state. This can be a performance bottleneck if the component's data is updated frequently, and the component has a lot of child components or bindings. One way to optimize change detection is to use immutable data structures. Immutable data structures are data structures that cannot be modified once they are created. Instead, when a change is made to the data, a new instance of the data structure is created with the updated values. Here's an example of how to use immutable data structures in Angular: HTML import { Component } from '@angular/core'; import { List } from 'immutable'; @Component({ selector: 'app-list', template: ` {{ item }} ` }) export class ListComponent { items = List (['item 1', 'item 2', 'item 3']); addItem() { // The

Map Operator in RxJs

The map operator in RxJS is used to transform the emissions of an Observable stream. It applies a function to each emitted value and returns a new Observable with the transformed values. The original values are not modified. The map operator is often used in combination with other operators to create complex data flows. Advantages of the map operator in RxJS include: Transformation of data : The map operator allows you to transform the data emitted by an Observable, which can be very useful for manipulating the data in the way you need it. Efficiency : The map operator is an efficient way to modify data, as it does not modify the original data and creates a new Observable with the transformed data. Composability : The map operator is a composable operator, which means you can combine it with other operators to create more complex data flows. Clarity : Using the map ope

HTTP and grPC Communication protocols used in Microservices

Microservices architecture is an approach to building distributed systems that involves breaking down a large application into smaller, loosely coupled services that communicate with each other through APIs. There are several communication protocols used in microservices architecture, including HTTP and gRPC. HTTP: HTTP (Hypertext Transfer Protocol) is a widely used protocol for communication between web applications and servers. In microservices architecture, HTTP is used for communication between services as it's a well-established and reliable protocol that's widely supported. HTTP is simple and easy to use, and it supports a wide range of data formats like JSON, XML, and plain text, making it a popular choice for microservices communication. gRPC: gRPC is a modern, high-performance, open-source protocol for communication between microservices. It uses Google's Protocol Buffers as a data format, which is a language-neutral, platform-neu
