Create Custom Form Control for ng-select in Angular

Image
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 ...

Angular CLI Commands - Cheat Sheet

Image
Angular CLI (Command Line Interface) is one of the powerful tool that allows you to perform a lot of actions in an Angular project by using simple commands. We can use the CLI tool directly in a command shell, or indirectly through an interactive UI such as Angular Console.  The Best Advantage is that, can avoid manual process to create lot of stuff like create components, directives, feature modules, services... etc.  It automatically recompiles the source code files and refreshes the app in the browser.  Let's see, how to install CLI tool and what are those CLI commands. Installing the CLI is very quite easy. All we need to do, is to run the below command in Terminal or Console. It will install the CLI tool globally with respective version. Here we need to know two things before installing the CLI tool. We can install latest version or any version released by angular team based on your project need. Check the Versions list.✋ Angular CLI Setup  1. Globally - To ins...

Difference of High-Level Design (HLD) and Low-Level Design (LLD)

High-Level Design (HLD) and Low-Level Design (LLD) are software design concepts that are not specific to any programming language. However, to illustrate the differences between HLD and LLD, we can use C# programming language examples. Suppose we are designing a software system that involves creating a payment gateway application in C#.  Here are examples of HLD and LLD for this system: High-Level Design (HLD): Define the functional requirements of the payment gateway system, such as processing payment transactions, handling errors, and providing a user interface. Identify the non-functional requirements, such as performance, scalability, and security. Identify the key components of the payment gateway system, such as payment processing engine, database, user interface, and error handling. Create an architecture diagram that shows how these components will fit together to form the payment gateway system. In HLD, the focus is on defining the system's overall structure and architectu...

Configure the API gateway in Microservices Architecture with example in .NET Core

API Gateway in Microservices Architecture In a microservices architecture, an API Gateway is a layer that sits between clients and the microservices that provide the necessary functionalities. It acts as a single entry point for all client requests and handles communication between the clients and the underlying microservices. The API Gateway serves as a mediator between the client and the backend services. It receives incoming requests from clients and routes them to the appropriate microservice. It also handles authentication, authorization, load balancing, and other cross-cutting concerns such as rate limiting, caching, and request/response transformation. By providing a single entry point and a unified interface for clients, the API Gateway simplifies client access to the system and helps to decouple the client code from the underlying microservices. It also provides a central point for monitoring and logging of all the incoming requests, making it easier to identify and troublesho...

Domain Driven Design (DDD) in .NET Core

Domain-Driven Design (DDD) is an approach to software development that emphasizes the importance of the business domain in the software design process. It is a set of principles and practices aimed at building software systems that are aligned with the business needs and requirements. The main idea behind DDD is to create a shared understanding of the domain model between the domain experts (business stakeholders) and the software developers. This is achieved by using a common language and a set of tools that allow for the domain model to be explicitly represented and manipulated in code. In DDD, the domain model is the central focus of the software design process. It is a representation of the core business concepts and rules that govern the behavior of the system. The domain model is expressed in code using object-oriented programming techniques, and it serves as the backbone of the software system. DDD also introduces several design patterns and ...

Recommended Visual Studio Code Extensions for Angular Development

Every Angular Developer should know these recommended VS Code Extensions. I guess most of the developers using the Visual Studio Code tool for coding. There are large number of extensions are available in market place. But I choose necessary extensions, which is related to angular development. It will speed up your work when you're doing development. Extensions can help to improve productivity and code quality for Angular development in VS Code. By automating tasks and enforcing best practices, these extensions can help developers to create better code more quickly and with fewer errors. Angular Language Service - Provides rich editing experience for Angular templates with autocompletion, diagnostics, and jump-to-definition features. Angular Snippets - Provides a collection of Angular snippets to quickly insert common code structures, such as components, directives, and services. Angular Console - Provides a GUI tool for generating and managing Angular projects and associated fi...

Tightly Coupled and Loosely Coupled in .NET Core with example

In .NET Core, tight coupling and loose coupling refer to the way software components are designed and connected to each other. Tight coupling in .NET Core means that two or more software components are highly dependent on each other, making it difficult to modify or replace one component without affecting the others. This can lead to maintenance and testing challenges, as well as reduced flexibility and scalability. Loose coupling in .NET Core, on the other hand, means that software components are designed to be independent and have minimal interdependence. This is achieved by using interfaces, dependency injection, and other techniques to reduce the direct dependencies between components. Loose coupling allows components to be more easily replaced, modified, or extended without affecting the rest of the system. Summary, loose coupling is generally preferred in .NET Core because it makes software more flexible, maintainable, and scalable. Advant...
