Monolith vs Microservices in .NET Core

  Monolith vs Microservices in .NET Core 1. Monolithic Architecture Definition : A single, unified codebase where all modules (UI, business logic, data access) are part of one large application. Deployment : Deployed as a single unit (e.g., one .exe or .dll ). Scaling : Scales by cloning the entire application (vertical/horizontal scaling). Communication : Internal method calls (no network). Tech Stack : Typically limited to a single framework/runtime. Example in .NET Core : An ASP.NET Core MVC app with controllers, services, and EF Core all in the same project. Single database, one codebase, deployed to IIS/Kestrel. 2. Microservices Architecture Definition : A collection of small, independent services, each responsible for a specific business function. Deployment : Each service runs independently (often in Docker containers). Scaling : Scale individual services based on demand. Communication : Via APIs (REST, gRPC, message queues). ...

Angular, Angular Router, Routing State, Angular Navigation, Angular Example, SPA, Angular Routing Tutorial

Routing State in Angular with Example | Angular Tutorial Routing State in Angular with Example Routing in Angular allows navigation between views. When you need to pass data during navigation, Angular’s routing state comes in handy. Here's a practical guide with example code and best practices. What is Routing State? Angular's Router allows passing state using the state property in NavigationExtras . This is useful for transferring temporary data. Step-by-Step Example 1. Define Routes const routes: Routes = [ { path: 'home', component: HomeComponent }, { path: 'details', component: DetailsComponent } ]; 2. Navigate with State this.router.navigate(['/details'], { state: { productId: 123, productName: 'Angular Guide' } }); 3. Receive State const navigation = this.router.getCurrentNavigation(); const state = navigat...

Preparing for an AngularJS interview

  Certainly, when preparing for an AngularJS interview, it's important to have a solid understanding of the framework, its features, and common development practices. Here are some additional points you might find helpful: 1. AngularJS vs. Angular (Angular 2+): Be prepared to explain the difference between AngularJS and the newer versions of Angular (Angular 2 and above). Mention that AngularJS is sometimes referred to as "Angular 1" and highlight the major architectural changes and improvements introduced in Angular 2+. 2. Directives: Understand that AngularJS heavily relies on directives to extend HTML with new attributes and elements. Familiarize yourself with built-in directives like ng-model , ng-repeat , and ng-if , and explain how to create custom directives. 3. Controllers: Discuss the role of controllers in AngularJS. Controllers are responsible for defining the behavior of a part of the web page. Explain how they are used to manipulate data and interact with ...

Certainly, here are 10 interview questions and their answers for AngularJS

  1. What is AngularJS, and what are its key features? Answer: AngularJS is an open-source JavaScript framework developed by Google. It is used for building dynamic web applications. Key features include two-way data binding, dependency injection, directives, and a modular architecture that promotes reusable components. 2. Explain two-way data binding in AngularJS. Answer: Two-way data binding in AngularJS means that changes to the model automatically reflect in the view, and vice versa. It ensures that the view and model are always in sync, making it easier to develop responsive user interfaces. This is achieved using directives like ng-model . 3. What is dependency injection in AngularJS, and why is it important? Answer: Dependency injection is a design pattern in AngularJS that allows components to request their dependencies rather than creating them. It promotes modularity, testability, and the reusability of components. AngularJS's built-in dependency injection system handl...

Angular vs. React: A Comprehensive Comparison

  Introduction In the world of modern web development, Angular and React are two of the most popular JavaScript frameworks for building web applications. While both serve similar purposes, they have distinct differences that cater to varying development needs. In this article, we will delve into the differences between Angular and React, helping you make an informed decision about which one is best suited for your project. Origins and Development: Angular : Developed and maintained by Google, Angular (or Angular 2+) is a complete and opinionated framework. It is a rewrite of the original AngularJS, with a focus on component-based architecture and a strong emphasis on TypeScript. React : Developed and maintained by Facebook, React is a JavaScript library for building user interfaces. React is unopinionated and focuses on the view layer of the application, allowing developers to choose other technologies for routing, state management, etc. Architecture: Angular : Angular follows the ...
