What are Signals in Angular? A Signal is a wrapper around a value that notifies interested consumers when that value changes. A signal can contain any value, from primitives to complex data structures. In Angular, Signals are a system (or reactive primitives) that granularly (closely) tracks and updates how and where your state is used throughout the application, allowing the framework […]
What is Reactive Programming? In computing, Reactive programming is a way of writing code, where you deal with “data streams” and “changes automatically”. It is telling the computer what you want to do, rather than how to do it step by step. This approach helps you to keep your program structured and easier to understand for others. […]
What is PrimeNG? PrimeNG is a cohesiveUI component library specifically designed for Angular applications. It provides a collection of ready-to-use UI components (e.g., themes, icons, and components) such as “input fields,” “buttons,” “tables,” “lists,” “cards,” etc, for building user interfaces. It allows developers to integrate these into their applications rather than building them from scratch. However, PrimeNG is not […]
What is Angular Material? Angular Material is a UI component library developed by the Angular team to integrate easily with your Angular applications. This library is “specific” to the Angular framework and provides a set of reusable, accessible, well-tested components that help create a responsive modern user interface (UI). It also provides tools that help developers to create custom UI components with […]
Overview of Angular Libraries Many applications face similar challenges, like providing a consistent user interface, displaying data, and enabling data input. To resolve this issue, developers create universal solutions for specific domains that can be customized and reused across different applications. Such a solution can be built as Angular libraries and these libraries can be published and […]
What is RxJS? The RxJS is a library that stands for Reactive Extensions JavaScript. It allows you to work with the synchronized data stream. It is used for “reactive programming”, which is a way to develop an application that reacts to changes instead of explicitly writing code to handle them. What is Observer Pattern in Angular? In Angular, […]
What is Singleton Pattern in Angular? In Angular, the singleton pattern is a design pattern having a single instance of a class throughout the entire application and provide the global point of access to it. This design pattern is useful when you want to share a single resource to the entire application such as without recreating it; […]
Lazy Loading in Angular In Angular, Lazy Loading is a design pattern developed by the google angular team to “enhance the application performance”. The lazy-loading technique loads only the required components and module at a time rather than loading all together. For example, suppose you have an Angular application with multiple feature modules, like a dashboard, user profile, settings, and reports. Instead of loading all these modules […]
Design Patterns In software engineering, design patterns are like a reusable blueprint or a template for solving common problems in software design. A few of them might also known as a “software design pattern”. Design patterns help developers to apply best practices in software development, which enhance the performance, maintainability, and scalability of software applications. By using the […]
Angular NgModule In Angular, the NgModule is a class marked (or defined) with the @NgModule decorator, which specifies it as an Angular module. This decorator provides metadata that tells Angular how to compile and run the module code and configure the DI (dependency injection). Here is the snippet of the @NgModule in Angular: import{ NgModule }from’@angular/core’;import{ BrowserModule }from’@angular/platform-browser’;import{ AppComponent }from’./app.component’;import{ MyFeatureModule }from’./my-feature/my-feature.module’;import{ MyService }from’./my-service.service’;@NgModule({ declarations:[ […]
