Javascript 
function parseStringToDecimal(inputValue: string): Number {
  let value: number;

  if (inputValue === '0.00' || Number(inputValue) === 0.00) {
    value = 0.00;
  } else if (inputValue === '') {
    value = null;
  } else {
    value = parseFloat(inputValue.toString().replace(/,/, ''));
  }

  return value;

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...

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 ...

How to Delete Empty Rows or Null Rows in Datatable Example:  In this application we can see how to Delete Empty Rows or Null Rows in Datatable. Mostly this issue comes from while uploading the excel(.xls,.xlsx) file data into your sql table through datatable in windows application or web application. In rare cases,we can see while getting data from excel to datatable it will copies the empty rows also. Below Code. C# public DataTable DeleteEmptyRowsFromDataTable(DataTable dt) { for (int i = dt.Rows.Count - 1; i >= 0; i--) { if (dt.Rows[i][1] == DBNull.Value) dt.Rows[i].Delete(); } dt.AcceptChanges(); return dt; }

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...

CORS (Cross-Origin Resource Sharing) in .NET

-
CORS stands for Cross-Origin Resource Sharing. It is a security feature that allows web pages from one domain to access resources (such as APIs) on another domain. When a web page attempts to access a resource on a different domain, the browser will send a CORS request to the server hosting the resource. The server can then choose to allow or deny the request based on the domain of the requesting web page. CORS is important because it helps to prevent malicious attacks, such as cross-site request forgery (CSRF) and cross-site scripting (XSS). By enforcing same-origin policies, CORS helps to protect users from unauthorized access to their sensitive data. We use CORS to enable cross-domain communication between web pages and APIs. Without CORS, web pages would only be able to communicate with APIs hosted on the same domain. With CORS, we can make APIs available to web pages on other domains, allowing for a more flexible and dynamic web. CORS is co...

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 ...

Clean Architecture in a C#

-
Clean Architecture is a software design pattern that separates the application into independent layers, where each layer has a specific responsibility and interacts with other layers through well-defined interfaces. The main goal of clean architecture is to create a flexible, testable, and maintainable software system. By following this architecture, we have created a flexible, testable, and maintainable software system. The domain layer is independent of any external dependencies and frameworks, making it easy to test and change without affecting other layers. The application layer contains the use cases or application-specific logic, which is decoupled from the infrastructure Here's an example of how to implement Clean Architecture in a C# project: 1. Domain Layer: This layer contains the business logic and domain-specific entities. It should be independent of any external dependencies and frameworks. C# ...

RxJs Operators in Angular

-
RxJS (Reactive Extensions for JavaScript) is a library for reactive programming using Observables, which are a way to represent asynchronous data streams. RxJS provides a set of operators that can be used to transform, filter, combine, and manipulate these data streams. In RxJS, operators are functions that take one or more observables as input, and return a new observable. These operators can be chained together to create complex data stream transformations. RxJS operators have several advantages and disadvantages that are worth considering: Advantages: Composable : RxJS operators are composable, which means they can be combined in a variety of ways to create complex data stream transformations. This allows for a high degree of flexibility and modularity in reactive programming applications. Asynchronous : RxJS operators are designed to handle asynchronous data streams, which are common in modern web applications. This makes them well-suited for tasks like handling user input, making ...
