Naming Conventions

Image
Naming Conventions is very important for any application for better readability of  code. What is Naming Convention ?  Naming conventions are general rules applied when creating text scripts for software programming. They have many different purposes, such as adding clarity and uniformity to scripts, readability for third-party applications, and functionality in certain languages and applications. They range from capitalization and punctuation to adding symbols and identifiers to signify certain functions. Advantages of Naming Conventions are : 1. Consistency 2. Better understanding the code 3. Readability 4. Automation Types of Naming Conventions:  1. camelCase : First letter should be lower case. 2. PascalCase :   All words should be upper case. 3. kebab-case : Use dash symbol between word to word with lower case. 4. snake_case : Use underscore symbol between word to word with lower case. How and where these naming conventions will use ? Please check this pos...

Implementing DIP (Dependency Inversion Principle) in .NET Core project

Dependency Inversion Principle (DIP) is one of the SOLID principles that states that high-level modules should not depend on low-level modules, instead both should depend on abstractions. In .NET Core, we can implement DIP using various techniques such as Dependency Injection, Inversion of Control (IoC), and Service Locator. Here's a simple example of how to implement DIP using Dependency Injection in a .NET Core project: By following below steps, we can implement DIP in our .NET Core project using Dependency Injection. 1. Define interfaces for the low-level modules (dependencies) that the high-level module needs to use. For example: public interface ILogger {     void Log( string message); } public interface IDataProvider {     string GetData(); } 2. Create implementations for these interfaces.  For example: public class FileLogger : ILogger {     public void Log( string message)     {         // cod...

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...

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 ...

Aggregation and Association and Composition and Its differences with examples

 Aggregation, association, and composition are object-oriented programming concepts that define relationships between classes or objects. Here are their definitions and differences: 1. Aggregation: Aggregation is a relationship where one object has a reference to another object, but the referenced object can exist independently of the object that references it. The object that references the other is known as the container or owner, while the referenced object is known as the contained or member object. Here are a few examples of aggregation in C#: Example - 1 : A university has many departments, and each department has many students. In this case, the Department class is the container, and the Student class is the contained object. Here's an example code: public class Department {     public List<Student> Students { get ; set ; } } public class Student {     public string Name { get ; set ; } } Example - 2 : A car has an engine, and the engine can ...

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...

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 ...
