Category: Data Binding and Directives

Angular directives are one of the framework’s most powerful features. They allow developers to manipulate the DOM, add reusable behaviors, and enhance templates without cluttering component logic. While Angular provides many built-in directives like *ngIf, *ngFor, and [ngStyle], creating custom directives allows you to extend HTML with your own functionality. This article provides a comprehensive…

Attribute directives are a key feature of Angular that allow developers to dynamically change the appearance or behavior of DOM elements. Unlike structural directives (e.g., *ngIf, *ngFor), which add or remove elements from the DOM, attribute directives modify the attributes or styles of existing elements. This post explores attribute directives in depth, including ngClass, ngStyle,…

Angular’s *ngFor directive is a powerful structural directive used to dynamically render elements for each item in a collection. It is fundamental for building dynamic lists, tables, menus, and other repetitive UI elements. This guide covers: 1. Introduction to *ngFor *ngFor is an Angular structural directive that adds or removes DOM elements based on an…

Angular provides powerful structural directives that allow developers to manipulate the DOM dynamically based on application state. One of the most commonly used directives is *ngIf. This directive enables conditional rendering, ensuring that elements are added to or removed from the DOM depending on a boolean expression. In this comprehensive guide, we will cover: What…

In Angular, structural directives are a special type of directive that alters the DOM structure by adding or removing elements dynamically. Unlike attribute directives that modify the appearance or behavior of an existing element, structural directives change the layout of the view by adding, removing, or manipulating elements based on conditions or data. This makes…

Angular is a modern front-end framework that enables developers to build dynamic and interactive web applications. One of the most powerful features of Angular is two-way binding, which allows for real-time synchronization between component properties and template elements. Two-way binding ensures that when a user updates an input in the template, the corresponding component property…

Event binding is one of the core features of Angular that allows applications to respond to user interactions. By binding events from the DOM to component methods, Angular makes it easy to handle actions like clicks, input changes, key presses, and form submissions. In this post, we will cover: how event binding works, syntax, practical…

Property binding is a core concept in Angular that allows developers to dynamically set properties of HTML elements, components, and directives based on data in the component class. It is fundamental for creating reactive, dynamic, and interactive applications. This guide will cover: 1. Introduction to Property Binding In Angular, the template and component class are…

Angular is a component-based framework that emphasizes reactive and dynamic user interfaces. One of the key features that makes this possible is data binding. Data binding in Angular allows developers to synchronize data between the component class (TypeScript) and the HTML template, ensuring that changes in the data automatically update the view and user interactions…
